The Tonto Trail is a hiking trail on the South Rim of the Grand Canyon in Grand Canyon National Park , located in the U.S. state of Arizona .
155-737: The Tonto Trail does not terminate at either rim of the Grand Canyon, but begins along the south bank of the Colorado River at Garnet Canyon (western end) and ends at Red Canyon (eastern end), also at the Colorado River. Through most of its 95-mile length, the trail runs along the Tonto Platform , the bench in the Grand Canyon that separates the inner gorge from the upper canyon. 95 miles (152.9 km): Garnet Canyon to Red Canyon Approximate mileages between key points on
310-603: A considerable number of words from Arabic , as well as a minor influence from the Germanic Gothic language through the period of Visigoth rule in Iberia. In addition, many more words were borrowed from Latin through the influence of written language and the liturgical language of the Church. The loanwords were taken from both Classical Latin and Renaissance Latin , the form of Latin in use at that time. According to
465-522: A dramatic change in the pronunciation of its sibilant consonants , known in Spanish as the reajuste de las sibilantes , which resulted in the distinctive velar [x] pronunciation of the letter ⟨j⟩ and—in a large part of Spain—the characteristic interdental [θ] ("th-sound") for the letter ⟨z⟩ (and for ⟨c⟩ before ⟨e⟩ or ⟨i⟩ ). See History of Spanish (Modern development of
620-464: A few decades before collapsing or being washed away. Failure of the lava dams caused by erosion, leaks and cavitation caused catastrophic floods, which may have been some of the largest ever to occur in North America, rivaling the late- Pleistocene Missoula Floods of the northwestern United States. Mapping of flood deposits indicate that crests as high as 700 feet (210 m) passed through
775-580: A few notable exceptions, such as the Blackrocks reach where the river is nearly 100 feet (30 m) deep. In a few areas, such as the marshy Kawuneeche Valley near the headwaters and the Grand Valley, it exhibits braided characteristics. From Grand Junction, the Colorado turns northwest before cutting southwest across the eponymous Colorado Plateau , a vast area of high desert centered at
930-482: A first language by Spaniards and educated Filipinos ( Ilustrados ). Despite a public education system set up by the colonial government, by the end of Spanish rule in 1898, only about 10% of the population had knowledge of Spanish, mostly those of Spanish descent or elite standing. Spanish continued to be official and used in Philippine literature and press during the early years of American administration after
1085-577: A large system of irrigation canals making use of the Salt River . Both civilizations supported large populations at their height, with 6,000–15,000 in Chaco Canyon and as many as 30,000–200,000 Hohokam. Puebloan and Hohokam settlements were abruptly abandoned in the 1400s CE, due both to over-exploitation of natural resources such as timber, and severe drought that made it impossible to maintain irrigation systems. Many Puebloans migrated east to
1240-478: A long history in the territory of the current-day United States dating back to the 16th century. In the wake of the 1848 Guadalupe Hidalgo Treaty , hundreds of thousands of Spanish speakers became a minoritized community in the United States. The 20th century saw further massive growth of Spanish speakers in areas where they had been hitherto scarce. According to the 2020 census, over 60 million people of

The three letter code indicates the park's use area designation (listed from east to west): Use permits are available on a first-come, first-served basis from the park's Backcountry Information Center. Requests are taken beginning on
1550-697: A military advantage over Goshutes and Southern Paiutes that were slower to adopt horses. The Navajo also adopted a culture of livestock herding as they acquired sheep and goats from the Spanish. Juan Bautista de Anza in 1774 was the first Spaniard to reach Yuma Crossing, where he established friendly relations with the Quechan people and opened the Anza trail between Arizona and the California coast. The Spanish soon founded Mission Puerto de Purisima Concepcion and Mission San Pedro y San Pablo de Bicuner along
1705-694: A mountain-building episode known as the Laramide orogeny . The Colorado River first formed as a west-flowing stream draining the southwestern portion of the range, and the uplift also diverted the Green River, once a tributary of the Mississippi River , west towards the Colorado. About 30 to 20 million years ago, volcanic activity related to the orogeny led to the Mid-Tertiary ignimbrite flare-up , which created smaller formations such as

Today, Spanish is present in the partially-recognized Sahrawi Arab Democratic Republic as its secondary official language, and in the Sahrawi refugee camps in Tindouf ( Algeria ), where the Spanish language is still taught as
2015-481: A route for a proposed railroad through the canyon, which was never built. We are now ready to start on our way down the Great Unknown. Our boats, tied to a common stake, are chafing each other, as they are tossed by the fretful river. They ride high and buoyant, for their loads are lighter than we could desire. We have but a month's rations remaining… The lighting of the boats has this advantage: they will ride
2170-617: A second language features characteristics involving the variability of the vowel system. While far from its heyday during the Spanish protectorate in Morocco , the Spanish language has some presence in northern Morocco , stemming for example from the availability of certain Spanish-language media. According to a 2012 survey by Morocco's Royal Institute for Strategic Studies (IRES), penetration of Spanish in Morocco reaches 4.6% of

