75-754: The Organ Mountains are near the southern end of a long line of mountains on the east side of the Rio Grande 's rift valley . The range is nearly contiguous with the San Andres Mountains to the north and the Franklin Mountains to the south, but is very different geologically: whereas the San Andres and Franklin Mountains are both formed from west-dipping fault blocks of mostly sedimentary strata (with limestone most prominent),

150-661: A channel was dug for flood control which moved the river, creating what was called Cordova Island, which became the center of the Chamizal dispute . Resolving the dispute took many years and resulted in a 1909 combined assassination attempt on the American and Mexican presidents. Following the approval of the Rio Grande Project by federal lawmakers in 1905, the waters of the Rio Grande were to be divided between

225-584: A healthy speaker base; however, because of efforts to preserve the language starting in the 1980s—both by native speakers and linguists—this problem is not as dire as it for some other indigenous languages. Tewa has a fairly large phoneme inventory with 45 distinct individual sounds. Twelve of these are vowels, which can be either long or short. Tewa, like other Tanoan languages, also makes use of tones, of which it has four. The 1980 census counted 1,298 speakers, almost all of whom are bilingual in English. Today,

300-409: A large swing bridge , dates back to 1910 and is still in use today by automobiles connecting Brownsville with Matamoros, Tamaulipas . The swing mechanism has not been used since the early 1900s, though, when the last of the big steamboats disappeared. At one point, the bridge also had rail traffic. Railroad trains no longer use this bridge. A new rail bridge (West Rail International Crossing) connecting

375-547: A playa in the southern Albuquerque Basin where it deposited the Popotosa Formation . The upper reach of this river corresponded to the modern Rio Chama , but by 5 million years ago, an ancestral Rio Grande draining the eastern San Juan Mountains had joined the ancestral Rio Chama. The ancestral Rio Grande progressively integrated basins to the south, reaching the Mesilla Basin by 4.5 million years and

450-595: A royal Spanish cartographer. In the autumn of 1540, a military expedition of the Viceroyalty of New Spain led by Francisco Vásquez de Coronado , Governor of Nueva Galicia , reached the Tiwa pueblos along the Rio Grande in the future New Mexico . On July 12, 1598, Don Juan de Oñate y Salazar established the New Spain colony of Santa Fe de Nuevo Méjico at the new village of San Juan de los Caballeros adjacent to

525-606: A single river system draining into the Gulf of Mexico until relatively recent geologic time. Instead, the basins formed by the opening of the Rio Grande rift were initially bolsons , with no external drainage and a central playa . An axial river existed in the Espanola Basin as early as 13 million years ago, reaching the Santo Domingo Basin by 6.9 million years ago. However, at this time, the river drained into

600-420: A small, sandy delta at the Gulf of Mexico. During portions of 2001 and 2002, the mouth of the Rio Grande was blocked by a sandbar. In the fall of 2003, the sandbar was cleared by high river flows around 7,063 cubic feet per second (200 m /s). The Rio Grande flows through a valley with diverse animal and plants communities. Conservation of the river and the valley is a recurring theme for people who live in

675-400: A word, sometimes be the addition of a word superfix. Within free roots, there are two additional types, isolated and non-isolated free roots. There is a very small number of isolated free roots, as these are roots that are neither combinable with other roots nor affixable. Non-isolated free roots are roots that are combinable with other roots and/or are affixable. A limited non-isolated free root

750-533: A year later, in October 2022, the reservoir had made only insignificant rebounds, resting at 6.4% of capacity. In late July 2022, due to extreme drought, the Rio Grande ran dry for about 50 miles in the middle Rio Grande Valley , including five miles in Albuquerque, the first time it had done so in over 40 years. The following winter, the basin experienced above-average snowfall, leading to very high flows in

