Of the states of which at least a portion make up the Southwest, Texas was the first to achieve statehood. On December 29, 1845, the Republic of Texas was annexed, bypassing the status of becoming a territory, and immediately became a state. Initially, its borders included parts of what would become several other states: almost half of New Mexico,
6669-582: The Homestead Acts in 1862 accelerated settlement and agricultural development in the state. After the Civil War, many veterans constructed homesteads in Kansas. Many African Americans also looked to Kansas as the land of " John Brown " and, led by freedmen like Benjamin "Pap" Singleton , began establishing black colonies in the state. Leaving southern states in the late 1870s because of increasing discrimination, they became known as Exodusters . At

When it was officially opened to settlement by the U.S. government in 1854 with the Kansas–Nebraska Act , conflict between abolitionist Free-Staters from New England and pro-slavery settlers from neighboring Missouri broke out over the question of whether Kansas would become a free state or a slave state , in a period known as Bleeding Kansas . On January 29, 1861, Kansas entered
8550-407: The 1930s and 1940s, many definitions of the Southwest included all or part of Texas, Oklahoma, New Mexico, Arizona, California, Colorado, and Utah. As time has gone on, the definition of the Southwest has become more solidified and more compact. For example, in 1948 the National Geographic Society defined the American Southwest as all of California, Nevada, Utah, Arizona, Colorado, and New Mexico, and
8721-477: The American Southwest as parts of Arizona, Colorado, Kansas, New Mexico, Oklahoma, Texas, and Utah. From this perspective, almost all of the region's physiographical traits, geological formations, and weather are contained within a box between 26° and 38° northern latitude, and 98° 30' and 124° western longitude. When looking at the fauna of the region, there is a broader definition of the American Southwest. The Southwestern Center for Herpetological Research defines

#17327653138118892-404: The Ancestral Pueblo people, also known as the "Anasazi" (although that term is viewed by modern Pueblo people as derogatory and is becoming more and more disused), began settling in the area in approximately 1500 BC. Eventually, they would spread throughout the entire northern section of the Southwest. This culture would go through several different eras lasting from approximately 1500 BC through
9063-441: The Ancestral Puebloans, while the Akimel O'odham and Tohono O'odham claim descent from Hohokam. The area previously occupied by the Mogollon was taken over by an unrelated tribe, the Apache . While it is unclear whether any of the modern Indian tribes are descended from the Mogollon, some archeologists and historians believe that they mixed with Ancestral Puebloans and became part of the modern Hopi and Zuni tribes. Prior to

His application to that body for a commission was flatly rejected due to his pre-war criminal record. Passage of
9747-428: The Colorado border, in Wallace County . It is a common misconception that Kansas is the flattest state in the nation—in 2003, a tongue-in-cheek study famously declared the state "flatter than a pancake". In fact, Kansas has a maximum topographic relief of 3,360 ft (1,020 m), making it the 23rd flattest U.S. state measured by maximum relief. Around 74 mi (119 km) of the state's northeastern boundary

12483-538: The Old West, the Gunfight at the O.K. Corral . Copper was also discovered in 1877, near Bisbee and Jerome in Arizona, which became an important component of the economy of the Southwest. Production began in 1880 and was made more profitable by the expansion of the railroad throughout the territory during the 1880s. The early 1880s also saw the completion of the second transcontinental railroad, which ran through
12654-858: The Pacific and Atlantic oceans. The geographic center of the 48 contiguous states is in Smith County near Lebanon . Until 1989, the Meades Ranch Triangulation Station in Osborne County was the geodetic center of North America: the central reference point for all maps of North America. The geographic center of Kansas is in Barton County . Kansas is underlain by a sequence of horizontal to gently westward dipping sedimentary rocks . A sequence of Mississippian , Pennsylvanian and Permian rocks outcrop in