Spanish was an official language of the Philippines from the beginning of Spanish administration in 1565 to a constitutional change in 1973. During Spanish colonization , it was the language of government, trade, and education, and was spoken as
2480-475: A series of international and US interstate treaties known as the " Law of the River ". The US federal government constructed most of the major dams and aqueducts between 1910 and 1970; the largest, Hoover Dam , was completed in 1935. Numerous water projects have also involved state and local governments. With all of their waters fully allocated, both the Colorado and the neighboring Rio Grande are now considered among
2635-490: A short run south, the river turns west below Grand Lake , the largest natural lake in the state. For the first 250 miles (400 km) of its course, the Colorado carves its way through the mountainous Western Slope , a sparsely populated region defined by the portion of the state west of the Continental Divide . As it flows southwest, it gains strength from many small tributaries, as well as larger ones including
2790-474: A significant distance from the river. The Puebloan people built many multi-story pueblos or "great houses", and developed complex distribution systems to supply drinking and irrigation water in Chaco Canyon in northwestern New Mexico and Mesa Verde in southwest Colorado. The Hohokam , present in the modern Phoenix area since about 0 CE, experienced prolific growth around 600-700 CE as they constructed

An additional 75 million speak Spanish as a second or foreign language , making it the fourth most spoken language in the world overall after English, Mandarin Chinese, and Hindi with a total number of 538 million speakers. Spanish is also
3720-761: Is heavily influenced by Venezuelan Spanish. In addition to sharing most of its borders with Spanish-speaking countries, the creation of Mercosur in the early 1990s induced a favorable situation for the promotion of Spanish language teaching in Brazil . In 2005, the National Congress of Brazil approved a bill, signed into law by the President , making it mandatory for schools to offer Spanish as an alternative foreign language course in both public and private secondary schools in Brazil. In September 2016 this law

For over a decade, U.S. Representative Edward T. Taylor of Colorado had petitioned the Congressional Committee on Interstate and Foreign Commerce to rename the Grand River as the Colorado River. Representatives from Wyoming, Utah, and
4340-732: Is related to Castile ( Castilla or archaically Castiella ), the kingdom where the language was originally spoken. The name Castile , in turn, is usually assumed to be derived from castillo ('castle'). In the Middle Ages , the language spoken in Castile was generically referred to as Romance and later also as Lengua vulgar . Later in the period, it gained geographical specification as Romance castellano ( romanz castellano , romanz de Castiella ), lenguaje de Castiella , and ultimately simply as castellano (noun). Different etymologies have been suggested for
4495-571: Is significantly more pronounced in the Lower Basin, where it has a strong impact on monsoonal rainfall. Runoff patterns across the Colorado River Basin reflect this; most of the perennial tributaries originate in the Upper Basin, while tributaries in the Lower Basin are either ephemeral (such as the Little Colorado River) or highly seasonal (such as the Gila and Salt rivers). As of 2010, approximately 13 million people lived within
4650-844: Is spoken by very small communities in Angola due to Cuban influence from the Cold War and in South Sudan among South Sudanese natives that relocated to Cuba during the Sudanese wars and returned for their country's independence.

By the early 1900s the name "Grand River" had been attached to the entire stream as far as Grand Lake, which was then considered its official source. Although the Grand River was renamed the Colorado in 1921, its name survives in numerous places such as Grand County and Grand Junction, Colorado. In 1848
5270-585: The Baja California – Sonora border. Since 1960, the stretch of the Colorado between here and the Gulf of California has been dry or a trickle formed by irrigation return flows. The Hardy River provides most of the flow into the Colorado River Delta , a vast alluvial floodplain covering about 3,000 square miles (7,800 km ) of northwestern Mexico. A large estuary is formed here before

Here, the climate becomes significantly drier than that in the Rocky Mountains, and the river becomes entrenched in progressively deeper gorges of bare rock, beginning with Ruby Canyon and then Westwater Canyon as it enters Utah , now once again heading southwest. Farther downstream it receives the Dolores River and defines the southern border of Arches National Park , before passing Moab and flowing through "The Portal", where it exits
6200-556: The Fremont culture period (0–1300 CE). The Ancient Puebloan culture, also known as Anasazi or Hisatsinom, were descended from the Desert Archaic culture and became established in the Four Corners region around 1000 CE. While there is much evidence of ancient habitation along the Colorado River, including stone dwellings, petroglyphs and pottery in places such as Glen Canyon, the first major agriculture-based societies arose
6355-799: The Grand Mesa ; the Weenuchiu lived along the San Juan River, and the Parianuche and Yamparika lived in the Yampa, White and Duchesne River valleys. The Ute ranged as far as the river’s headwaters; one Ute story recounts a battle with the Arapaho at Grand Lake, which they believe still hosts the spirits of the deceased. Starting in the 1500s, the Spanish began to explore and colonize western North America. Francisco de Ulloa may have been

