171-544: Santiago Papasquiaro is a city located in a valley situated on the eastern slopes of the Sierra Madre Occidental in the Mexican state of Durango . As of 2010, the city of Santiago Papasquiaro had a population of 26,121, while the municipality has a census population of 48,482 as of 2015. It is the fourth largest community in the state in terms of population, and is the municipal seat of the municipality of

342-633: A marine basin which separated the island arc that came to form the Guerrero terrane from the accretions that came to form the Sierra Madre terrane. It contains a lower formation made up of pillow basalts with pillow breccias , tuffs, and shales underlying a group of pelagic limestones , oozes , and turbidites . Covering the southern basement are sedimentary and metamorphosed sedimentary rocks containing argillite , limestone, volcanic schist , slate , and greywacke which were exposed in

513-416: A source of water , in an otherwise arid environment from the increased precipitation from the mountain range. As such, rivers that have headwaters in the mountains provide water for irrigation in the surrounding lands. The need for water to irrigate prompted the construction of dams, which has been the source of several environmental concerns in the area. The northern end of the range is more arid; hence,

684-670: A city is Salvatierra . Guanajuato is between the arid north of the country and the lusher south, and is geographically part of the Trans-Mexican Volcanic Belt , the Mexican Plateau . It was initially settled by the Spanish in the 1520s due to mineral deposits found around the city of Guanajuato, but areas such as the Bajío region also became important for agriculture and livestock. Mining and agriculture were

855-448: A desert landscape. Oak forests are the predominant plant life, and extend into the lowland deserts. This forest and canyon land provided a place for a variety of indigenous people to live, until Spanish settlers with associated mestizos came into the area to found towns for the silver mines in the area. The major industries in the area now are agriculture and forestry, which have become contentious because of land degradation and

1026-505: A few towns of note, including Creel, Chihuahua , with 5,000 inhabitants; it serves as a stop on the train line. South of Copper Canyon is the town of El Salto, Durango , situated along highway 40. To the west is Copala, Sinaloa . To the south live the indigenous Cora people in the towns of Jesús María and La Mesa del Nayar. In addition, 1,000 people live in the village of Huajimic in Nayarit. The Bolaños River valley of Jalisco

1197-780: A group consisting of Miguel Hidalgo y Costilla , Ignacio Allende , Juan Aldama , Miguel Domínguez and more, began to plan an armed revolt against the colonial government. In 1810, the plot was discovered and Hidalgo decided to put their plans into action in September instead of the planned date in December. On 15 September, Miguel Hidalgo y Costilla declared the Grito de Dolores in the town of Dolores (Hidalgo). Hidalgo, accompanied by Ignacio Allende, left Dolores with about 800 men, half of whom were on horseback. Through sheer numbers, Hidalgo's army had some early victories, progressing through

1368-520: A large impact on the area economically, accounting for most home buyers. Estimates of foreign residents range from 8,000 to 12,000 with about 7,000 of these from the United States alone. This makes San Miguel one of the largest American communities in Mexico, large enough to warrant its own U.S. consulate to provide services such as notary and passport. Since that time, Guanajuato has had

1539-521: A mixed Catholic-indigenous belief system. While outwardly Catholic, many rituals still follow the cycles found in nature, such as planting and harvesting and lunar cycles. The most important "spirit guides" are the eagle and water, with the Virgin of Guadalupe playing an important role as Universal Mother. One important saint is Isidore the Laborer , who is connected to the bringing of rain. The Otomis of

1710-630: A number of cases not paid at all. Agricultural production reached a peak at the end of the 19th century, earning the state the nickname of the "granary of the Republic". Industrialization took hold in cities such as León , Salvatierra , Celaya and San Francisco del Rincón , making shoes, textiles and hats. One battle of the Mexican Revolution occurred in Celaya in 1915 between the troops of Álvaro Obregón and Francisco Villa . Many from

1881-588: A rate of increase of 2.04%. Manufacturing accounts for 28% of total GDP, down slightly from a high of over 30%. Its importance is followed by commerce at 16.3% and real estate at 11.2%. Agriculture, which includes forestry, fishing and hunting accounts for 4.6. Other activities include financial and other professional services (17.6%) and transportation and storage at 11.8%. Employment figures break down differently with 13.2% employed in agriculture, 36.4% in mining and industry and 47.3 percent in commerce, services and tourism. There are two significant migration patterns in

2052-624: A series of Paleozoic sedimentary sequences from a deep marine environment underlying it, considered by some to be part of the Cotes Terrane and by others to be transported . In some areas, distinct sedimentary rocks can be identified by shallow-water Silurian and Mississippian sedimentary rocks underlying deep-water Pennsylvanian and Permian , which are divided by Mississippian rhyolite . The Permian clastics contain some detrital rock that sit alongside low-grade metamorphosed sedimentary and volcanic rocks with serpentinite. South of

2223-629: A series of folds, thrust , and left lateral faults date from the middle Miocene. This may be evidence for a left transpressional shear zone . The area between this boundary and the Aguascalientes fault is filled with numerous grabens and half-grabens, as well an east–west left shear zone, the El Roble shear zone. At the west end of these grabens and half-grabens are the Pochotitan and the more northerly San Pedro fault systems, which form

2394-493: A set of seven inactive volcanic craters in the northwest and southwest of the Santiago Valley. The volcano cones rise abruptly out of the ground with craters up to one kilometer across. Locals call the formations "holes" ( hoyos ) and they are named La Alberca, La Cíntora, Estrada, Blanca, Alvarez, Solís and Rincón de Parangueo. La Cíntora and Rincón de Parangueo contain cave paintings and evidence that people once lived in

2565-466: A significant rise in violent crime, the second highest homicide rate in the nation, with Mexican President López Obrador calling out the state's attorney general for inaction on the matter. There is a growing presence of East Asians, primarily Japanese, in the Bajio region. As of early 2014, there were more than three thousand Japanese immigrants in the Bajio area, and it's claimed that this population

2736-573: A smaller scale, mineral deposits are distributed in formations of the Sierra Madre, although the events that placed these deposits vary throughout the mountains. The Guerrero composite terrane contains many of the economic deposits, often found in ore bodies younger than the Cretaceous. Gold and silver deposits most commonly occur in the altered andesites of the early volcanics, typically these deposits are between 30 and 50 million years old. These are believed to be caused by later intrusions into

2907-539: A specialty of Salamanca, producing mostly decorative items. Most of the items made in Guanajuato city are still done Baroque style and sold in the city center. Pénjamo is one of very few places outside of the state of Jalisco to produce tequila . It is the home of the Tequila Corralejo brand, which is still made on the now former hacienda of Corralejo. The installation gives tours and has a museum called

3078-435: A summer monsoon , and two dry seasons each year. Air pressure changes in northwestern Mexico and the southwest United States are the main causes of seasonal variation in the Sierra Madre. A high pressure area that rests over the mountains in the winter begins to move north of the mountains into New Mexico during the month of June. The high pressure begins to break down and move south during September or October; however,

3249-407: A thick core covered by volcanics and eroded by numerous rivers. Some have suggested that the basement of the mountains have numerous intrusions made by mafic magma . At their surface, the mountains are made up of large-scale ignimbrite sheet that has been incised by rivers flowing from rainfall in the mountains. The surface of the plateau is almost exclusively from the second series of flows causing

3420-529: A tradition of making hats since the 18th century. Traditionally, the hats were made from palm fronds brought from the Michoacán coast area, but today many workshops and factories use synthetic fibers. In traditional workshops, the work is divided by sex, with women weaving the fibers together and men pressing it into shape, putting in the supports and other details. The quality of the hats made here has made them exportable. In San Luis de la Paz and Coroneo, wool

3591-456: A variety of crafts. The economy in this area continues to grow although there has been some drop in its percentage of GDP due to drop in prices for a number of manufactured products. The state has two large thermoelectrical plants in Salamanca and Celaya. Oil refining in Salamanca received raw material through pipelines from Poza Rica, Veracruz and from Tabasco . One traditional industry