12825-563: The Parry saltbush and the Mojave sage, both only found in the Mojave, as well as the creosote bush. The Colorado Plateau varies from the large stands of forests in the west, including the largest stand of ponderosa pine trees in the world, to the Mesas to the east. Although not called a desert, the Colorado Plateau is mostly made up of high desert. Within the Southwest U.S. region, the Colorado
12996-702: The Pecos, north of the [Mexican] Border, south of the Mesa Verde and the Grand Canyon, and east of the mountains which wall off Southern California and make it a land in itself." Texas has long been the focal point of this dichotomy, and is often considered, as such, the core area of "the South's Southwest." While the Trans-Pecos area is generally acknowledged as part of the desert Southwest , most of Texas and large parts of Oklahoma are often placed into
13167-500: The Plains states as well as in parts of the mountainous west. The predominant shales and mudstones are a source of hydrocarbons while the lenses and channels of sandstone form exploitable hydrocarbon reserves. Thus, the Dakota Group is an oil and gas source in the Denver Basin . When they are near the surface, these same structures function as aquitards and aquifers , respectively. The Dakota sandstones form crucial supplies of water on
13338-505: The Plains, especially on uplands between river valleys wherever it is found outside the boundaries of the Ogallala Aquifer . As the formation is uniquely terrestrial in origin, in contrast to the vast marine formations of the Plains, the Dakota has additional unique resources. Lignite coal has formed in the unit and was mined briefly in the 19th century. This supply was immediately mined for fuel by early American settlers, but
13509-654: The Plateau, which includes spectacular lava formations, "painted" deserts, sand dunes, and badlands. One of the most distinctive features of the Plateau is its longevity, having come into existence at least 500 million years ago. The Plateau can be divided into six sections, three of which fall into the Southwest region. Beginning with the Navajo section forming the northern boundary of the Southwestern United States, which has shallower canyons than those in
13680-549: The Provincia de las Californias, creating the province Alta California , which consisted primarily of what would become California, Nevada, Arizona, Colorado, Utah and New Mexico. In 1821 Mexico achieved its independence from Spain and shortly after, in 1824, developed its constitution , which established the Alta California territory, which was the same geographic area as the earlier Spanish province. In 1825, Arizona
13851-510: The Rio Grande into the Trans-Pecos region of Texas. The fourth subregion Meinig calls the "Northern Corridor and Navajolands," a major highway and railway trunk which connects Albuquerque and Flagstaff . Just north of the transportation trunk are large blocks of American Indian land. As the US expanded westward , the country's western border also shifted westward, and consequently, so did
14022-543: The Sonora Desert which lies in the Southwestern United States is the most populated area within the region. Six of the top ten major population centers of the region are found within its borders: Phoenix, Tucson , Mesa , Chandler , Glendale , and Scottsdale , all in Arizona. Also within its borders are Yuma and Prescott, Arizona . The most northwest portion of the American Southwest is covered by
14193-458: The Sonoran Desert to the west. The Chihuahuan Desert spreads across the southeastern portion of the region, covering from southeastern Arizona, across southern New Mexico, and the portion of western Texas included in the Southwest. While it is the second largest desert in the United States, only a third of the desert is within the United States, with the rest in Mexico. El Paso and Albuquerque are
14364-616: The South Platte Formation. In eastern Utah and western Colorado, Young introduced the term Naturita Formation for a series of facies in the larger "Dakota Group". However, despite Witzke and Ludvigson logic, geologist have continued to refer to the Lower Cretaceous sequence of formations on the Colorado Plateau and the Rocky Mountains as the Dakota Group. The Dakota has provided several resources in
14535-410: The Southwest as being only the states of Arizona, New Mexico, with parts of California, Nevada, Texas, and Utah; although they include all of those six states in their map of the region, solely for ease of defining the border. Lawrence Clark Powell, a major bibliographer whose emphasis is on the Southwest, defined the American Southwest in a 1958 Arizona Highways article as, "the lands lying west of