Crustal extension in the Basin and Range Province began about 20 million years ago and the modern Sierra Nevada began forming about 10 million years ago, eventually diverting the Colorado southwards towards the Gulf. As the Colorado Plateau continued to rise between 5 and 2.5 million years ago, the river maintained its ancestral course (as an antecedent stream ) and began to cut
6975-435: The Navajo settled in the Colorado Basin after the 1000s. In the 1500s, Spanish explorers began mapping and claiming the watershed, which became part of Mexico upon winning its independence from Spain in 1821. Even after most of the watershed became US territory in 1846, much of the river's course remained unknown. Several expeditions charted the Colorado in the mid-19th century—one of which, led by John Wesley Powell ,

Small numbers of Paleo-Indians of the Clovis and Folsom cultures inhabited the Colorado Plateau as early as 10,000 BCE, with populations beginning to increase in the Desert Archaic period (6000 BCE–0 CE). While most early inhabitants were hunter-gatherers, evidence of agriculture, masonry dwellings and petroglyphs begins with
11780-540: The Grand Canyon. Antecedence played a major part in shaping other peculiar geographic features in the watershed, including the Dolores River's bisection of Paradox Valley in Colorado and the Green River's cut through the Uinta Mountains in Utah. Sediments carried from the plateau by the Colorado River created a vast delta made of more than 10,000 cubic miles (42,000 km ) of material that walled off
11935-412: The Grand Canyon. At least 13 lava dams were formed, the largest of which was more than 2,300 feet (700 m) high, backing the river up for nearly 500 miles (800 km) to present-day Moab, Utah. The lack of associated sediment deposits along this stretch of the Colorado River, which would have accumulated in the impounded lakes over time, suggests that most of these dams did not survive for more than
12090-705: The Iberian Peninsula. These languages included Proto-Basque , Iberian , Lusitanian , Celtiberian and Gallaecian . The first documents to show traces of what is today regarded as the precursor of modern Spanish are from the 9th century. Throughout the Middle Ages and into the modern era , the most important influences on the Spanish lexicon came from neighboring Romance languages — Mozarabic ( Andalusi Romance ), Navarro-Aragonese , Leonese , Catalan/Valencian , Portuguese , Galician , Occitan , and later, French and Italian . Spanish also borrowed
12245-734: The Lost Orphan Uranium Mine (defunct) below Powell Point. The park's Backcountry Information Center has current water conditions for all water sources along the Tonto Trail. Camping is allowed along the Tonto Trail by permit only, issued by the Grand Canyon National Park Backcountry Information Center. Use of these areas overnight are regulated by the National Park Service , and they call for
12400-516: The Lower Basin from August through October, contributing much of the flow in tributaries below Lees Ferry and often causing flash flooding . Since the initial closure of Hoover Dam in 1934, lower Colorado River flows have been greatly moderated, with monthly means below the dam ranging from 16,400 cu ft/s (460 m /s) in May to 11,200 cu ft/s (320 m /s) in October. Upstream of
12555-657: The Moab Valley between a pair of 1,000-foot (300 m) sandstone cliffs. In Utah, the Colorado flows primarily through the " slickrock " country, which is characterized by its narrow canyons and unique "folds" created by the tilting of sedimentary rock layers along faults. This is one of the most inaccessible regions of the continental United States. Below the confluence with the Green River , its largest tributary, in Canyonlands National Park ,

The Gramática de la lengua castellana , written in Salamanca in 1492 by Elio Antonio de Nebrija , was the first grammar written for a modern European language. According to a popular anecdote, when Nebrija presented it to Queen Isabella I , she asked him what was the use of such a work, and he answered that language is the instrument of empire. In his introduction to
12865-630: The Rio Grande Valley, while others persisted in smaller settlements on the Colorado Plateau. Puebloan descendants include the Hopi , Zuni , Laguna and Acoma peoples of modern Arizona and New Mexico. O'odham peoples, including the Akimel O'odham (Pima) and Maricopa who continue to live in southern Arizona, are believed to be descended from the Hohokam. The lower Colorado River valley
13020-644: The Rockies to less than 4 inches (100 mm) in dry desert valleys. The Upper Basin generally receives snow and rain during the winter and early spring, while precipitation in the Lower Basin falls mainly during intense but infrequent summer thunderstorms brought on by the North American Monsoon . Precipitation is influenced by the El Niño-Southern Oscillation (ENSO) with El Niño being associated with wetter conditions and La Niña with drier conditions. The effect of ENSO
13175-535: The Rockies. Water diversions have effectively removed some tributaries entirely, including the Gila River, once the Colorado's largest tributary below Lees Ferry. Most Colorado River water is diverted in the United States, with only about 2.8 million acre-feet (3.5 km ) per year reaching Mexico since 1950. At Morelos Dam, the remaining flow is diverted to irrigate the Mexicali Valley, leaving
13330-533: The South Kaibab Trail or west of the Hermit Trail are more likely to find solitude and isolation in addition to other hazards related to desert hiking. 36°04′35″N 112°06′24″W / 36.0764°N 112.10655°W / 36.0764; -112.10655 Colorado River The Colorado River ( Spanish : Río Colorado ) is one of the principal rivers (along with the Rio Grande ) in
13485-535: The Spanish called the Colorado were in fact connected. William H. Ashley made an unsuccessful attempt to navigate from the Green River to the Colorado's mouth in 1825. In 1826, Jedediah Smith arrived at the lower Colorado River, referring to it as the Seedskeedee, and proceeded upstream, exploring as far as Black Canyon. During the 1830s, various fur trappers from Wyoming made it as far downstream as Cataract Canyon and Glen Canyon, but none were able to navigate
13640-597: The Spanish-speaking world, Spanish is called not only español but also castellano (Castilian), the language from the Kingdom of Castile , contrasting it with other languages spoken in Spain such as Galician , Basque , Asturian , Catalan/Valencian , Aragonese , Occitan and other minor languages. The Spanish Constitution of 1978 uses the term castellano to define the official language of