825-452: Is affixed with set marker /-n/, and class non-N, which does not have this affix. Class non-N is the larger of the two, containing almost all nouns in Tewa, which are, for the most part, mono- or di-syllabic. Class N nouns are mostly designations for age-sex differentiation, kinship terms, and forms which translate as pronouns. All known noun affixes are included in the chart below. /-n2/

900-524: Is better in flanking basins of the Rio Grande Valley, where numerous Folsom sites and a much smaller number of earlier Clovis sites have been identified. Later Paleo-Indian groups included the Belen and Cody cultures, who appear to have taken advantage of the Rio Grande Valley for seasonal migrations and may have settled more permanently in the valley. The Paleo-Indian cultures gave way to

975-597: Is defined as "severely endangered" in New Mexico by UNESCO. In the names "Pojoaque" and "Tesuque", the element spelled "que" (pronounced something like [ɡe] in Tewa, or /ki/ in English) is Tewa for "place". Tewa can be written with the Latin script ; this is occasionally used for such purposes as signs ( Be-pu-wa-ve ' Welcome ' , or sen-ge-de-ho ' Bye ' ). Because alphabet systems have been developed in

1050-730: Is different from /-n/ because of the occurrence of /-n2/ with singular, dual, and plural situations involving the same root, which is never the case for /-n/. Class Z words are neither particles, verbs, or nouns. They are affixable with suffixes like /-á/, /-ân/, /-bo/, and /-ho'/, /-reʔ/, /-an/, /-we/, and /-ge/, but unlike nouns and verbs they do not occur with the specific affixes which delineate those classes (/wé:-/ or /pi-/ and /-ví/ respectively). These compromise words whose English equivalents involve time, location, manner, interrogation, etc. Tewa sentences follow subject-object-verb order, however there are simple sentences in Tewa such as " handiriho gi-c'u " (that's how we got in) which are simply

1125-537: Is entirely within Fort Bliss and closed to the general public. President Obama designated the Organ Mountains–Desert Peaks a national monument by executive authority on Wednesday, May 21, 2014. White House press secretary Jay Carney stated that "By establishing the monument, the president will permanently protect more than 496,000 acres to preserve the prehistoric, historic and scientific values of

1200-548: Is not part of the Water Authority's long-term resource management plan, dubbed WATER 2120. Dams on the Rio Grande include Rio Grande Dam , Cochiti Dam , Elephant Butte Dam , Caballo Dam , Amistad Dam , Falcon Dam , Anzalduas Dam , and Retamal Dam . In southern New Mexico and the upper portion of the Texas border segment, the river's discharge dwindles. Diversions, mainly for agricultural irrigation, have increased

1275-439: Is one which can combine only with affixes, but not with other roots. A universal non-isolated free root is one which can combine both with other roots and affixes. Bound roots are defined as those roots which cannot be converted directly into a word. Tewa has 15 types of verbs, and a few example verbs and their conjugations are shown below. Verbs can be divided into two classes, S and A, standing for stative and active, based of

1350-501: Is some disagreement among the Tewa people about whether or not Tewa should have a written form, as some Pueblo elders believe that their language should be preserved by oral tradition alone. Because of this, it was not until the 1960s that the language was written down for the first time. However, many Tewa speakers have decided that Tewa literacy is an important aspect in passing down the language and so orthographies have been created for this purpose. The language has struggled to maintain

1425-625: Is unavailable for storage, reducing system capacity by about 180,000 acre-feet. MRGCD has requested storage of "native water" downstream at Abiquiu Reservoir , which normally only stores waters imported into the Rio Grande watershed from the Colorado River watershed via the San Juan–Chama Project . Elephant Butte Reservoir , the main storage reservoir on the Rio Grande, was reported at 13.1% of capacity as of May 1, 2022, further decreasing to only 5.9% full by November 2021. Nearly

1500-705: The Archaic Oshara tradition beginning around 5450 BCE. The Oshara began cultivation of maize between 1750 and 750 BCE, and their settlements became larger and more permanent. Drought induced the collapse of the Ancestral Puebloan culture, at Chaco Canyon and elsewhere across the Four Corners region, at around 1130 CE. This led to a mass migration of the Ancestral Puebloans to the Rio Grande and other more fertile valleys of