14706-601: The Southwest became embroiled in the Mexican–American War , partly as a result of the United States' annexation of Texas. On August 18, 1846, an American force captured Santa Fe, New Mexico. On December 16 of the same year, American forces captured Tucson, Arizona, marking the end of hostilities in the Southwest United States. When the war ended with the Treaty of Guadalupe Hidalgo on February 2, 1848,
14877-509: The Southwest began to decline for unknown reasons, although severe drought and encroachment from other peoples have been postulated. By the end of the 15th century, all three cultures had disappeared. The modern Puebloan tribes of the Isleta , Sandia , Cochiti , Kewa , Santa Ana , Taos , Jemez , Acoma , Laguna , and Zia , as well as the Hopi and Zuni peoples , trace their ancestry back to
15048-600: The Southwest in a very similar fashion to Reed: the portion of New Mexico west of the Llano Estacado and the portion of Arizona east of the Mojave - Sonoran Desert and south of the "canyon lands" and also including the El Paso district of western Texas and the southernmost part of Colorado. Meinig breaks the Southwest down into four distinct subregions. He calls the first subregion " Northern New Mexico ," and describes it as focused on Albuquerque and Santa Fe . It extends from
15219-554: The Southwest. Around AD 1100 their culture began to develop in the Four Corners area of the region. The Navajos migrated from northwestern Canada and eastern Alaska , where the majority of Athabaskan speakers reside. The Ute were found over most of modern-day Utah and Colorado, as well as northern New Mexico and Arizona. The Paiutes roamed an area which covered over 45,000 square miles of southern Nevada and California, south-central Utah, and northern Arizona. The Hopi settled
15390-763: The Twowells Sandstone Tongue of the Dakota Sandstone. In the western San Juan Basin, the lowermost part of the Dakota Sandstone, although of marginal marine origin in the eastern San Juan Basin, is a complex of non-marine sandstones. These relationships are especially well displayed in the San Juan Basin of northwestern New Mexico Beginning in the Early Cretaceous, the Cretaceous Seaway spread south from what
15561-446: The United States gained control of all of present-day California, Nevada and Utah, as well as the majority of Arizona, and parts of New Mexico and Colorado (the rest of present-day Colorado, and most of New Mexico had been gained by the United States in their annexation of the Republic of Texas). The final portion of the Southwestern United States came about through the acquisition of the southernmost parts of Arizona and New Mexico through
15732-801: The Western Interior Seaway including the landbridge between the Mowry retreat and the Graneros advance: Kansas Kansas ( / ˈ k æ n z ə s / KAN -zəss ) is a state in the Midwestern region of the United States . It borders Nebraska to the north; Missouri to the east; Oklahoma to the south; and Colorado to the west. Kansas is named after the Kansas River , in turn named after
15903-644: The all-time highest temperature recorded in Kansas is (121 °F or 49.4 °C) on July 24, 1936, near Alton in Osborne County , and the all-time low is −40 °F (−40 °C) on February 13, 1905, near Lebanon in Smith County . Alton and Lebanon are approximately 50 miles (80 km) apart. Kansas's record high of 121 °F (49.4 °C) ties with North Dakota for the fifth-highest record high in an American state, behind California (134 °F or 56.7 °C), Arizona (128 °F or 53.3 °C), Nevada (125 °F or 51.7 °C), and New Mexico (122 °F or 50 °C). Known as rural flight ,
16074-678: The ancestral Puebloans. The modern-day Zuni established a culture along the Zuni River in far-eastern Arizona and western New Mexico. Both major tribes of the O'odham tribe settled in the southern and central Arizona, in the lands once controlled by their ancestors, the Hohokam. The first European intrusion into the region came from the south. In 1539, a Jesuit Franciscan named Marcos de Niza led an expedition from Mexico City which passed through eastern Arizona. The following year Francisco Vázquez de Coronado , based on reports from survivors of
16245-401: The ancient preserved soils show that an extensive flood plain forest was present. This Cretaceous seaway experienced a number of geological sequences (rise and fall cycles of sea level relative to land elevation), which, during particular lowstands, temporarily reestablished a land connection between the east and west continent at the ancestral Transcontinental Arch . Each sequence represents