3762-630: A wide number and variety of micro-climates, although average temperatures vary only between 16 and 19 °C. It lowest point is a canyon called Paso de Hormigas in Xichú at 650 meters above sea level with a very warm climate suitable for tropical fruit. The highest point is Pinal de Zamorano at 3,300 meters, followed by El Picacho de Pueblo Nuevo, El Zorillo and El Cuervo, all above 2,700 meters. The largest changes are seen in arid versus wetter zones, which can often be relatively nearby, with foliage changing from rainforest to pine forest to desert landscapes. In 1997,

3933-399: A wood called "patol" and juniper , but today they work with various woods such as walnut, cedar , mahogany and Ceiba pentandra (the kapok). Celaya is known in much of Mexico for its cajeta , a kind of spreadable caramel, often made with goat's milk, sugar and cinnamon. The mixture can be eaten straight from a spoon or used in a variety of recipes. The best known outlet for cajeta in

4104-572: Is Oto-Pamean and related to their neighbors, the Otomi. Most Chichimecas are found in the municipality of San Luis de la Paz, in the community of Rancho Uza or Mision Chichimeca. This community subdivides into the Mision de Abajo in the east and Mision de Arriba in the west. This area borders lands of the Huasteca and Pame groups, and there have been conflicts among the three. The Chichimeca Jonaz have

4275-409: Is a high plateau of volcanic rock that is eroded in areas to reveal a basement composed of plutonic and sedimentary rocks underlying the two groups of extrusive volcanics. The lower of these groups is a series of volcanic rocks formed by lava flows . The surface of the plateau is made up of a second series of volcanic ignimbrites , covered mostly by clay rich organic soils . Some intrusions in

4446-810: Is a major mountain range system of the North American Cordillera , that runs northwest–southeast through northwestern and western Mexico, and along the Gulf of California . The Sierra Madre is part of the American Cordillera , a chain of mountain ranges (cordillera) that consist of an almost continuous sequence that form the western "sounds" of North America , Central America , South America , and West Antarctica . The Spanish name sierra madre means "mother mountain range" in English, and occidental means "western", these thus being

4617-610: Is a series of low, gentle mountains in the center of the state that are part of the Sierra Madre Occidental. They cover 12 municipalities: Ocampo , San Felipe , León, Silao, Guanajuato, Dolores Hidalgo, San Miguel de Allende, Irapuato, Salamanca, Santa Cruz de Juventino Rosas , Comonfort and Apaseo el Grande . Wild vegetation runs from tropical rainforest to arid grasslands with cactus, with cypress trees along rivers and other surface water. Wildlife includes raccoons, quail, rabbits, skunks and migratory birds. The land

4788-423: Is also a belt of iron deposits further east. Most soil in the mountains is covered by an organic -rich layer over layers rich in clay . Soils are commonly phaeozems that are up to 100 centimetres (39 in). Some soils are cambisols that are less than 2 metres (6.6 ft) deep and well- drained . Due to the high clay content, which blocks water from being absorbed into the soil, larger rock particles in

4959-455: Is characterized by the fact that evaporation often exceeds precipitation. Most of the vegetation in these areas is arid grassland with desert plants such as nopal. These climates cover about 40% of the state, mostly in the north. Semiarid temperate regions are found in the municipalities of San Felipe, San Diego de la Unión , San Luis de la Paz, part of Dolores Hidalgo and San José de Iturbide , where precipitation varies between 400 and 500 mm and

5130-499: Is extracted from the Dolores Hidalgo region and most is produced in Dolores Hidalgo, San Miguel de Allende and the city of Guanajuato. Another area noted for its work is Tarandacuaro, which makes high-fire ceramics. The two best-known workshops are Fabrica Javier Servin and Taller Checuan. The ceramics of this area have distinctive, very intricate, mostly geometric designs, which are painted on by hand. The municipality promotes

5301-553: Is formed by the range is cut by deep river valleys. This plateau is formed from volcanic rock overlying a basement of metamorphic rock. This uplift has caused changes in weather patterns; increased rainfall occurring in the mountains has provided areas where ecosystems can form in wetter areas than surrounding land. This water source forms watersheds that provide the arid surroundings with water that makes it possible to irrigate and farm crops. The wet ecosystems are islands of biodiversity, differing significantly from what would otherwise be

5472-503: Is found mostly in the most rugged and inaccessible areas and includes deer, coyotes, eagles and rattlesnakes. La Sierra Gorda is shared between Guanajuato and Querétaro and is considered an important biosphere. This area is the most rugged in the state where most of the natural areas and small villages remain intact due to their inaccessibility. The Sierra Gorda is part of the Sierra Madre Occidental, with extreme variations in its geography and climate. The rugged terrain means that there are

5643-517: Is larger than the historical Japanese community in Mexico City . The Guanajuato government believes that by 2016 there will be five thousand families installed in the region. This immigration is being driven by foreign investment in the Bajio, especially in the automotive sector. The large Japanese community prompted the opening of a Japanese consulate in Leon. There is also a Korean community in

5814-449: Is located in central Mexico and is bordered by the states of Jalisco to the west, Zacatecas to the northwest, San Luis Potosí to the north, Querétaro to the east, and Michoacán to the south. It covers an area of 30,608 km (11,818 sq mi). The state is home to several historically important cities, especially those along the "Bicentennial Route", which retraces the path of Miguel Hidalgo y Costilla 's insurgent army at

5985-461: Is marked by different volcanic processes. The first was a continuation of the Oligocene flare-up, which lasted through the early Miocene. This may be a distinct second occurrence of the same process, placing silica-rich lava above Oligocene rocks. Also in the early Miocene more intermediate basaltic andesites occur along faults and in grabens. Beginning in the early Miocene and continuing into

6156-639: Is not a major economic activity as it is limited to the small rivers and lakes of the region. Of the two major lakes, one is shared with neighboring Michoacán state. Of the fish is that is caught or raised, most is carp , followed by mojarra . There are 150,000 hectares of forest in the state, which about half theoretically exploitable. However, forests in this state have been historically depleted with species such as holm oak, pine and oyamel in danger of extinction. The lack of forest cover has led to erosion and other environmental problems. Most forestry products come from pine and holm oak, with most being harvested in

6327-465: Is not considered a particularly active segment of the state's population with no data as to the percentage of the state's GDP it represents. Most crafts over time have become specialties of more or more municipalities. Majolica pottery has been made in the state since colonial times after being introduced by the Spanish. Since then, areas have developed specialties in form and decoration, but techniques have not changed much for over 400 years. Most clay

6498-483: Is now the site called Chupícuaro , and their influence was widespread being found in the modern states of Zacatecas, Querétaro, Colima , Nayarit , Hidalgo, State of Mexico, Michoacán and Guerrero . Chupícuaro cities were associated with the Toltec city of Tula and when this city fell, these agricultural cities of Guanajuato also went into decline. This and a prolonged drought cause these cities to be abandoned between

6669-651: Is populated with mining communities, such as San Martín de Bolaños , which has a population of around 3,000. Few paved roads cross the mountains, meaning that travel times can be long, even between cities that are relatively close. In the north, Mexico Federal Highway 16 connects Hermosillo , Sonora and La Junta, Chihuahua. In the mountains, the La Entrada al Pacifico Corridor is an incomplete road intended to connect Los Mochis , Sinaloa and Chihuahua. Durango and Mazatlán are connected by highway 40 , around 24 degrees north latitude. The Sierra Madre Occidental

6840-592: Is productive, especially for fruit orchards producing guavas , tejocote , apples, limes, quince and more. Desert fruits such as cactus pears (tuna), garambullos and xoconostle are also produced commercially. The state's best-known geographical region is the Bajío, a relatively low and flat area of between 1,700 and 1,800 meters that surrounds the Lerma River and its tributaries. Centered in Guanajuato, parts also extend into Querétaro and Jalisco. This low area

7011-413: Is simply sold next to the parish church. Flavors include sapote , mango, honey, aloe , tequila and banana. Mining, manufacturing and construction accounts for over 27% of the state's GDP. Mining is a traditional economic activity for the state, with deposits making it one of the world's richest areas in the past. However, in comparison gold and silver ores are mostly depleted today. Gold and silver ore