1575-822: The Colorado River basin via the San Juan-Chama Diversion Project and from the Rio Chama . The Rio Grande then continues southwards, irrigating the farmlands in the Middle Rio Grande Valley through the desert cities of Albuquerque and Las Cruces in New Mexico, to El Paso, Texas and Ciudad Juárez, Chihuahua , in Mexico. In the Albuquerque metropolitan area , the Rio Grande flows by historic Pueblo villages, such as Sandia Pueblo and Isleta Pueblo . South of El Paso,

The length of the Rio Grande is 1,896 miles (3,051 km), making it the 4th longest river in the United States and in North America by main stem. It originates in south-central Colorado , in the United States, and flows to the Gulf of Mexico . The Rio Grande drainage basin (watershed) has an area of 182,200 square miles (472,000 km ); however,

1725-559: The Endangered Languages Project estimates a total of 1,500 speakers worldwide, with 1,200 of them in the New Mexico pueblos and 300 in the Arizona village of Hano. Of these speakers, few are fluent with the vast majority being semi-speakers, and only in a few places, like Hano, are children acquiring Tewa. The largest New Mexico pueblo, San Juan, there are only 30 fluent speakers left as of 2008. As of 2012, Tewa

1800-579: The International Boundary and Water Commission (IBWC), US–Mexico. The most notable of these treaties were signed in 1906 and 1944. The IBWC traces its institutional roots to 1889, when the International Boundary Committee was established to maintain the border. The IBWC today also allocates river waters between the two nations and provides for flood control and water sanitation. Use of that water belonging to

1875-642: The Ohio and Mississippi Rivers were requisitioned by the U.S. government and moved to the Rio Grande during the Mexican–American War in 1846. They provided transport for the U.S. Army, under General Zachary Taylor , to invade Monterrey , Nuevo León , via Camargo Municipality, Tamaulipas . Army engineers recommended that with small improvements, the river could easily be made navigable as far north as El Paso. Those recommendations were never acted upon. The Brownsville & Matamoros International Bridge ,

1950-595: The Ohkay Owingeh Pueblo at the confluence of the Rio Grande and the Río Chama . During the late 1830s and early 1840s, the river marked the disputed border between Mexico and the nascent Republic of Texas ; Mexico marked the border at the Nueces River . The disagreement provided part of the rationale for the Mexican–American War in 1846, after Texas had been admitted as a new state. Since 1848,

2025-643: The Pecos River and Devils River , both entering the Rio Grande from the north in the vicinity of Amistad Reservoir in Texas, and the Rio Salado and Rio San Juan both entering from the south with confluences in Tamaulipas , Mexico. The Rio Grande rises in high mountains and flows for much of its length at high elevation; the valley floor at Albuquerque is 5,312 feet (1,619 m), and El Paso 3,762 feet (1,147 m) above sea level . In New Mexico,

2100-655: The Pueblo and Navajo peoples also have had names for the Rio Grande/Rio Bravo: The four Pueblo names likely antedated the Spanish entrada by several centuries. Rio del Norte was most commonly used for the upper Rio Grande (roughly, within the present-day borders of New Mexico) from Spanish colonial times to the end of the Mexican period in the mid-19th century. This use was first documented by

2175-773: The Rio Grande Gorge , and fully reintegrated the San Luis Basin into the Rio Grande watershed. Archeological sites from the earliest human presence in the Rio Grande Valley are scarce, due to traditional Indigenous nomadic culture, Pleistocene and Holocene river incision or burial under the Holocene floodplain. However, some early sites are preserved on West Mesa on the west side of the Rio Grande near Albuquerque. These include Folsom sites, possibly dating from around 10,800 to 9,700 BCE, that were probably short-term sites such as buffalo kill sites. Preservation