16416-632: The area, namely the Animas , San Andres , and Doña Ana Mountains in New Mexico; and the Franklin , Hueco , and Davis Mountains in Texas. It also reaches up into the foothills of the higher ranges such as the Black Range and Oscura Mountains in New Mexico. High above the desert, these forest-covered and sometimes snow-capped mountains form sky islands , with radically different flora and fauna than
16587-589: The area, while the plateau (which is largely made up of high desert) is the main feature north of the Mogollon Rim . The two major rivers of the region are the Colorado River , running in the northern and western areas, and the Rio Grande , running in the east, north to south. Formed approximately 8000 years ago, the Chihuahuan Desert is a relatively dry desert, although it is slightly wetter than
16758-489: The area. The Chihuahuan Desert is considered the "most biologically diverse desert in the Western Hemisphere and one of the most diverse in the world," and includes more species of cacti than any other desert in the world. The most prolific plants in this region are agave , yucca and creosote bushes , in addition to the ubiquitous presence of various cacti species. When people think of the desert southwest,
16929-506: The arrival of Europeans, the Southwestern United States was inhabited by a very large population of American Indian tribes. The area once occupied by the ancestral Puebloans became inhabited by several American Indian tribes, the most populous of which were the Navajo , Ute , Southern Paiute , and Hopi. The Navajo, along with the Hopi, were the earliest of the modern Indian tribes to develop in
17100-472: The campus, Aggieville dates back to 1889 and is the state's oldest shopping district of its kind. In south-central Kansas, the Wichita metropolitan area is home to more than 600,000 people. Wichita is the largest city in the state in terms of both land area and population. 'The Air Capital' is a major manufacturing center for the aircraft industry and the home of Wichita State University . Before Wichita
17271-480: The center of the seaway. As these locations were at the time of formation the earliest and deepest areas of the seaway, these groups can include older ages of rocks than are usually included elsewhere under the Dakota name. The names of the member formations of the Dakota Group vary between these regions as the geology there is studied further; but, the earliest unit included in Dakota Groups, excluded elsewhere,
17442-584: The command of Lt. Colonel John Robert Baylor forced the surrender of the small Union garrison stationed at Fort Fillmore , near Mesilla, New Mexico . On August 1, 1861, Baylor declared the creation of the Arizona Territory , and claimed it for the Confederacy, with Mesilla as its capital. The territory, which had been formed by the portion of the existing New Mexico Territory below the 34th parallel, became official on February 14, 1862. Nevada
17613-514: The corresponding Skull Creek and Kiowa formations. These first two sequences are not present at the type area along the Missouri River. The sediments broadly considered as Dakota then record the Mowry sequence with the Muddy, J, or Lower Dakota sandstones and the D or Upper Dakota sandstones forming at the discontinuities at the beginning and end of that cycle. In the east the limited marine shales of
17784-453: The day. Precipitation ranges from about 47 inches (1,200 mm) annually in the state's southeast corner to about 16 inches (410 mm) in the southwest. Snowfall ranges from around 5 inches (130 mm) in the fringes of the south, to 35 inches (890 mm) in the far northwest. Frost-free days range from more than 200 days in the south, to 130 days in the northwest. Thus, Kansas is the country's ninth or tenth sunniest state, depending on
17955-432: The distinctive red sandstone exposures along the Missouri River near Dakota City , Nebraska. But, with this name, they applied the term "group", which at that time had the meaning of formation rank , as presently used. Dakota Formation is the unit's primary name and rank in the Great Plains . Formation rank is also applied in western extents (e.g., northeast Utah) as the unit thins and exhibits formational characteristics,
18126-473: The eastern and southern part of the state. The state's western half has exposures of Cretaceous through Tertiary sediments, the latter derived from the erosion of the uplifted Rocky Mountains to the west. These are underlain by older Paleozoic and Mesozoic sediments which correlate well with the outcrops to the east. The state's northeastern corner was subjected to glaciation in the Pleistocene and