13950-495: The U.S. Army established Fort Yuma , creating the first permanent U.S. settlement along the river. This served as a military garrison and supply point for settlers headed to California along the Southern Emigrant Trail . Due to the arduous task of ferrying supplies overland, the schooner Invincible attempted to bring supplies up the river but was thwarted by the delta’s strong tides. Steamboats were brought to
14105-502: The U.S. population were of Hispanic or Hispanic American by origin. In turn, 41.8 million people in the United States aged five or older speak Spanish at home, or about 13% of the population. Spanish predominates in the unincorporated territory of Puerto Rico , where it is also an official language along with English. Spanish is by far the most common second language in the country, with over 50 million total speakers if non-native or second-language speakers are included. While English
14260-625: The Virgin River, enabled shipping of their produce by wagon to gold mining districts further south. Although the Mormons abandoned St. Thomas in 1871, a salt-mining industry persisted here, and steamboats operated up to nearby Rioville into the 1880s. In 1879 a group of Mormon settlers made their way to southeastern Utah, blasting the precarious Hole in the Rock Trail to cross the Colorado River at Glen Canyon, subsequently establishing
14415-517: The administration of Ferdinand Marcos two months later. It remained an official language until the ratification of the present constitution in 1987, in which it was re-designated as a voluntary and optional auxiliary language. Additionally, the constitution, in its Article XIV, stipulates that the Government shall provide the people of the Philippines with a Spanish-language translation of
14570-582: The beginning of the Grand Canyon , passing under the Navajo Bridges on a now southward course. Below the confluence with the Little Colorado River , the river swings west into Granite Gorge, the most dramatic portion of the Grand Canyon, where the river cuts up to one mile (1.6 km) into the Colorado Plateau, exposing some of the oldest visible rocks on Earth, dating as long ago as 2 billion years. The 277 miles (446 km) of
14725-468: The central portion. The Colorado Plateau is home to most of the major canyon systems formed by the Colorado River and its tributaries, particularly those of the Green and San Juan rivers. About 23 percent of the basin is forest, with the largest area in the Rocky Mountains; other significant forested areas include the Kaibab , Aquarius , and Markagunt plateaus in southern Utah and northern Arizona, and
14880-432: The channel, we know not; what walls rise over the river, we know not; Ah, well! we may conjecture many things. The men talk as cheerfully as ever; jests are bandied about freely this morning; but to me the cheer is somber and the jests are ghastly. In 1858, gold was discovered on the Gila River east of Yuma, then along the Colorado River at El Dorado Canyon, Nevada and La Paz, Arizona . As prospectors and settlers entered
15035-751: The classic hispanus or hispanicus took the suffix -one from Vulgar Latin , as happened with other words such as bretón (Breton) or sajón (Saxon). Like the other Romance languages , the Spanish language evolved from Vulgar Latin , which was brought to the Iberian Peninsula by the Romans during the Second Punic War , beginning in 210 BC. Several pre-Roman languages (also called Paleohispanic languages )—some distantly related to Latin as Indo-European languages , and some that are not related at all—were previously spoken in
15190-589: The community of Bluff . Due to the dry climate, these settlements depended heavily on irrigation. In central Arizona, settlers uncovered and re-established canals previously used by the Hohokam. Following tensions between Mormon settlers and the U.S. government in the Utah War , a local militia including John D. Lee perpetrated the 1857 Mountain Meadows Massacre , in which 120 non-Mormon settlers were killed. Fearing retribution, Lee moved in 1870 to
15345-500: The consonant written b (a bilabial with plosive and fricative allophones). In modern Spanish, there is no difference between the pronunciation of orthographic b and v . Typical of Spanish (as also of neighboring Gascon extending as far north as the Gironde estuary , and found in a small area of Calabria ), attributed by some scholars to a Basque substratum was the mutation of Latin initial f into h- whenever it
15500-404: The country's constitution. In recent years changing attitudes among non-Spanish speaking Filipinos have helped spur a revival of the language, and starting in 2009 Spanish was reintroduced as part of the basic education curriculum in a number of public high schools, becoming the largest foreign language program offered by the public school system, with over 7,000 students studying the language in
15655-521: The course of a week, or even a day." The LCRV is one of the most densely populated areas along the river, and there are numerous towns including Bullhead City, Arizona , Needles, California , and Lake Havasu City, Arizona . Here, several large diversions draw from the river, providing water for both local uses and distant regions including the Salt River Valley of Arizona and metropolitan Southern California . The last major U.S. diversion
15810-540: The dam is an integral component for management of the Colorado River, controlling floods and storing water for farms and cities in the lower Colorado River basin. Below the dam the river passes under the Mike O'Callaghan–Pat Tillman Memorial Bridge —which at nearly 900 feet (270 m) above the water is the highest concrete arch bridge in the Western Hemisphere —and then turns due south towards Mexico, defining
15965-582: The easiest to follow. Less traveled sections are subject to overgrowth by canyon flora early in the spring season, and may require route finding skills to traverse. All water sources along this trail must be treated, filtered, or boiled before drinking, with the exception of water available at the junction with the Bright Angel Trail (at Indian Garden). Hermit Creek, Monument Creek, and Garden Creek flow year round and can be consumed after purification. Water from Horn Creek should be avoided except in emergency circumstances due to radioactive contamination from
16120-658: The east side of the divide drain into the Mississippi River and Rio Grande , while nearby areas north of the Wind River Range drain into the Columbia River . The western boundary of the Colorado River Basin is formed by various ranges and plateaus that border the Great Basin , including the Uinta Mountains and Wasatch Range . Major Great Basin watersheds bordering the Colorado River Basin are