Santiago Papasquiaro - Misplaced Pages Continue

7182-478: Is still mined with silver still the major ore produced, followed by gold, lead, copper, zinc and sulfur . Most employed in mining are still related to metals rather than non-metals. Other products being mined or being studied are mercury , tin , copper , lead , sand, fluorite , feldspar , lime, kaolin , and more. While the agricultural sector, which includes crops, livestock, fishing and forestry activities, accounts for only 4.6% of Guanajuato's current GDP,

7353-532: Is the Sierra Gorda Biosphere Reserve . In Guanajuato, it extends over 236,882 hectares and contains 182 bird species, 42 mammal species and 84 plant species, including two recently discovered ones, Beaucamea compacta and Calibanus glassianus . The park contains a number of species in danger of extinction, including the black bear and the puma . The climate is semiarid with variations in temperature due to altitude changes, but most of

7524-735: Is the 20th-largest of Mexico's states, with an area of 30,589 km . It has an average altitude of 2,015 meters (6,611 ft) above sea level, with its territory divided among three of Mexico's physical regions, the Sierra Madre Oriental, the Mexican Plateau and the Trans-Mexican Volcanic Belt. The Sierra Madre Oriental in Guanajuato consists of the Sierra Gorda and the Sierra del Azafrán in

7695-562: Is the making of shoes and other leather items, especially in León. This industry grew 50% from 2009 to 2010 in the number of enterprises dedicated to it. They now total 7,981 and employ 297,413 people directly and indirectly according to INEGI . In 2010, Volkswagen announced a new motor plant to be built in Silao . The project is projected to cost US$ 550 million and will employ 700 people making 330,000 motors per year starting in 2013. A spokesman for

7866-513: Is the source of its name, coming from the Spanish word "bajo" or low. The Bajío is filled with rolling hills and interrupted by the occasional chain of low mountains such as the Gavia and the Culiacán. Before the Spanish arrived, this area was covered in dense forests of holm oak and mesquite trees, but mining's need for wood fuel eventually cleared them. Today, the area is the center of most of

8037-461: Is wetter. The drier type is found in Abasolo, Irapuato, Salamanca and Romita . In total, these hot and relatively moist climates can be found in about 40% of the state. From the beginning of the colonial period, much of Guanajato's environment suffered greatly from the mining techniques and intensive agriculture the Spanish introduced. The process has been ongoing since then to modern times. Before

8208-449: Is worked into clothing, especially into coats, gloves, vests, scarves and other items for winter wear. Some of the workshops still work with large old weaving looms. In addition, there are workshops which make rugs, zarapes , and other items for the home. In Coroneo, the craft 100 years ago was practiced only by women. The most common item is still the zarape, which is decorated with figures such as horse heads and deer as well as fretwork on

8379-856: The Aguamilpa Dam begun in 1991 and the El Cajón Dam upstream from it. To provide irrigation water for farming the dry basin , the Nazas river was dammed in the 1930s and 1940s. This has led to the former drainage lakes in the area drying up, and soil depletion from the elimination of the river as a source of soil. Due to the continued logging in the area, erosion on the slopes of hillsides has increased. Numerous small populations live in Copper Canyon, some of them around old missions. Many settlements consist of single families or small family groups near agricultural fields. There are also

8550-644: The Chichimeca Jonaz and the Otomi , both of which are concentrated in the Valles de Sur area. Culturally, both groups show significant Purépecha influence. Both live in arid regions, where rainfall is precious and the diet includes foods such as pitayas , Myrtillocactus geometrizans (garambullo), cactus pear, nopal and agave . Hunting was an important source of protein but the scarcity of game has all but extinguished this practice. Subsistence agriculture forms

8721-664: The Grand Canyon . This plateau has an average elevation of 2,250 m (7,380 ft) with most of the more eroded canyons on the western slope, due to the higher moisture content. The highest elevations occur in the Tarahumara range. The exact elevations of the highest peaks are not known within accurate enough ranges to determine their relative elevation. The highest point is probably Cerro Mohinora , located at 25°57′N 107°03′W  /  25.950°N 107.050°W  / 25.950; -107.050 . Estimates for

8892-438: The Gulf of Mexico . On the western side of the mountains, which are affected by the largest change in precipitation between the dry season and monsoon season, in the monsoon season rainfall can exceed 300 mm (12 in) in a single month. The southern region receives more of the rainfall than the northern. Much of this precipitation occurs as tropical storms . As the high pressure over New Mexico breaks down, rainfall in

9063-741: The Nazas River and Aguanaval River drain the mountains into a closed basin. These mountains supply 90% of the water used for irrigation within the watershed. North of this system is the Conchos River which drains into the Rio Grande . Along many rivers the arid conditions have caused courses to be dammed to provide water for irrigation. These dams have caused concerns along with those caused by other activities. The Yaqui has been dammed with three large reservoirs along its course. The Río Grande de Santiago has also been dammed, including

9234-600: The Reform War . During this three-year period, the state would vacillate various times between the Liberals and Conservatives. In 1863, it was taken over by the French as they installed Maximilian I as emperor of Mexico. Maximillian did not reign long but the governor he appointed for Guanajuato, Florencio Antillón remained in Guanajuato until 1877. The situation stabilized over much of the government of Porfirio Díaz at

9405-618: The Sierra Madre del Sur and the Eje Volcánico Transversal (Transverse Volcanic Axis) of central Mexico after crossing 1,250 km (780 mi). The mountains range from 300 km (190 mi) from the Gulf of California in the north, but begin to approach within 50 km (30 mi) of the Pacific in the south. These mountains are generally considered to be part of the much larger American cordillera ,

9576-801: The War of Independence . Similarly, San Miguel has cultural and historical value. Both have been designated World Heritage Sites. Although not a World Heritage Site, Dolores Hidalgo is particularly important as the site as it is where Miguel Hidalgo y Costilla gave the cry called "El Grito" which began the War of Independence. The state has set up tourist routes such as the Ruta de Independencia, Ruta de Aventura (Aventure Route), Ruta Arqueológica (Archeological Route), Ruta de los Conventos (Monastery Route) and Ruta Artesanal (Handcrafts Route). The Ruta de la Independencia or Independence Route comprises ten municipalities through which

9747-639: The Yaqui River , which drains that area, is an important source of irrigation in the state of Sonora. The Yaqui drains into the Gulf of California , as do the Fuerte River in Sinaloa and the Humaya River further south. The Río Grande de Santiago drains 100,000 km (39,000 sq mi) from the southern slopes of the Sierra Madre. Along the more arid eastern slopes of the mountains,

9918-461: The conquest , the state was covered in forests, but mining requires large amounts of fuel to process minerals, so they were cut down for fuel and construction projects. Agriculture leached nutrients from the soil, caused erosion, and introduced plants, animals and diseases that have had a large impact. Today, the state contains 21 protected areas that extend over 63,611 hectares in 26 municipalities. These include Sierra de Lobos , Siete Luminarias ,

10089-428: The eastern cottontail , which lives in the forests of the western slopes, cliff chipmunk , rock squirrel , Mexican fox squirrel , and various species of Cricetidae . Raccoons , hog-nosed skunk , and hooded skunk live in the mountains. The white-nosed coati lives on the western slopes, and the ring-tailed cat lives throughout. Many species of bats live in the mountains also. A variety of lizards live in

10260-611: The "Western mother mountain range". To the east, from the Spanish oriental meaning "eastern" in English, the Sierra Madre Oriental range or "Eastern mother mountain range" runs generally parallel to the Sierra Madre Occidental along eastern Mexico and the Gulf of Mexico . The range extends from northern Sonora , a state near the Mexico–U.S. border at Arizona , southeast towards to the Trans-Mexican Volcanic Belt and Sierra Madre del Sur ranges. The high plateau that

10602-539: The 1980s, two of the state's cities, Guanajuato and San Miguel de Allende were declared World Heritage Sites . Today, the Bajio is one of the major grain producing regions in Mexico. The Guanajuato congress has asked for help against the theft of religious art in the state, which has the third highest incidence of such. One of the major occurrences was the theft of the gold crown of the Black Christ of Salamanca in 2010. The celebration of Mexico's Bicentennial