18297-428: The ecology of those environments. Sandstone with dinosaur tracks in the upper Dakota above the marine Skull Creek Shale near Denver demonstrates that the seaway occasionally retreated from the area. Dinosaur fossils are very rare in the Dakota Formation and most of them come from Kansas. Some of them are found in Colorado and Nebraska. The most popular site for public viewing of Cretaceous dinosaur fossils in Colorado
18468-535: The establishment of Alta Ski Area , Utah's skiing began to be developed. Due to the ski conditions in the state, during WWII, the 10th Mountain Division established Camp Hale in Colorado to train elite ski troops. While this article deals with the core definition for the American Southwest, there are many others. The various definitions can be broken down into four main categories: Historical/Archeological; Geological/Topographical; Ecological; and Cultural. In
18639-410: The fastest-growing in the country. Kansas has 627 incorporated cities . By state statute, cities are divided into three classes as determined by the population obtained "by any census of enumeration". A city of the third class has a population of less than 5,000, but cities reaching a population of more than 2,000 may be certified as a city of the second class. The second class is limited to cities with
18810-688: The first female gubernatorial candidate in the state when she ran as "Mrs. W.D. Mowry". She later stated that, "Someone had to be the pioneer. I firmly believe that some day a woman will sit in the governor's chair in Kansas." Kansas suffered severe and environmental damage in the 1930s due to the combined effects of the Great Depression and the Dust Bowl , and large numbers of people left southwestern Kansas in particular for better opportunities elsewhere. The outbreak of World War II spurred rapid growth in aircraft manufacturing near Wichita in
18981-756: The former route of the Santa Fe Trail . Among cities with at least one thousand residents, Mission Hills has the highest median income in the state. Several institutions of higher education are located in Northeast Kansas including Baker University (the oldest university in the state, founded in 1858 and affiliated with the United Methodist Church ) in Baldwin City, Benedictine College (sponsored by St. Benedict's Abbey and Mount St. Scholastica Monastery and formed from
19152-552: The heart of the Southwest, called the "Santa Fe Route." It ran from Chicago, down through Topeka, then further south to Albuquerque, before heading almost due west through northern Arizona to Los Angeles. The repeal of the Sherman Silver Purchase Act in 1893 led to the decline of the silver mining industry in the region. In 1901, the Santa Fe Railroad reached the South Rim of the Grand Canyon, opening
19323-621: The heat index in those three cities is usually lower than the actual air temperature. Although temperatures of 100 °F (38 °C) or higher are not as common in areas east of U.S. 81, higher humidity and the urban heat island effect lead most summer days to heat indices between 107 and 114 °F (42 and 46 °C) in Topeka , Lawrence , and the Kansas City metropolitan area . Also, combined with humidity between 85 and 95 percent, dangerous heat indices can be experienced at every hour of
19494-428: The historical region of Santa Fe de Nuevo México as well as parts of Alta California and Coahuila y Tejas , settlement was almost non-existent outside of Nuevo México's Pueblos and Spanish or Mexican municipalities . Much of the area had been a part of New Spain and Mexico until the United States acquired the area through the Treaty of Guadalupe Hidalgo in 1848 and the smaller Gadsden Purchase in 1854. While
19665-708: The lands of the central and western portions of northern Arizona. Their village of Oraibi , settled in approximately AD 1100, is, along with Acoma Sky City in New Mexico, one of the oldest continuously occupied settlements in the United States. The Mogollon area became occupied by the Apaches and the Zuni. The Apache migrated into the American Southwest from the northern areas of North America at some point between 1200 and 1500. They settled throughout New Mexico, eastern Arizona, northern Mexico, parts of western Texas, and southern Colorado. The Zuni count their direct ancestry through