2250-477: The US Navy . It was a shallow-draft river port, with several smaller vessels that hauled cargo to and from the deeper-draft cargo ships anchored off shore. These deeper-draft ships could not cross the shallow sandbar at the mouth of the river. The port's commerce was European military supplies, in exchange for bales of cotton. The sedimentary basins forming the modern Rio Grande Valley were not integrated into

2325-411: The endorheic basins that are adjacent to and within the greater drainage basin of the Rio Grande increase the total drainage-basin area to 336,000 square miles (870,000 km ). The Rio Grande with its fertile valley , along with its tributaries, is a vital water source for seven US and Mexican states, and flows primarily through arid and semi-arid lands. After traversing the length of New Mexico ,

2400-441: The southwestern willow flycatcher . The water of the Rio Grande is over-appropriated: that is, more users for the water exist than water in the river. Because of both drought and overuse, the section from Las Cruces downstream through Ojinaga frequently runs dry and was recently tagged "The Forgotten River" by those wishing to bring attention to the river's deteriorated condition. In 2022, due to increasing drought and water use,

2475-558: The 1890s, the Rio Grande flowed through Las Cruces from February to October each year, but this is subject to climate change. In 2020, the river flowed only from March to September. As of January 2021, the Elephant Butte Irrigation District (Ebid) expected that water shortages would mean the river only flows through Las Cruces from June through July. The water shortages are affecting the local ecosystem and endangering species including cottonwood trees and

2550-774: The Brownsville and Matamoros Bridge Company, a joint venture between the Mexican government and the Union Pacific Railroad . At the mouth of the Rio Grande, on the Mexican side, was the large commercial port of Bagdad, Tamaulipas . During the American Civil War , this was the only legitimate port of the Confederacy. European warships anchored offshore to maintain the port's neutrality, and managed to do so successfully throughout that conflict, despite occasional stare-downs with blockading ships from

2625-700: The Organ Mountains are made primarily of igneous rock (intrusive granite and extrusive rhyolite ). Their name reflects their similarity in appearance (particularly the granite "needles" in the highest part of the range) with pipes that would be part of a pipe organ . The San Andres Mountains (southern subrange of San Augustin Mountains ) are separated from the Organ Mountains by San Augustin Pass , through which U.S. Highway 70 passes on its way to White Sands Missile Range , White Sands National Park and Alamogordo . The Franklin Mountains are separated from

River capture by a tributary of the Pecos River then occurred, with the Rio Grande flowing to Texas by 2.06 million years, and finally joining the Pecos River 800,000 years ago, which drained into the Gulf of Mexico. Volcanism in the Taos Plateau reduced drainage from the San Luis Basin until a spillover event 440,000 years ago that drained Lake Alamosa , forming

2850-472: The Rio Grande becomes the Mexico–United States border , between the U.S. state of Texas and the northern Mexican states of Chihuahua and Coahuila , Nuevo León and Tamaulipas ; a short segment of the Rio Grande is a partial state-boundary between the U.S. states of New Mexico and Texas. Since the mid–twentieth century, only 20 percent of the Rio Grande's water reaches the Gulf of Mexico, because of

Though both Colorado and New Mexico were initially eager to begin negotiations, they broke down over whether Texas should be allowed to join negotiations in 1928, though it had representatives present. In an effort to avoid litigation of

3075-401: The Rio Grande has marked the boundary between Mexico and the United States from the twin cities of El Paso , Texas, and Ciudad Juárez , Chihuahua, to the Gulf of Mexico. As such, crossing the river was the escape route used by some Texan slaves to seek freedom. Mexico had liberal colonization policies and had abolished slavery in 1828. In 1899, after a gradual change to the river position,

3150-498: The Rio Grande is the national border between the U.S. and Mexico. The segment of the river that forms the international border ranges from 889 to 1,248 miles (1,431 to 2,008 km), depending on how the river is measured. The Rio Conchos is a major tributary of the Rio Grande, with its confluence 310 km. (193 straight air miles) southeast of El Paso near Ojinaga , in Chihuahua , Mexico. Downstream, other tributaries include