10773-477: The Catholic faith. However, the indigenous remained extremely marginalized and poor, losing both their language and their culture until most eventually intermarried with outsiders to produce mestizos . Through the Spanish colonial period, most of the area's wealth came from mining, with much of the agriculture springing up to support the mining communities. The height of mining came in the 18th century, mostly from

10944-596: The Cortes and Carborca Terranes is the San José de García Terrane, which is a combination of Cretaceous arc volcanics and volcaniclastics , which may be thrusting over the Cortes terrane. The southern part of the range is made up of the Guerrero Composite Terrane, a large body, which is actually a complex of five different subterranes, not all of them within the main body of the Sierra Madre. However,

11115-512: The Guanajuato area, led by Cristóbal de Olid in 1522, arrived in the Yuririhapúndaro and Pénjamo areas. The discovery of silver and gold in the area of the city of Guanajuato spurred Spanish settlement of the area in the 1520s and 1530s. Following the Spanish arrival, native tribes retreated to the most inaccessible areas of the Bajío and to the mountain ranges in the state, resisting the invaders, attacking settlements and travelers along

11286-486: The Museo del Vino y la Botellas (Museum of Spirits and Bottles). The museum contains a collection of about 3,000 bottles, almost all of which with their original contents. Nearby is the factory that makes the distinctive blue bottles of this brand. Glass making was brought to Mexico during the early colonial period. Most items made in Guanajuato are single-colored items in blue, green, yellow and red. San Miguel de Allende has

11457-665: The North, and a number of different accreted terranes , which are mostly covered by Cenozoic volcanism. The northern extent of the Sierra Madre is the Cortés Terrane, although the northern extreme of this contains a small portion of the Carborca Terrane. Some of the northern end may also be underlain by a Precambrian basement placed around the same time as the Grenville Orogeny . Some of this area has

11628-677: The Pacific Ocean and Gulf of Mexico as well as the major metropolitan areas of Monterrey , Mexico City and Guadalajara . In 2008, the total GDP for the state was US$ 38,204,000,000 (427,503,000,000 MXN) or 3.88% of the total for the country. From 2003 to 2008, the economy grew 1.06% (adjusted for inflation). The state has the sixth-largest economy in Mexico behind Mexico City, the State of Mexico , Nuevo León , Jalisco, and Veracruz . As of 2008, Guanajuato ranks fourth in per capita income at US$ 7,609, behind Mexico City, Nuevo León and Jalisco, with

11799-657: The Pacific. In addition to gold and silver and their related deposits, tin , iron , and mercury occur, sometimes in later units, mostly in later volcanics, and Molybdenum occurs in the mountains, often along with older copper deposits or in Oligocene deposits in the east. The belt of tin deposits lies mostly within the eastern slopes from Durango to Guanajuato. In these areas, tin occurs in rhyolitic ignimbrites in many, possibly over 1000, small deposits of cassiterite . Typically these deposits are divided from overlying ignimbrites by breccia, which may also contain ore. Many of these are thought to be hydrothermal deposits To

11970-489: The Sierra Gorda to the north, the Sierra de Guanajuato in the southeast, the Comanja in the northwest and the Codorniz in the east. The state is divided into five regions, taking into consideration geography and climate: Altos de Guanajuato, La Sierra Central, Bajío, La Sierra Gorda, and Los Valles del Sur. The Altos de Guanajuato, in the north, are a chain of forested mountains interspersed with pastures, small fields and areas with cacti and other desert plants. They begin near

12141-427: The Sierra Madre Occidental include tufted jay , the "gray-eared" subspecies of red warbler , eared quetzal , thick-billed parrot , and formerly included the imperial woodpecker , which now may be extinct. The rivers and streams of the range contain some of the southernmost trout populations in North America. These populations may be native, although this is not universally accepted. Invasive fish compete with

12312-405: The Sierra Madre ends. Because of the monsoon, the summer accounts for the majority of rainfall in the area. The spring and fall dry season separate out a weaker wet season in the winter. In addition to increasing in the southern ranges of the mountains, rainfall increases in the higher elevations of the Sierra Madre Occidental. Humidity in the mountains varies at wide levels as does rainfall. In

12483-454: The Sierra Madre from the central Mexican Plateau . The more southern one is the north–south Aguascalientes fault extending 150 kilometres (93 mi) from Altos de Jalisco to near Zacatecas, where it joins the more northern northwest–southeast trending San Luis–Tepehuanes fault extending from Guanajuato to Durango. The southern boundary of the Sierra Madre Occidental with the Jalisco block is

12654-537: The Silva Dam, Megaparque de Dolores Hidalgo, Cuenca de la Esperanza, Las Fuentes, Peña Alta, Pinal de Zamorano, Parque Metropolitano, La Joya Crater, Lake Yuriria , Las Musas, Culiacán and La Gavia Mountains, Sierra de los Agustinos , Sierra de Pénjamo , Cerro de Cubilete, Cerro de Amoles, La Purisima Dam, Arandas Mountain, La Soledad Dam, and the upper basin of the Temascatío River. Another protected area

12825-627: The Southern Cordilleran Basaltic Andesite Suite. The tuffs are above a thick formation of lava rock. Around five or six units have been identified, mostly around the Copper Canyon area. These tuffs have allowed wide-ranging correlation with formations in other geographical areas, for example Death Valley . During the Miocene, three periods of volcanism marked separate events in the Sierras. Each period

12996-466: The Spanish to negotiate peace with chiefs in exchange for basic goods such as blankets, clothes and food. This would bring temporary truces. Evangelization efforts would bring longer-term submission. Franciscans and Augustinians worked to gradually modify the worldview of the Chichimecas and others until many moved out of the mountains and into other settlements and professed, at least nominally,

13167-699: The Yuriria. Several of the Siete Luminarias craters have also developed crater lakes, especially La Joya, Parangueo and Olla de Zìntora. The most important river in Guanjuato and one of the most important in the country is the Lerma, along with its tributaries Guanajuato River , La Laja , and Turbio . The Lerma river basin covers 81% of the state (center and south); the Pánuco River basin (north of

13338-403: The activity of magmatism in the area, forming the first major igneous series in the area. The igneous series are made up of formations of plutonic and volcanic rock, which would later be exposed. Interbedded with these rocks are sedimentary deposit rocks. In the center of the range, some of these rocks have been deformed by tectonic forcing that occurred at the same time. The southern part of

13509-544: The animal may have been extirpated; the black bear population is small, and the Mexican grizzly bear that once resided here is confirmed extinct. Jaguars and ocelots are also now rare. On the other hand, mountain lion and bobcat are more common. On the eastern slopes there are American badger , coyote and gray fox that live across the mountains. Native ungulates include the white tailed deer , mule deer , and collared peccary . Rodents and lagomorphs include

13680-550: The area and surroundings. The Tarahumara frog lives in the oak and pine stands preferring moving water to pools. The southern extent of the Sonoran mountain kingsnake 's range is the Chihuahuan desert into the mountains. Other snakes and frogs live in the mountains, and many species live in the western slopes. Birds frequent the mountains, some as a migratory path and others as native species . The migratory birds often use

13851-426: The area around the city of Guanajuato. About 95% of the state's visitors are from Mexico, with the rest from other countries. Within the state, there are about seventy hotels ranked as four or five stars. The three main cities for tourism are the capital city of Guanajuato, San Miguel de Allende and Dolores Hidalgo. Guanajuato is visited for its colonial architecture and its role in Mexico's history, especially during

14022-450: The area have deposited ore veins that are commercially viable. The landscape was shaped after rock placement. Rivers cut valleys into the plateau, following folds in the rocks. Rocks have broken off of the slopes, forming rocky sides. The bedrock is covered by the clay rich soils, except in eroded areas, where water carries away deposits leaving a stony surface. The basement is thought to be Older North American basement, especially in

14193-522: The area is covered in tropical forest in which many plants lose leaves during the dry season from November to May. In the pre-Hispanic era, the Bajio saw the most human development due to the fertility of the soil and the presence of surface water for agriculture. The oldest group to inhabit the area were the people now known as the Chupícuarios, who dominated the center of the Bajío area and were active between 800 BCE and 300 CE. Their largest city