19836-413: The landscape of the Sonoran Desert is what mostly comes to mind. The Sonoran Desert makes up the southwestern portion of the Southwest; most of the desert lies in Mexico, but its United States component lies on the southeastern border of California, and the western 2/3 of southern Arizona. Rainfall averages between 4 and 12 in (100 and 300 mm) per year, and the desert's most widely known inhabitant
20007-528: The last few decades have been marked by a migratory pattern out of the countryside into cities. Out of all the cities in these Midwestern states, 89% have fewer than 3,000 people, and hundreds of those have fewer than 1,000. In Kansas alone, there are more than 6,000 ghost towns and dwindling communities, according to one Kansas historian, Daniel C. Fitzgerald. At the same time, some of the communities in Johnson County (metropolitan Kansas City) are among
20178-407: The last of the 48 contiguous United States on February 14, 1912. The 1930s saw the beginning of the ski industry in the Southwest. Resorts were established in Colorado in areas such as Estes Park , Gunnison , and on Loveland Pass . New Mexico's oldest ski area is Sandia Peak Ski Area at the eastern edge of Albuquerque , which opened to skiers in 1936. At the end of the decade, in 1939, with
20349-564: The late Early Cretaceous ( Albian ). This deposition marked a reversal from over 100 million years of erosion (most of the Mesozoic ). This reversal was due to rising of the mouth of the rivers, called a rise in base level, as the Cretaceous Seaway formed. This rise lowered the gradient of the rivers causing them to deposit sediment inland because their velocity could no longer sustain high volumes of sediment. Measurements show that
20520-723: The location of the Southwestern and Northwestern United States . In the early years of the United States, newly colonized lands lying immediately west of the Appalachian Mountains were detached from North Carolina and given the name Southwest Territory . During the decades that followed, the region known as "the Southwestern United States" covered much of the Deep South east of the Mississippi River. However, as territories and eventual states to
20691-676: The major US cities in this desert, with other smaller cities being Las Cruces and Roswell in New Mexico and Willcox in Arizona. The elevation in the Chihuahuan varies from about 1,750 to 6,000 feet (500 to 1,800 meters), as there are several larger mountain ranges, such as the Organ Mountains , the Guadalupe Mountains , and the Chiracahua Mountains , plus many smaller mountain ranges contained in
20862-585: The marine shales are absent, and fossil pollen species correlate with those found in the unit on the Missouri River . In the San Juan Basin and other intermontane basins and plateaus of the Southwest , Dakota Sandstone is the formal name for the oldest Cretaceous sandstone as well as tongues of that terrestrial sandstone extending into the dark marine shales of the Mancos . However, Dakota Sandstone
21033-771: The merger of St. Benedict's College (1858) and Mount St. Scholastica College (1923)) in Atchison, MidAmerica Nazarene University in Olathe, Ottawa University in Ottawa and Overland Park, Kansas City Kansas Community College and KU Medical Center in Kansas City, and KU Edwards Campus in Overland Park. Less than an hour's drive to the west, Lawrence is home to the University of Kansas , the largest public university in
21204-485: The middle of the 15th century AD: the Basketmaker I , II , and III phases followed by the Pueblo I , II , III , and IV . As the Puebloans transitioned from a nomadic lifestyle to one based on both dry land and irrigated agriculture, their first domiciles were pithouses. The Mogollon culture developed later than the Puebloan, arising in the eastern area of the region at around 300 BC. Their range would eventually extend deep into what would become Mexico, and dominate
21375-413: The name Dakota in spite of many efforts to apply localized names. Historically, Lower Cretaceous strata in the Rocky Mountain region have been called the Dakota Formation based on assumed correlation with the type section of the Dakota of the Great Plains. Witzke and Ludvigson have argued that use of the name "Dakota" must reflect actual, not presumed correlation based on stratigraphy and composition of
21546-409: The plains to the east, the same units are named Kiowa Shale and Cheyenne Sandstone , which are considered separate from the Dakota Formation as defined in Kansas and, moreover, do not appear at the type location in Nebraska. However, subsequent sequence stratigraphic and palynostratigraphic research has demonstrated that the Dakota Formation at the type location includes sand and mudstones covering