Harding signed House Joint Resolution 32 - “To change the name of the Grand River in Colorado and Utah to the Colorado River.” Spanish language This is an accepted version of this page Spanish ( español ) or Castilian ( castellano ) is a Romance language of the Indo-European language family that evolved from
16430-468: The ferry obsolete. The Denver and Salt Lake Railway (D&SL), incorporated in 1902, sought to provide a more direct connection between Denver and Salt Lake City than either the transcontinental railroad through Wyoming or the D&RGW’s route via Black Canyon and Durango. The D&SL completed a rail line into the upper headwaters of the Colorado River and blasted the Moffat Tunnel under
16585-468: The first European to see the river, when in 1536 he sailed to the head of the Gulf of California. In 1540 García López de Cárdenas became the first European to see the Grand Canyon, during Coronado 's expedition to find the Seven Cities of Gold ("Cibola"). Cárdenas was apparently unimpressed with the canyon, greatly underestimating its size, and left in disappointment with no gold to be found. In
16740-408: The first known inhabitants of this part of the Rocky Mountains, and made use of an extensive network of trails crisscrossing the mountains to move between summer and winter camps. The Ute were divided into numerous bands with separate territories but shared a common language and customs. The Uncompahgre or Tabeguache lived around the confluence of the upper Colorado and Gunnison Rivers, an area including
16895-452: The first part of non-natives to travel the length of the Grand Canyon, and the first to successfully travel by boat from the upper Green River to the lower Colorado. Powell led a second expedition in 1871, with financial backing from the U.S. government, and continued to conduct geographical and botanical surveys across the region until the 1890s. Another Grand Canyon river expedition was led in 1889-1890 by Robert Brewster Stanton to survey
17050-683: The following table: Spanish is marked by palatalization of the Latin double consonants ( geminates ) nn and ll (thus Latin annum > Spanish año , and Latin anellum > Spanish anillo ). The consonant written u or v in Latin and pronounced [w] in Classical Latin had probably " fortified " to a bilabial fricative /β/ in Vulgar Latin. In early Spanish (but not in Catalan or Portuguese) it merged with
17205-466: The former British colony of Belize (known until 1973 as British Honduras ) where English is the sole official language, according to the 2022 census, 54% of the total population are able to speak the language. Due to its proximity to Spanish-speaking countries and small existing native Spanish speaking minority, Trinidad and Tobago has implemented Spanish language teaching into its education system. The Trinidadian and Tobagonian government launched
17360-582: The founding of Breckenridge, Colorado . Up until the 1860s, southwestern Colorado had remained relatively untouched by U.S. westward expansion, as the Americans had recognized Ute sovereignty by treaty. Following the 1861 carving out of Colorado Territory and further mineral strikes including Ouray and Telluride , Ute leaders were coerced into signing the 1873 Brunot Agreement , in which they lost rights to most of their land. A flood of mineral prospecting and settlement ensued in western Colorado. By 1881,
17515-485: The full length of the river. In 1843 John C. Frémont explored the Great Basin and conclusively determined no Buenaventura River flowed west to California; thus, the direction of river flow must be southwest. By the early 19th century, the stretch of the Colorado above the confluence of the Green River at Cataract Canyon , Utah, became known to fur trappers as the "Grand River", though the exact origin of this name
17670-604: The grammar, dated 18 August 1492, Nebrija wrote that "... language was always the companion of empire." From the 16th century onwards, the language was taken to the Spanish-discovered America and the Spanish East Indies via Spanish colonization of America . Miguel de Cervantes , author of Don Quixote , is such a well-known reference in the world that Spanish is often called la lengua de Cervantes ("the language of Cervantes"). In
17825-536: The intermittent Gila River —which carries runoff from western New Mexico and most of Arizona–before defining 24 miles (39 km) of the Mexico–United States border . At Morelos Dam , the entire remaining flow of the Colorado is diverted to irrigate the Mexicali Valley , among Mexico's most fertile agricultural lands. Below San Luis Río Colorado , the Colorado passes entirely into Mexico, defining
17980-513: The internet by number of users after English and Chinese and the second most used language by number of websites after English. Spanish is used as an official language by many international organizations , including the United Nations , European Union , Organization of American States , Union of South American Nations , Community of Latin American and Caribbean States , African Union , among others. In Spain and some other parts of
18135-753: The land area of the Colorado River Basin, but contributes 92 percent of the runoff. The entire eastern boundary of the Colorado River Basin runs along the North American Continental Divide and is defined largely by the Rocky Mountains and the Rio Grande Basin . The Wind River Range in Wyoming marks the northern extent of the basin, and is separated from the Colorado Rockies by the endorheic Great Divide Basin in southwestern Wyoming. Streams that are nearby
18290-549: The language's hegemony in an intensely centralising Spanish state were established from the 18th century onward. Other European territories in which it is also widely spoken include Gibraltar and Andorra . Spanish is also spoken by immigrant communities in other European countries, such as the United Kingdom , France , Italy , and Germany . Spanish is an official language of the European Union . Today,
18445-491: The lower 100 miles (160 km) of the river, which has rarely reached the sea since the 1960s. Native Americans have inhabited the Colorado River basin for at least 8,000 years. Starting around 1 CE, large agriculture-based societies were established, but a combination of drought and poor land use practices led to their collapse in the 1300s. Their descendants include tribes such as the Puebloans , while others including