14364-472: The area that is likewise growing as a result of foreign investment. Being located in the center of the country has important economic implications for the state, as a number of major national highways and railways pass through. The state is also a center of industry with most of the state's major cities and economy located in the La Sierra Central and El Bajío regions. It has equal access to both

14535-442: The area to the west as an overwintering area, and migrate north along the western slopes. In the northern canyons birds may be divided into different habitats , or more specifically, the different types of forest, leading to differences in range by elevation. Some of this difference by elevation may even extend the range of some species, enabling tropical species to use the mountain valleys for migration. Bird species endemic to

14706-421: The area typically have large responses to the change in climate with each season. Monsoon season is the largest of these effects, with leaf buds following only a few months after the rains begin. Flowering season occurs in the months preceding the summer monsoon. This is only the peak flowering season, with plants flowering throughout the year. Due to the early flowering, fruit is ripe and seeds are dispersed at

14877-437: The area's population grow rapidly and eventually concentrate in urban centers. The area became an intendancy ( Spanish : intendencia ) or province in 1786, when the authorities divided New Spain into twelve parts. Despite the riches the area produced, most lived in oppression and poverty at the end of the 18th century, working on haciendas and in mines while a few, mostly European-born Spaniards, lived in opulence. Not only

15048-422: The area, by combining species from different regions. Animals typically associated with arid and mountainous habitats share the mountains with species associated with habitats further south. There are many carnivorous and omnivorous mammals native to the area, although several are extirpated or are part of threatened populations. The Mexican wolf 's range in the mountains is limited to the foothills of Durango or

15219-487: The average temperature is between 16 and 18 °C. Semiarid semihot climates can be found north of Dolores Hidalgo, around León and in areas near Celaya. In these municipalities, rainfall averages between 600 and 700 mm and the average annual temperature is between 18 and 20 °C. Temperate climates are judged by the presence of holm oak and pine forest, pine forests and/or pine forests with meadows. Humidity varies in these forest regions. Temperate semi-moist areas are mostly found in

15390-466: The basis of the economy and provides much of the current diet. However, these peoples are extremely poor, and many migrate to other places to find work. In what is now the state of Guanajuato, there were a number Nahua ) groups who built cities in the first millennium CE. but then abandoned them long before the arrival of the Spanish. It is believed that the Chichimeca came to dominate the area after

15561-589: The beginning of the Mexican War of Independence . This route begins at Dolores Hidalgo , and passes through the Sanctuary of Atotonilco , San Miguel de Allende , Celaya , and the capital of Guanajuato . Other important cities in the state include León , the state's biggest city, Salamanca , and Irapuato . The first town established by the Spaniards in Guanajuato is Acámbaro while the first to be named

15732-400: The beginning of the rains. There are also areas where plants have little response to the seasons, particularly those areas that experience moist conditions, caused by the elevations. These plants may maintain leaves through times when other areas are in the dry season, during which most deciduous trees have no leaves. The mountains are often a corridor for species allowing more diversity in

15903-434: The best-known tradition where curiously shaped bottles, vases, glass sets and small cups for tequila are produced. Wax candles and other items are a specialty in Salamanca, where they are especially in demand during Holy Week . Comonfort is known for the making of molcajetes from volcanic stone, and San Miguel is known for figures and other items made from brass. Dolores Hidalgo is known for ice cream and ices, much of which

16074-459: The border with San Luis Potosí, and extend south to Dolores Hidalgo, San Miguel de Allende, and the Querétaro border. This area's altitude varies from 1,800 meters to peaks over 2,900, such as La Giganta and La Sierra del Cubo. The climate is mostly semiarid with a rainy season in the summer, with average temperatures between 15 and 20 °C. Winter lows often reach 0 °C or lower with frosts. Wildlife

16245-639: The breakdown is usually at a slower pace than the movement north. This high pressure belt is associated with the mechanics that form the Bermuda High . The climate in the mountains is mild. Summer temperatures maintain a constant level. Maximum temperatures are typically in July at around 31 C with average temperatures of the order of 16 C during this same period. Mean annual temperatures are between 13–18 °C (55–65 °F) above 1,800 metres (6,000 ft). Below-freezing temperatures can occur in

16416-595: The canyon of the Santiago River. Near these sediments late Oligocene to early Miocene granite and granodiorite intrusive bodies occur. A possible cause of this is that these bodies were roof pendants which were uplifted by plutons . Mesozoic limestone also occurs in northern portion of the mountains, mostly from the Cretaceous. Towards the end of the Cretaceous , the Laramide orogeny increased

16587-520: The capital city. The site was marked by a giant Mexican flag flying alongside older historic flags, including a replica of the standard with an image of the Virgin of Guadalupe that Miguel Hidalgo carried as the insurgent banner. The Expo was housed in a series of pavilions which demonstrated the Mexican culture, history, traditions and customs. There were also pavilions hosted by various Latin American countries who also celebrated their Bicentennials around

16758-559: The central and southern areas of Mexico. Today, however, most children are not learning the language from their parents, putting it in danger of extinction in spite of efforts to introduce bilingual education. Concentrating in San Miguel de Allende, foreign residents from the United States and Canada came, in the early 2000s, because of the area's mild climate, cultural opportunities, and low crime rate. While accounting for only about ten percent of San Miguel's total population, they had

16929-426: The city is Cajetas La Tradicional, which has been in business for over 70 years. Metalworking can mostly be found in the communities of Guanajuato and Salamanca. Although the capital's mines no longer produce large quantities of gold and silver, silver items are still made and sold in the city. Wrought iron work for doors, windows and railings are also a specialty in certain areas of the city. Oxidized bronze items are

17100-479: The city of Guanajuato on 8 July 1821, declaring the entire state independent of Spanish rule. In 1824, Guanajuato was officially proclaimed a state of Mexico by the Constitutional Congress of Mexico. The years after the end of the War of Independence were extremely unstable, and would continue to be unstable through most of the rest of the 19th century. The towns of Dolores and San Miguel adopted

17271-491: The city of Guanajuato. The town's Spanish and Criollo populations took refuge in the heavily fortified Alhóndiga de Granaditas granary defended by Quartermaster Riaños. Hidalgo's army overwhelmed the defenses in two days and killed an estimated 400–600 men, women and children. Fighting associated with the War of Independence would return near the end of the conflict. Military commanders Luis de Cortázar and Anastasio Bustamante joined forces with Agustín de Iturbide and took

17442-545: The company acknowledged that part of the reason to build the plant was the existence of a General Motors plant in the same area as well as the existence of the Parque Industrial Puerto Interior which offers access to different transportation modes. The Centro de Innovación (Innovation Center) of Microsoft was inaugurated in 2010 in León. This establishment is meant to support businesses and governments to form software and technology enterprises with

17613-414: The craters. La Alberca ("The Pool") is a crater lake open to the public for swimming, rowing or boating. The name of Siete Luminarias ("Seven Lanterns") comes from an imagined prehistoric time when the seven were active at once. The state has about 1,500 bodies of surface water, along with underground aquifers in most parts of the state. Its principal lake is Lake Cuitzeo , on the border with Michoacán and

17784-643: The early flows. Fissure-vein deposits have been divided into two groups of fissure vein deposits, which are divided geographically into an eastern and western series. In the east, the gold and silver are accompanied by lead and zinc . In the south, the Bolaños mine district is contained with the Bolaños Graben. Some also occur as epithermal deposits. Also, some gold occurs along with copper in Cenozoic iron-oxide skarn and replacement deposits along

17955-460: The early morning before dawn, the air is almost saturated (often over 90% relative humidity ) near the mountain tops with low clouds over the range. Lower in the range, air is not as near saturated in the morning. Seasonal variation in humidity is also present with average May and June relative humidity around 50%, with 25% possible during the day. Also during the day, relative humidity drops and cloud levels rise as temperatures rise. The humidity of