3225-530: The Rio Grande's discharge increases to its maximum annual average of 3,504 cubic feet per second (99 m /s) near Rio Grande City. Large diversions for irrigation below Rio Grande City reduce the river's average flow to 889 cubic feet per second (25 m /s) at Brownsville and Matamoros. The major international border crossings along the river are at Ciudad Juárez and El Paso ; Presidio and Ojinaga; Laredo and Nuevo Laredo ; McAllen and Reynosa ; and Brownsville and Matamoros. Other notable border towns are

3300-784: The Southwest, competing with other indigenous communities such as the Apache with territory in the Rio Grande Valley. This led to decades of conflict (the Coalition Period), the eventual merging of cultures, and the establishment of most of the Tanoan and Keresan pueblos of the Rio Grande Valley. This was followed by the Classic Period, from about 1325 CE to 1600 CE and the arrival of the Spanish. The upper Rio Grande Valley

3375-483: The Spanish in 1582. Early American settlers in South Texas began to use the modern 'English' name Rio Grande. By the late 19th century, in the United States, the name Rio Grande had become standard in being applied to the entire river, from Colorado to the sea. By 1602, Río Bravo had become the standard Spanish name for the lower river, below its confluence with the Rio Conchos. The largest tributary of

The most prominent of these was R.L Ingraham, whose Guide to Climbing in the Organ Mountains remains a definitive reference. The Bureau of Land Management maintains hiking trails accessed from four sites in the Organ Mountains: The southern limestone section is difficult to access and rarely visited. Bishop's Cap can be reached through rugged dirt roads, but has no developed trails. Rattlesnake Ridge

4050-469: The findings of which helped lead to the final agreement. The 1938 Rio Grande Compact provided for the creation of a compact commission, the creation of gaging stations along the river to ensure flow amounts by Colorado to New Mexico at the state line and by New Mexico to Elephant Butte Reservoir , the water once there would fall under the regulation of the Rio Grande Project which would guarantee provision to Texas and Mexico. A system of debits and credits

Roots also tend to show heavier stress than affixes if each is the same syllable and tone type. A stronger stress is associated with a higher tone and greater vowel length. However, because of the complex use of tone, syllable type, and contour segments more research does need to be done. Tewa has what are called both "free" and "bound" roots. Free roots are defined as those roots which can be converted directly into

5325-548: The water debt owed to Texas increased from 31,000 acre-feet to over 130,000 acre-feet since 2021, despite "very significant efforts that were done on the river this year to keep water flowing downstream." In response, New Mexico increased its program offering to subsidize farmers who fallow their fields rather than planting crops, which uses additional water; the city of Albuquerque shut off its domestic supply diversion and switched to full groundwater pumping in 2021. Additionally, in 2022, work began on El Vado Dam , during which it

In 1519, a Spanish naval expedition along the northeastern coast of Mexico charted the mouths of several rivers including the Rio Grande. In 1536, the Rio Grande appeared for the first time on a map of New Spain produced by

5550-460: Was created to account for variations in the water provided. The compact remains in effect today, though it has been amended twice. In 1944, the US and Mexico signed a treaty regarding the river. Due to drought conditions which have prevailed throughout much of the 21st century, calls for a reexamination of this treaty have been made by locals in New Mexico, Mexico, and Texas. Texas, being the state with

5625-694: Was initiated by legislation signed by President John F. Kennedy in 1962, and was completed in 1971. This diversion project transports water under the continental divide from tributaries of the San Juan River (the Navajo, the Little Navajo, and Blanco Rivers) to Heron Reservoir, which empties into the Rio Chama before this connects to the Rio Grande. Although it held rights to San Juan-Chama water for many years, it wasn't until 2008 that Albuquerque began using it as part of its municipal supply, with