21717-580: The range of the usage of the Dakota name, the unit is primarily known for its massive beds of sandstone, which commonly shows shades of red, but also gray, yellow, or white. The sand was carried and deposited by rivers or accumulated in dunes or shoreline strands, and later cemented by red iron oxide or white calcite , depending on the local groundwater conditions that followed the sedimentation. The degree of cementation can range from softly crumbling to resistant to hammering. The sandstone beds can have local conglomerations of gravel. The composition of
21888-437: The region's boundaries are not officially defined, there have been attempts to do so. One such definition is from the Mojave Desert in California in the west (117° west longitude) to Carlsbad, New Mexico , in the east (104° west longitude); another says that it extends from the Mexico–United States border in the south to the southern areas of Colorado, Utah, and Nevada in the north (39° north latitude). In another definition,
22059-421: The revolt was unsuccessful. In fact, it had the exact opposite effect, for the result of the rebellion was the establishment of the presidio at Tubac , the first permanent European settlement in Arizona. In 1768, the Spanish created the Provincia de las Californias , which included California and the Southwest US. Over approximately the next 50 years, the Spanish continued to explore the Southwest, and in 1776
22230-421: The rivers flowed westward and southwestward towards the encroaching sea from source areas near the present-day Great Lakes . The point of deposition slowly moved eastward as the seaway rose. This change is seen by a gradual shift in the composition of sandstones from having a lot of Paleozoic-age rock detritus in Kansas to sandstones having all Precambrian crystalline rock debris in Iowa. This shift means that
22401-427: The rivers had completely eroded away the Paleozoic rocks in the river source area by the time the Seaway rose high enough for the rivers to deposit sediments in Iowa. The very top of the Dakota Formation was deposited along the coast as indicated by some fossil marine invertebrates . Fossil plants, coal deposits and kaolinite clays show that the climate was warm and wet during deposition of the Dakota Formation. Some of
22572-480: The same ages and sequences as the "marine shale facies of the Graneros" and "early Late Albian Kiowa-Skull Creek". In certain places, the classification is undivided; for example, in far southwest Utah , the strata is designated the Dakota Conglomerate without further division. When nearer the surface (within a couple thousand feet/hundreds of meters), the sandstone beds of the Dakota Formation form various Dakota Aquifers , important water sources in some areas of
22743-400: The same strata. Individual formations in the western Dakota Group have local names. In Wyoming, the term Cloverly Formation has been expanded by some authors to include sediments formerly placed within the Dakota Formation. Along the Colorado Front Range, the lower, terrestrial beds, or facies, of the Dakota Group are sometimes called the Lytle Formation, and near-shore marine facies are called
22914-513: The same time, the Chisholm Trail was opened and the Wild West era commenced in Kansas. Storied lawman Wild Bill Hickok was a deputy marshal at Fort Riley and a marshal at Hays and Abilene . Dodge City was home to both Bat Masterson and Wyatt Earp , who worked as lawmen in the town. The Dalton Gang robbed trains and banks throughout Kansas and the Southwest and maintained a hideout in Meade . In one year alone , eight million head of cattle from Texas boarded trains in Dodge City bound for
23085-405: The sand and gravel varies depending on the sources of the rivers that made each deposit. The amount of sandstone, averaging 25-50%, can very greatly over short distances between extremes of 5% to 80%. The general remainder of the unit, however, generally in complementary 80% to 5% proportions, is layered mudstone and clay deposited on floodplains, swamps, and estuaries. Similar to the sand,
23256-452: The seaway continued to deepen and widen, this eastern shoreline moved progressively eastward; however, accumulation of abundant sediment delivered by massive rivers limited shoreline advancement past the type location throughout the Cenomanian until overtopped by the Greenhorn Seaway in the early Turonian . Meanwhile, on the western side of the seaway, sediments were carried eastwards and northeastwards by rivers from mountains located along what
