The Yeso Group is a group of geologic formations in New Mexico . It contains fossils characteristic of the Kungurian Age of the early Permian Period .
16-614: Elephant Butte may refer to: Summits [ edit ] Elephant Butte (Monument Valley) , Arizona Elephant Butte (Hidalgo County, New Mexico) Elephant Butte (Sierra County, New Mexico) , a volcanic neck surrounded by a lake Elephant Butte (Montana) , a mountain in Garfield County Elephant Butte (Arches National Park) , highest point in Arches National Park Elephant Butte (Washington) ,
32-665: A member of the Chupadera Formation in 1922, but Needham and Bates returned it to its original designation as a formation within the Manzano Group in 1943. Needham and Bates also removed the Glorieta Sandstone from the formation. Kelley and Wood divided the formation into members in 1946, including the lowermost Mesita Blanca Member. Baars pointed out in 1962 that the Meseta Blanca Member is indistinguishable from
48-617: A mountain in Whatcom County Other places [ edit ] Elephant Butte Reservoir , a reservoir on the Rio Grande , in New Mexico . Elephant Butte, New Mexico , a city Elephant Butte, Sierra County, New Mexico , a populated place See also [ edit ] White Elephant Butte [REDACTED] Topics referred to by the same term This disambiguation page lists articles about distinct geographical locations with
64-698: A record of marine microfossils, mostly algae and foraminiferans, trace fossils (including tetrapod footprints), and terrestrial plant fossils. In 2018, a mold of an incomplete, articulated skeleton of a eupelycosaur was discovered in lower Yeso strata. The microfossils date the Yeso Group to the Kungurian . Tetrapod trackways have been found in the De Chelly Sandstone in the Lucero uplift. These are too poorly preserved for precise classification. Carbon dioxide
80-591: Is a 5,981-foot-elevation (1,823-meter) summit in Navajo County , Arizona , United States. Elephant Butte is situated 2.3 miles (3.7 km) southeast of the Monument Valley visitor center on Navajo Nation land. Precipitation runoff from this butte's slopes drains into Gypsum Creek which is a tributary of the San Juan River . Topographic relief is significant as the summit rises 900 feet (274 meters) above
96-525: Is generally light during the winter. De Chelly Sandstone The Yeso Group is lithologically complex, ranging from marine shelf carbonate rock to the south through shoreline and sabkha beds to eolian dune and sheet sand deposits to the north. It is exposed in the mountains and other uplifts bordering the Rio Grande Rift and in the Pecos River valley. It is present in the subsurface in
112-504: Is slope-forming Organ Rock Shale , the next stratum is cliff-forming De Chelly Sandstone , and the upper layer is Moenkopi Formation . The rock ranges in age from Permian at the bottom to Early Triassic at the top. The buttes and mesas of Monument Valley are the result of the Organ Rock Shale being more easily eroded than the overlaying sandstone. Spring and fall are the most favorable seasons to visit Elephant Butte. According to
128-611: The Köppen climate classification system, it is located in a semi-arid climate zone with cold winters and hot summers. Summers average 54 days above 90 °F (32 °C) annually, and highs rarely exceed 100 °F (38 °C). Summer nights are comfortably cool, and temperatures drop quickly after sunset. Winters are cold, but daytime highs are usually above freezing. Winter temperatures below 0 °F (−18 °C) are uncommon, though possible. This desert climate receives less than 10 inches (250 millimeters) of annual rainfall, and snowfall
144-533: The Raton Basin . The group records a major marine transgression from the south during the early Leonardian (Kungurian). In the Jemez Mountains , the group consists of massive cross-bedded lower beds ( De Chelly Sandstone ) and thinner upper beds ( San Ysidro Formation ) suggesting a more fluvial depositional environment. The Yeso Group is exposed extensively in the Jemez Mountains , but pinches out in
160-732: The Earth's mantle and the Yeso Group is merely a reservoir rock. Carbon dioxide accumulates in the Tubb Sandstone Member (sometimes also known as the Drinkard Sandstone ) and is capped by the Cimarron Anhydrite Member. The unit was designated as the Yeso Formation of the (now-abandoned) Manzano Group by W.T. Lee in 1909 for Mesa del Yeso, a small mesa 12 miles northeast of Socorro, New Mexico . Darton redesignated it as
176-613: The Torres is 180 metres (590 ft) of gypsiferous siliclastic sedimentary rock and gypsum with minor dolomite; the Cañas is 16 to 52 metres (52 to 171 ft) of mostly gypsum; and the Joyita Member is 21 metres (69 ft) of redbed sandstone. The group is conformable with both the underlying Abo Formation and the overlying Glorieta Sandstone . The Yeso Group is largely devoid of fossils. However, continued field work has gradually built up

#1732855376417192-457: The northern Jemez, delineating the northern limit of the dune field from which it arose. Farther south, the group is divided into the Arroyo de Alamillo and Los Vallos Formations. It transitions from continental to shallow marine in character from north to south, with the lithology changing from eolian and sand sheet deposits in the north to sabkha deposits of gypsum and carbonate rock to

224-692: The south. Thus the Arroyo de Alamillo Formation is siltstone, ripple-laminated sandstone, and lesser dolomitic limestone, in contrast with the eolian beds of the De Chelly Formation, and the Los Vallos Formation is 42% sandstone, 28% siltstone, and 24% gypsum , in contrast with the thinly bedded sandstone of the San Ysidro Formation. The Los Vallos Formation is divided into the Torres, Cañas and Joyita Members. At Abo Pass in central New Mexico,
240-433: The surrounding terrain in 0.25 mile (0.4 km). The nearest higher neighbor is Three Sisters , 1.4 miles (2.3 km) to the southwest. The landform's toponym has been officially adopted by the U.S. Board on Geographic Names , and the descriptive name refers to the resemblance of an elephant's profile viewed from a south perspective. Elephant Butte is a butte composed of three principal strata. The bottom layer
256-507: Was produced from subsurface Yeso beds in the Bueyeros, New Mexico field. Production was limited from 1931 to 1980, but increased demand for carbon dioxide for enhanced oil recovery led to construction of pipelines to the Permian Basin . Production totaled 3.3 trillion ft by 2018, with an estimated 5 to 10 trillion ft still recoverable. Isotope studies suggest the carbon dioxide originated in