18126-621: The east of these units is a belt of more mercury deposits, followed by another belt of manganese deposits, although these deposits are mostly limited to Chihuahua and Hidalgo. Iron occurs in three different regions placed by different mechanisms. Along the Pacific there the numerous skarn and replacement deposits mentioned above with relation to gold. Iron occurs in Durango in the form of magnetite lava flows, which are often surrounded by smaller hematite deposits, thought to be ash flows. There

18297-404: The eastern slopes have increased organic content and a clay heavy layer that is developed more than those of the more arid eastern lands. The thickness of soil layers also increases. Problems with soil degradation have been aggravated by the cultivation of drug crops, leading to deforestation of many areas. Other problems include overgrazing , which has led to terracing from cattle paths and

18468-498: The economically important and densely populated province of Guanajuato. One of Hidalgo's first stops was at the Sanctuary of Atotonilco . There, Hidalgo affixed an image of the Virgin to a lance to adopt it as his banner. He then inscribed the following slogans on his troops' flags: "Long live religion! Long live our most Holy Mother of Guadalupe! Long live Ferdinand VII ! Long live America and death to bad government!" The extent and

18639-528: The edges. However, sweaters, capes, rebozos , bags and even wool shoes can also be found for sale. One other specialty is rugs woven on large looms. Apaseo el Alto is known for its work in fine woods, which began with the workshop of Domingo Garcia sixty years ago. Since then, about 150 workshops have been established in the municipality, employing about 500 craftsmen. Items include sculptures such as religious figures and animals and utilitarian items such as utensils and furniture. Craftsmen first began working with

18810-452: The end of the 19th century and the economy improved, but the Diaz government was oppressive. Diaz installed Francisco Mena as governor of the state, who made a fortune through the concession of railway lines which were being built to modernize the country. Even though slavery was officially abolished during the War of Independence, most laborers in farms and mines were extremely underpaid and in

18981-684: The fall of these cities, and the Chichimeca Jonaz believe that the eagle, which is sacred to them, led them here. At the time of the Spanish conquest, the only Chichimeca group left were the Chichimeca Jonaz, who were semi-nomadic and warlike. These qualities allowed these Chichimecas to resist Spanish domination for many years. However, the deterioration of the environment by the Spanish depleted resources for these people and finally made them submit. The Chichimeca Jonaz refer to themselves and other indigenous as "uza" (singular) or "ézar" (plural), which roughly translates to "Indian". Their language

19152-524: The federal government declared the Sierra Gorda region in Querétaro a Biosphere Reserve, with Guanajuato's portion added in 2007. On the Guanajuato side, it covers 236,882 hectares over the municipalities of Xichú, San Luis de la Paz , Atarjea , Victoria and Santa Catarina . Culturally, the Sierra Gorda region is the far western part of La Huasteca , which extends over parts of Querétaro, San Luis Potosí, Hidalgo and Veracruz . The Sierra Central

19323-422: The formation of a soil crust , and soil acidification , which poses a risk to some grasslands as of 2002. The climate varies considerably between the northern and southern extents of this long mountain range. Seasonal variations also occur due to the presence of large bodies of warm water delivering warm damp air from each side of the range. This region undergoes a seasonal variety with two wet seasons, including

19494-406: The ghost towns is Mineral de Pozos in the northeast of the state. The town still has its cobblestone streets with names such as Relámpago (lightning), Estrellas (stars) and Flores (Flowers). The houses here are abandoned, many in ruins and none with roofs. The town reached its height during the late 19th and early 20th centuries, when it was called Ciudad Porfirio Díaz, but the mines later gave out and

19665-426: The goal of starting fifty new businesses with ten to twenty employees each. Almost all handcrafts (98%) are made in micro and small enterprises, most of which are family-owned. Almost all them, which mostly consist of glass, wrought iron, ceramic and wooden items, are exported to the United States (91%). However, craft items are under pressure from imitations from Central America and Asia. The crafts sector of industry

19836-554: The government by a group called the Sinarquistas occurred in Leon. However, most of the state was peaceful most of the time, allowing the economy to recover. This was especially true of the agricultural sector, producing wheat, corn, sorghum, alfalfa, strawberries in Irapuato and goats in various parts. Goat milk cajeta candy from Celaya is known in most of Mexico. The first Festival Internacional Cervantino occurred in 1972. In

20007-609: The height of the mountain start around 3,040 m (9,970 ft) and go up to 3,300 m (10,800 ft). However, Cerro Barajas, at 26°24′N 106°5′W  /  26.400°N 106.083°W  / 26.400; -106.083 , may be as high as 3,300 m (10,800 ft) although other sources give 3,170 m (10,400 ft) as the elevation. Cerro Gordo, at 23°12′N 104°57′W  /  23.200°N 104.950°W  / 23.200; -104.950 , may have an elevation between 3,350 m (10,990 ft) and 3,340 m (10,960 ft). The southern end of

20178-488: The higher elevations, there are forests of pine and holm oak but these have been much reduced by deforestation. The more arid areas have mesquite, nopal and other desert plants. There are several small lakes, the best known being Lake Yuriria as well as canyons and cave systems, some of which were used for ceremonial purposes by pre-Hispanic peoples. It is also the home the Siete Luminarias de Valle de Santiago,

20349-471: The higher mountains, with precipitation occurring as snowfall certain times of year. During the summer monsoon, wind patterns undergo large-scale changes. In May there is very little large-scale wind current through the mountains, most circulates around the mountains, although onshore flow is present. As the high pressure moves north, air is pulled off the Gulf of Mexico, bringing easterly winds aloft to

20520-883: The indigenous, mestizo and Negro slaves were having problems with the social order. Many Criollos or New World-born Spanish were marginalized by the Spain-born. One of the first rebellions against colonial rule came in 1766, when a group attacked the Caja Real in Guanajuato city to protest high taxes. In 1767, there were protests against the expulsion of the Jesuits by the Spanish Crown . These were put down with extreme force, but they spurred conspiracies, and groups organizing against colonial rule, especially in San Miguel el Grande and León. Numerous plans were made, but few were carried out or had impact until 1809. In that year,

20691-613: The insurgent army under Miguel Hidalgo passed. These include San Miguel de Allende, Dolores Hidalgo, Guanajuato, León, Irapuato, Pénjamo, Salamanca, Celaya, Salvatierra and Acámbaro. In preparation for the Bicentennial of Mexico's independence, the state rehabilitated and marked the sites in which the significant historic events occurred in each of these locations. The Ruta de Aventura connects ghost towns and abandoned mines with natural areas for hiking, mountain biking and ATV as well as other extreme sports such as paragliding . One of

20862-468: The intensity of the movement took viceregal authorities by surprise. San Miguel and Celaya were captured with little resistance. On 21 September 1810, Hidalgo was proclaimed general and supreme commander after arriving at Celaya. At this point, Hidalgo's army numbered about 50,000. However, due to lack of military discipline, the insurgents soon fell into robbing, looting and ransacking the towns they were capturing. On 28 September 1810 , Hidalgo arrived at

21033-465: The interior basins . These faults are commonly covered by alluvium and basalt , making them difficult to discern, but can be found in certain fault blocks . Grabens have formed in the north, and some of these are filled with volcanic and sedimentary floors, and long depressions have formed in the southern Sierra Madre. The faulting decreases in the center of the range where the faults are mostly small normal faults , but increases once again on

21204-438: The mainstays of the state's economy, but have since been eclipsed by the secondary sector . Guanajuato has particularly seen growth in the automotive industry . The name Guanajuato comes from Purépecha kuanhasï juáta (or in older orthography "quanax huato"), which means "frog hill". Guanajuato is in the center of Mexico, northwest of Mexico City, bordering Zacatecas, San Luis Potosí, Michoacán, Querétaro, and Jalisco. It

21375-562: The middle, an arc of andesite was placed during the spreading of the Gulf of California . The basin and range-style faulting of the middle-late Miocene took place at the same time as the placement of alkali basalts , In the westernmost slopes mafic dikes formed. These events have also been linked to the subduction of the Farallon Plate . Episodes of volcanism continued into the Quaternary . The Sierras are believed to be