23427-409: The sedimentary rock. To the west of the Rocky Mountains, such as on the Colorado Plateau, this sequence of Upper Cretaceous, predominately sandstone, sedimentary rocks was recommended to be known as the Dakota Group, to dispel any suggestion of direct facies correlation. However, few authors of papers on the Dakota west of the Rocky Mountains, especially on the Colorado Plateau, recognize the Dakota as
23598-510: The sites of present-day Denver , Colorado Springs , and Pueblo . The first non-military settlement of Euro-Americans in Kansas Territory consisted of abolitionists from Massachusetts and other Free-Staters who founded the town of Lawrence and attempted to stop the spread of slavery from neighboring Missouri. Missouri and Arkansas continually sent settlers into Kansas Territory along its eastern border to sway votes in favor of slavery prior to Kansas statehood elections. Directly presaging
23769-402: The so-called Battle of Kansas , and the aerospace sector remains a significant portion of the Kansan economy to this day. Kansas is bordered by Nebraska to the north; Missouri to the east; Oklahoma to the south; and Colorado to the west. The state is divided into 105 counties with 628 cities , with its largest county by area being Butler County . Kansas is located equidistant from
23940-405: The soil-forming mud was modified by groundwater conditions to accumulate iron oxide or calcite. Coloration can be dark to light red, grey, yellow, and white. Iron oxide accumulation can approach the hardness and luster of hematite . In evidence of the general low-lying nature of the Dakota's lush, hot-house Earth environment, lignite and coal have formed in various areas. Marine shale is also
24111-402: The sought-after Southwestern architectural styles in the region inspired by blending Pueblo and Territorial styles, with Mediterranean Revival , Spanish Colonial architecture , Mission Revival architecture , Pueblo Deco , and Ranch-style houses in the form of the amalgamated Pueblo Revival and Territorial Revival architectures. This is due to the region's caballero heritage of
24282-750: The source. Western Kansas is as sunny as parts of California and Arizona . Kansas is prone to severe weather, especially in the spring and the early-summer. Despite the frequent sunshine throughout much of the state, due to its location at a climatic boundary prone to intrusions of multiple air masses, the state is vulnerable to strong and severe thunderstorms. Some of these storms become supercell thunderstorms; these can produce some tornadoes , occasionally those of EF3 strength or higher. Kansas averages more than 50 tornadoes annually. Severe thunderstorms sometimes drop some very large hail over Kansas as well. Furthermore, these storms can even bring in flash flooding and damaging straight line winds. According to NOAA,
24453-400: The south the 37th parallel . In 1862 Nevada's eastern border shifted to the 38th meridian west from Washington , and finally to its current position at the 37th meridian west from Washington in 1866. The boundary modification in 1866 also included adding the southern triangular tip of the present-day state, taken from the Arizona Territory. From July 24–27, 1861 a Confederate force under
24624-402: The southeastern portion of the Southwest. Their settlements would evolve over time from pit-dwellings through pueblos and finally also incorporating cliff-dwellings. The Hohokam were the last of these ancestral cultures to develop, somewhere around AD 1, but they would grow to be the most populous of the three by AD 1300, despite being the smallest of the three in terms of area, covering most of
24795-437: The southernmost sections of Oregon, Idaho, and Wyoming, as well as parts of southwest Nebraska, western Kansas, Oklahoma, and Texas. By 1977, the Society's definition had narrowed to only the four states of Utah, Arizona, Colorado, and New Mexico; and by 1982 the portion of the Southwest in the United States, as defined by the Society, had shrunk to Arizona and New Mexico, with the southernmost strip of Utah and Colorado, as well as
24966-403: The southwest portion. Beginning in approximately AD 600, the Hohokam began to develop an extensive series of irrigation canals; of the three major cultures in the Southwest, only the Ancestral Puebloans of the Chaco culture and the Hohokam developed irrigation as a means of watering their agriculture. Not long after the Hohokam reached the height of their culture, all three major cultures in