18600-513: The lower Colorado River. However, Spanish attempts to control the crossing led to the 1781 Yuma revolt, in which over 100 soldiers and colonists were killed, and the settlements were abandoned. The Quechan blocked foreigners’ use of the crossing until the arrival of American mountain men and fur trappers in the 1820s. The name Rio Colorado first appears in 1701, on the map "Paso por Tierra a la California" published by missionary Eusebio Kino , who also determined during that time that Baja California
18755-565: The majority of Colorado River runoff. Tributaries between there and Imperial Dam near the US–Mexico border contribute a further 1.1 million acre-feet (1.4 km ), and the Gila– Salt River system historically accounted for another 1.7 million acre-feet (2.1 km ). While much of this water was lost to evaporation in the deserts of the Lower Basin, anywhere from 10 to 20 million acre-feet (12 to 25 km ) per year reached
18910-694: The majority of the Spanish speakers live in Hispanic America . Nationally, Spanish is the official language—either de facto or de jure —of Argentina , Bolivia (co-official with 36 indigenous languages), Chile , Colombia , Costa Rica , Cuba , Dominican Republic , Ecuador , El Salvador , Guatemala , Honduras , Mexico (co-official with 63 indigenous languages), Nicaragua , Panama , Paraguay (co-official with Guaraní ), Peru (co-official with Quechua , Aymara , and "the other indigenous languages"), Puerto Rico (co-official with English), Uruguay , and Venezuela . Spanish language has
19065-495: The massive Hoover and Glen Canyon Dams, inflows to Lake Powell still experience distinct spring highs and winter lows, though overall volumes have been reduced due to Upper Basin water diversions. Flow regimes in a few Upper Basin tributaries, such as the Yampa River , remain almost completely unaltered. By the 1950s, the Colorado delta was regularly drying up in fall and winter, though spring high flows often still made it to
19220-569: The most controlled and litigated river systems in the world. Since 2000, extended drought has conflicted with increasing demands for Colorado River water, and the level of human development and control of the river continues to generate controversy. The Colorado begins at La Poudre Pass in the Never Summer Mountains in Rocky Mountain National Park , 10,184 ft (3,104 m) above sea level. After
19375-688: The north and south, and enabled the expansion of trade to the Pima and Maricopa in the east and coastal California tribes in the west. The Navajo (Diné) began migrating into the Colorado River Basin around 1000-1500 CE, and eventually exercised influence over much of the Colorado Plateau. Originally hunter-gatherers, they acquired knowledge of farming from the Puebloans and adopted a more sedentary lifestyle over time, making extensive use of irrigation in their settlements. The Navajo gradually displaced Hopi settlements as they expanded into northern Arizona after
19530-762: The north rim via the North Kaibab Trail . At Garnet Canyon, the Tonto Trail officially ends, but a trail continues along the Colorado River to Elves Chasm. There is also a junction with the Royal Arch Route , which requires a short rappel to access the river trail. At Red Canyon, the eastern end of the Tonto Trail , the Escalante Route continues eastward, connecting to the Tanner Trail and Beamer Trail at Tanner Rapids. There
19685-524: The northernmost part of the gulf in approximately 1 million years. Cut off from the ocean, the portion of the gulf north of the delta eventually evaporated and formed the Salton Sink , which reached about 260 feet (79 m) below sea level. Since then the river has changed course into the Salton Sink at least three times, transforming it into Lake Cahuilla , which at maximum size flooded up
19840-790: The northwest of the African mainland. The Spanish spoken in the Canary Islands traces its origins back to the Castilian conquest in the 15th century , and, in addition to a resemblance to Western Andalusian speech patterns, it also features strong influence from the Spanish varieties spoken in the Americas, which in turn have also been influenced historically by Canarian Spanish. The Spanish spoken in North Africa by native bilingual speakers of Arabic or Berber who also speak Spanish as
19995-423: The ocean. After the initial closure of Glen Canyon Dam in 1963, these seasonal flows were almost completely eliminated, with the exception of a few very wet years, such as 1983–1987. In 1984, 16.5 million acre-feet (20.4 km ) of excess runoff reached the ocean. Flows have further declined due to evaporation from reservoirs and, particularly after 2000, reduced snowpack with warming winter temperatures in
20150-654: The other hand, currently uses the term español in its publications. However, from 1713 to 1923, it called the language castellano . The Diccionario panhispánico de dudas (a language guide published by the Royal Spanish Academy) states that, although the Royal Spanish Academy prefers to use the term español in its publications when referring to the Spanish language, both terms— español and castellano —are regarded as synonymous and equally valid. The term castellano
20305-481: The population. Many northern Moroccans have rudimentary knowledge of Spanish, with Spanish being particularly significant in areas adjacent to Ceuta and Melilla. Spanish also has a presence in the education system of the country (through either selected education centers implementing Spain's education system, primarily located in the North, or the availability of Spanish as foreign language subject in secondary education). In Western Sahara , formerly Spanish Sahara ,
20460-407: The railroad had reached Grand Junction, and a spur up the Colorado to Glenwood Springs was completed in 1887. In Arizona and Utah Territories , many early settlers were Mormons fleeing religious persecution in the Midwest. Mormons founded agricultural colonies at Fort Santa Clara in 1855 and St. Thomas , now flooded under Lake Mead, in 1865. Stone's Ferry , crossing the Colorado at the mouth of