21546-409: The mines in the hills around the city of Guanajuato, leading to the construction of a large number of notable civil and religious buildings in the same area. The extremely fertile Bajío area became a major agricultural area for New Spain . Both mining and agriculture brought in more Spanish and Criollos to take advantage, as well as mestizos and some African slaves to work the mines and fields, making

21717-539: The monsoon season. Precipitation varies on both annual and seasonal scales in the Sierra Madre. Annual differences in regional climate are associated with the El Niño-Southern Oscillation with El Niño years leading to a wetter climate. Monsoon rains come to the Sierra Madre in June as the high pressure area moves north, leading to wet summer seasons. This causes east winds bringing moisture from

21888-471: The most humidity are in Santa Rosa and municipality of Guanajuato. These have rainfall averages over 800 mm and average temperatures under 16 °C. Hot and moist climates in the state have temperatures ranging from 18 to 22 °C and are associated with tropical rainforest, with some grassland. These climates are subdivided into two types, one that receives less rainfall with a significant dry season and one that

22059-501: The mountains extending from Alaska down to these across western North America. Sierra Tarahumara or Tarahumara is the name for the region of the Sierra Madre beginning at the Durango border and extending north. This name comes from the Tarahumara natives. This is a dramatic landscape of steep mountains formed by a high plateau that has been cut through with canyons including Copper Canyon , larger and, in places, deeper than

22230-652: The mountains may be referred to as the Sierra Huichola. In this area, the Sierra Madre begins to give way to the Basin and Range Province . Subranges of this area include the Sierra de Alica and the Sierra Pajaritos , both in Nayarit, and the Sierra los Huicholes , Sierra de Morones , Sierra Nochistlán, and Sierra Fría extending eastwards into Jalisco, Zacatecas, and Aguascalientes. The mountains act as

22401-417: The mountains. On the east slope of the mountain, daytime upslope winds flow to the crest, where the flow joins westerly winds. The mountains cause convection during the following monsoon season, during which nocturnal winds at low levels in the atmosphere move moisture overnight. Extensive lightning activity occurs during this season. After the high pressure breaks down, wind patterns return to those prior to

22572-487: The municipalities of Valle de Santiago , Yuriria , Tarimoro , Apaseo el Alto , Moroleón , Uriangato , Santiago Maravatío , Acámbaro , Jerécuaro , Coroneo and Tarandacuao . The area is part of the Trans-Mexican Volcanic Belt, with elevations ranging between 1,700 and 2,000 meters. The soil is fertile due to its volcanic base, producing crops such as sorghum , wheat, corn and vegetables. The land also produces building materials such as tezontle and black sandstone. In

22743-498: The names of Dolores Hidalgo and San Miguel de Allende in honor of those who began the independence movement and in 1826, the first constitution of the state of Guanajuato was adopted. Like much of the rest of the country, Guanajuato was affected by the prolonged fighting between Liberal and Conservative factions as well as the foreign incursions that dominated the 19th century. Guanajuato's status vacillated between state (when Liberals were in charge) and department (when Conservatives held

22914-634: The native population's opposition to these practices. The range trends from the north to southeast. Canyons cut by the rivers of the wet western slopes exist in addition to those of the northeast slopes, notably the Copper Canyon . The range runs parallel to the Pacific coast of Mexico, from just south of the Arizona-Sonora border southeast through eastern Sonora , western Chihuahua , Sinaloa , Durango , Zacatecas , Nayarit , Jalisco , Aguascalientes to Guanajuato , where it joins with

23085-539: The native species which has been a cause of concern among researchers, along with concerns about the effects of logging on these species. The Sonoran Desert is found in the northwestern foothills at 1,000–2,000 m (3,300–6,600 ft). The Chihuahuan Desert is found to the northeast and east, the Meseta Central matorral and Central Mexican matorral to the southeast, and the Sinaloan dry forests to

23256-653: The northeast. The Mexican Plateau extends through the center of the state. It is subdivided into various regions parted by low-lying mountain chains such as the Sierra de la Cuatralba and the Sierra de Cubo. The Trans Mexican Volcanic Belt crosses the state in the south and includes the Bajío area, the Altos de Jalisco and the valleys area in the far south. The state is crossed by several mountain ranges with mountains between 2,300 and 3,000 meters high. Mountain ranges average 2,305 meters and flat areas lie at around 1,725 meters above mean sea level. Other important mountain ranges include

23427-543: The population left. In 1982, the town was declared a Historic Monument Zone. Although no one lives there, tourism keeps a few businesses alive around the main square such as the Pozos cantina, which exhibits photographs and other memorabilia on its walls. Outside the town is the Santa Brigida mine which sustained the town until it gave out. It is marked by three large ovens with tall pyramid roofs. These were constructed by

23598-488: The population professes the Catholic religion, and the state is considered to be very conservative and adherent to Catholic principles both socially and politically. Guanajuato has the fourth lowest number of people who can speak an indigenous language. However, the ethnically indigenous population is about 10,347 (2005) or 2.6% of the population over the age of five. The languages spoken are Chichimeca Jonaz , Otomi and Nahuatl . The two most important indigenous groups are

23769-401: The range are the major determining factors in the dominant plants. Oaks dominate the lower reaches of the mountains, where stands grow down to about 1,000 m (3,300 ft). Some oak species even continue into the surrounding ecosystems. In the western slopes of the range, cloud forest also occurs, mostly on mid-elevation slopes with little exposure to wind or sun in the southern end of

23940-519: The range contains none of the volcanism that is apparent in the northern range. These formations ended in the Paleocene . Eocene volcanism formed a series of andesitic and rhyolitic formations in the area, with spatial and temporal variations throughout. Most of the gold and silver deposits are also in these rocks. In the Oligocene, ash flows became the predominant deposit of the area, with interbedded lava flows between. These ash flows began

24111-525: The range is also influenced by the same seasonal changes as rainfall. In the dry season dew points are low at high elevations (500 hPa), around −22 °C (−8 °F) in the south of the range, and −24 and −26 °C (−11 and −15 °F) in the north in May. In June, dew points begin to increase from the May levels up to −20 °C (−4 °F) in the north and −16 °C (3 °F) in the south. By July these dew points are at −14 °C (7 °F) throughout

24282-424: The range, but the forests in the mountains vary by elevation and place in the range. This ecoregion is noted for its high biodiversity and large number of endemic species, and for allowing some species to extend their range . The dominant plants vary across the range, and the habitat that they present varies from scattered woodland to both deciduous and coniferous forest. The elevation and latitude in

24453-442: The range. At higher elevations pines begin to grow alongside the oaks, and pines begin to dominate the oaks at higher elevations. At high elevations and in the north, mixed conifer forests become the dominant ecosystem. These forests are composed primarily of pines and firs , which begin to grow at these elevations. There are also grasslands on some mountain tops, surrounded by the forest that occur in those areas. Plants in

24624-405: The range. The range allows higher dew points throughout these periods than the surrounding low lands. This rise in humidity accompanies the monsoon. The mountains create a diverse setting for plants and animals by creating a different set of conditions from the surroundings. The Sierra Madre Occidental pine-oak forests are found at elevations of 1,500–3,000 m (4,900–9,800 ft) throughout

24795-415: The rock that is most visible to be ignimbrites with lava flow layers. The region has a general strike from just west of north to just south of east. Faults in the area tend to be younger than the upper volcanics, excluding those associated with calderas, but do occur in distinct periods. The large faults along the eastern slope have caused the slope to be made up of large escarpments that face into

24966-511: The routes that connected Spanish settlements and mining camps. The Spanish were unable to force the natives of this area (unlike the more settled indigenous peoples ) to work, and brought African slaves and indigenous peoples from other areas to work the haciendas and mines. The colonization efforts in the eastern part of the state began in 1542 when Spanish land-grants were issued for the Apaseo and Chamácuaro areas. In 1555 San Miguel el Grande

25137-491: The same name . The municipality has an area of 7,238.4 km (2,794.8 sq mi). During the past few years, the city's infrastructure has improved vastly. Agriculture is a vital part of the city's economy.

Religion in Guanajuato (2010) As of 2005, the state had a population of 4,893,812, which is the sixth largest population in Mexico. About 67% live in urban areas, with the rest in rural areas, and women slightly outnumbering men. The largest population centers are León with 1,134,842 people, Irapuato with 440,134, Celaya with 382,958, and Salamanca with 226,654. Over 94% of

25479-435: The second series of high magmatism formations. The Mid-Tertiary ignimbrite flare-up formed a series of ignimbrite formations, layered one atop another, that are sometimes broken by lava flows. The ignimbrite formations in this area cover the largest area of any known series, with ten calderas identified in the province. Three of these calderas are in Copper Canyon. The lava has formed a series of mafic rocks that comprise

25650-460: The sector is an important part of the state's identity and is still a major producer of a number of items nationally. The state has 1.1 million hectares suitable for agriculture, over 36% of the state's territory. Over 659,000 hectares (1,630,000 acres) of land is under cultivation, with the main crops being corn, sorghum, beans, wheat, barley and broccoli. Today, the Bajio is still one of the major grain producing regions in Mexico. Certain areas of

25821-465: The soil help reduce runoff and soil losses from erosion. Areas that are covered in stone are known as lithosols , and make up most of the remaining surface in the mountains, especially on upper slopes. The last major soil type are vertisols , which are thin mineral-poor soils. Soils at higher elevations experience more leaching , due to increased rainfall. Acidic soils may have lower calcium content, leading to lower plant soil quality . Soils along

25992-504: The southeast municipalities of Apaseo, Coroneo and Jerécuaro and in the center of the state. Precipitation varies from 600 to 700 mm and the average temperature is between 16 and 18 °C. Temperate and somewhat humid climates have rainfall averages of between 700 and 800 mm, with temperatures between 16 and 18 °C. These can be found in Pénjamo , Coroneo, Jerécuaro and parts of Guanajuato (municipality) and Dolores Hidalgo. Temperate climates with

26163-572: The southern valleys, and Aztecs had ventured into the area looking for minerals. However, most of the state was dominated by various Chichimeca tribes as part of what the Spanish would call the "Gran Chichimeca". These Chichimeca were mostly nomadic with some scattered agricultural communities, mostly in the north. As the area of Guanajuato lies on the boundary of the arid north of Mexico, at first relatively few Spanish came to settle - as opposed to points south, which had much more abundant rainfall and indigenous labor. The first Spanish expedition to visit

26334-553: The state are concentrated in the community of Cieneguilla in the municipality of Tierra Blanca . In pre-Hispanic times, these people were semi-nomadic, desert dwellers. During the Conquest, these and other Otomi groups allied themselves with the Spanish, in part because the Aztecs and others considered the Otomi to be backwards and barbaric. The Otomi also speak an Oto-Pamean language and are related to other Otomi groups scattered around

26505-423: The state capital, but they were defeated and Doméco was executed by firing squad. In 1855, Conservative Manuel Doblado, then the governor of Guanajuato, forced Juan Álvarez out of the presidency after he took power from Antonio López de Santa Anna . In 1858, the government under President Benito Juárez moved from Mexico City to the city of Guanajuato before moving again to Manzanillo and then Veracruz during

26676-599: The state fought and died in other parts of Mexico, leaving behind widows and children. After the war, the large landholdings were broken up and land redistributed into ejidos , or commonly held land, which benefitted many rural families. After the end of the Mexican Revolution, fighting in Mexico continues with the Cristero War . Fighting related to this was most prominent in Pénjamo and León, but occurred in other areas as well. In 1946, an uprising against

Livestock raising is an important economic activity and can be found in all parts of the state, with animals such cattle, pigs, goats, sheep and domestic fowl, with 1,451,478 hectares (3,586,680 acres) hectares dedicated to this activity. The Los Altos and Bajío are

27018-455: The state is that of the city of Guanajuato, as granted by Carlos I of Spain ( r.  1516–1556 ). In 1590 the Villa de San Luis de la Paz was founded and named after the peace ( paz ) treaty between the Spanish and the Chichimeca. With the Spanish occupying most of the most productive land and its resources, the indigenous of the area became extremely impoverished. This eventually allowed

27189-621: The state was also inhabited by the Otomi but they were mostly displaced or dominated by the Purépecha in the southwest and the Chichimeca in other parts. By the 16th century, most of Mesoamerica was dominated by either the Aztec Empire or Purépecha Empire , but Guanajuato was under the control of neither. It was on the northern border of the Purépecha Empire with southern Guanajuato showing significant cultural influence in

27360-473: The state's agriculture and industry since the terrain allows for highways and large farms, which produce grains, vegetables and fruit. This farmland is considered some of Mexico's most productive. Los Valles del Sur, also called the Valles Abajeños, are valleys located in southwestern Guanajuato, bordering Michoacán. This area is distinguished by the large number of Purépecha place names and covers

27531-401: The state's livestock producing regions, especially dairy cows. It is one of the most important dairy producing states in Mexico. By volume, most of the meat produced is from domestic fowl, with pork coming in second, followed by beef, goat and sheep. Guanajuato produces 25.4% of the goat meat in the country. Only a very small percentage of the economy is based on fishing and forestry. Fishing

27702-482: The state) and Cuitzeo Lake cover the remainder. The Lerma is regulated by various dams in part to control the fact that it ran very high in the rainy season and very low in the dry season. These dams include the Ignacio Allende, la Purísima, Solís, La Gavia, Conejo II and Santa Ifigenia. Climates in the state are grouped by precipitation and average temperatures into three major groups. The semiarid climate

27873-580: The state. Twenty-seven of 46 municipalities have a high level of migration out to other areas, with 19 having a moderate to low level of the same. The annual rate of migration to the United States is 7.07 people per thousand. Industry is the most important segment in the modern state economy, accounting for about 30%. Most of this is the production of automobiles and automobile parts, pharmaceuticals and other modern items. It also includes more traditional items such as processed foods (cheese, canned items and more) as well as shoes and other leather goods in León and

28044-607: The terrane is mostly covered by volcanics and sedimentary deposits, so it is only visible where erosion has revealed it. The main subterranes of the Guerrero Composite Terrane that are within the Sierra Madre are the Tahue and Zihuatanejo terranes. Dividing the Guerrero Terrane from the rest of the Sierra Madre terranes is a boundary that is thought to represent the Early Cretaceous Arperos Basin,

These lower elevations are usually graded into by a stand of tropical deciduous forest , which has a large portion of flora made up of flowering plants and legumes . These flowering plants are mostly from the genus Bursera . The ecotone , made up of the tropical deciduous forest, is commonly sparsely populated, sometimes only by small stands of trees. It may be referred to as savanna . Guanajuato It

28557-614: The western boundary of the faults in the southern mountains. In the north there is an unknown boundary between the Cortes Terrane and the Guerrero Composite Terrane. Some theorize that this is a section of the Mojave–Sonora Megashear, but this theory is not universally accepted; however, the Megashear is important, and, in fact, is necessary for reconstructions of the opening of the Gulf of California, as of 2003. On

28728-410: The western slope. In fact, the major normal faults tend to diverge around the center of the core and join at either end. Some of these faults may have allowed ignimbrites to erupt from the surface, and so there may be some association between the ignimbrite occurrence and faults; this can be used to find out information about different kinds of basement rock present. There are two faults dividing

28899-478: The work through its Centro Turistico de Desarrollo de Tarandacuao. Acámbaro is noted for its bread. One local bread specialty is the tallado , which has a base of egg and butter and can have fillings such as fig , coconut, raisins and chocolate. This bread is the result of recipes brought by the Franciscans , modified over time by the native indigenous potters’ community. San Francisco del Rincón has had

29070-554: Was founded to protect roads linking mining camps and cities with Mexico City to the south-east. The Villa de León was founded in 1576 to counter attacks by the indigenous peoples. But through the first centuries of the colonial period, the city of Guanajuato dominated because of its mines. The official name of the state is Guanajuato, Estado Libre y Soberano (Guanajuato, Free and Sovereign State). "Guanajuato" comes from Purépecha Quanaxhuato , which has been translated as both "place of frogs" and "places of many hills". The coat of arms of