20615-402: The region, they became involved in skirmishes with the Mohave, spurring U.S. Army expeditions that culminated in the 1859 Battle of the Colorado River which concluded the Mohave War . In the 1870s the Mohave were moved to the Fort Mohave and Colorado River reservations. Chemehuevi and later some Hopi and Navajo peoples were also moved to the Colorado River reservation, where they today form
20770-404: The remote Pahreah Crossing in Arizona, where he took over a ferry first established in 1864 by Jacob Hamblin . This, the only river crossing for hundreds of miles not hemmed in by vertical canyon walls, became known as Lee's Ferry . While Lee was tried and subsequently executed in 1877, the ferry remained a major transportation link until the Navajo Bridge was completed nearby in 1928, rendering
20925-454: The river that flow through the Grand Canyon are largely encompassed by Grand Canyon National Park and are known for their difficult whitewater, separated by pools that reach up to 110 feet (34 m) in depth. At the lower end of Grand Canyon, the Colorado widens into Lake Mead , the largest reservoir in the continental United States, formed by Hoover Dam on the border of Arizona and Nevada . Situated southeast of metropolitan Las Vegas ,
21080-401: The river's present course and the Grand Canyon were formed is uncertain. Before the Gulf of California was formed around 12 to 5 million years ago by faulting processes along the boundary of the North American and Pacific plates, the Colorado flowed west to an outlet on the Pacific Ocean—possibly Monterey Bay on the Central California coast, and may have played a role in the formation of
21235-528: The river's suitability as a navigation route, Ives remarked: "Ours has been the first, and will doubtless be the last, party of whites to visit this profitless locality. It seems intended by nature that the Colorado River, along the greater portion of its lonely and majestic way, shall be forever unvisited and undisturbed." The last part of the Colorado River to be surveyed was the Grand Canyon itself. In 1869, John Wesley Powell with nine men set out on an expedition from Green River Station, Wyoming . They were
21390-512: The river, starting in 1852 with the sidewheeler Uncle Sam , whose first voyage from the Gulf to Yuma took fifteen days. Exploration by steamboat soon advanced upriver. In 1857, George A. Johnson in the General Jesup was able to reach Pyramid Canyon , over 300 miles (480 km) north of Fort Yuma. He was followed by Lt. Joseph Christmas Ives who used a specially built shallow-draft steamboat, Explorer , to reach Black Canyon , where Hoover Dam stands today. Having set out to determine
21545-413: The same year Melchior Díaz explored the Colorado River's delta and named it Rio del Tizon ("fire brand river"), after seeing a practice used by the local people for warming themselves. By the late 1500s or early 1600s, the Utes had acquired horses from the Spanish, and their use for hunting, trade and warfare soon became widespread among Utes and Navajo in the Colorado River basin. This conferred them
21700-454: The seventh largest drainage basin in North America. About 238,600 square miles (618,000 km ), or 97 percent of the basin, is in the United States. The basin extends into western Colorado and New Mexico, southwestern Wyoming , eastern and southern Utah, southeastern Nevada and California, and most of Arizona. The areas drained within Baja California and Sonora in Mexico are very small and do not contribute significant runoff. Aside from
21855-431: The term español (Spanish). According to the Royal Spanish Academy, español derives from the Occitan word espaignol and that, in turn, derives from the Vulgar Latin * hispaniolus ('of Hispania'). Hispania was the Roman name for the entire Iberian Peninsula . There are other hypotheses apart from the one suggested by the Royal Spanish Academy. Spanish philologist Ramón Menéndez Pidal suggested that
22010-444: The theories of Ramón Menéndez Pidal , local sociolects of Vulgar Latin evolved into Spanish, in the north of Iberia, in an area centered in the city of Burgos , and this dialect was later brought to the city of Toledo , where the written standard of Spanish was first developed, in the 13th century. In this formative stage, Spanish developed a strongly differing variant from its close cousin, Leonese , and, according to some authors,
22165-465: The third most used language on the Internet , after English and Chinese. Spanish is the official language of Spain . Upon the emergence of the Castilian Crown as the dominant power in the Iberian Peninsula by the end of the Middle Ages, the Romance vernacular associated with this polity became increasingly used in instances of prestige and influence, and the distinction between "Castilian" and "Spanish" started to become blurred. Hard policies imposing
22320-440: The tidal bore—locally called El Burro —formed in the estuary about Montague Island in Baja California and propagated upstream. The Colorado is joined by over 25 significant tributaries, of which the Green River is the largest by both length and discharge. The Green River takes drainage from the Wind River Range of west-central Wyoming, from Utah's Uinta Mountains , and from the Rockies of northwestern Colorado. The Gila River
22475-423: The valley to present-day Indio, California . The lake took about 50 years to evaporate after the Colorado resumed flowing to the Gulf. The present-day Salton Sea can be considered the most recent incarnation of Lake Cahuilla, though on a much smaller scale. Between 1.8 million and 10,000 years ago, massive flows of basalt from the Uinkaret volcanic field in northern Arizona dammed the Colorado River within
22630-509: The waves better, and we shall have little to carry when we make a portage. We are three-quarters of a mile in the depths of the earth, and the great river shrinks into insignificance, as it dashes its angry waves against the walls and cliffs, that rise to the world above; they are but puny ripples, and we but pigmies, running up and down the sands, or lost among the boulders. We have an unknown distance yet to run; an unknown river yet to explore. What falls there are, we know not; what rocks beset
22785-533: The whole of Spain, in contrast to las demás lenguas españolas (lit. "the other Spanish languages "). Article III reads as follows: El castellano es la lengua española oficial del Estado. ... Las demás lenguas españolas serán también oficiales en las respectivas Comunidades Autónomas...

23095-484: Was a peninsula, not an island as previously believed. In the 1700s and early 1800s many Spanish and American explorers believed in the existence of a Buenaventura River that ran from the Rocky Mountains to the Pacific coast. In 1776, Silvestre Vélez de Escalante attached this name to the upper Green River, and a number of later maps showed this connecting to Lake Timpanogos (now Utah Lake ) and flowing west to California. The Dominguez–Escalante expedition first reached
23250-581: Was developed in the cities of Toledo , in the 13th to 16th centuries, and Madrid , from the 1570s. The development of the Spanish sound system from that of Vulgar Latin exhibits most of the changes that are typical of Western Romance languages , including lenition of intervocalic consonants (thus Latin vīta > Spanish vida ).

The written standard for this new language

The h- , still preserved in spelling, is now silent in most varieties of the language, although in some Andalusian and Caribbean dialects, it is still aspirated in some words.

Enshrined in the constitution as an official language (alongside French and Portuguese), Spanish features prominently in
24025-446: Was the first to run the rapids of the Grand Canyon. Large-scale settlement of the lower basin began in the mid- to late-1800s, with steamboats sailing from the Gulf of California to landings along the river that linked to wagon roads to the interior. Starting in the 1860s, gold and silver strikes drew prospectors to the upper Colorado River basin. Large-scale river management began in the early 1900s, with major guidelines established in
