Lake Bonneville was the largest Late Pleistocene paleolake in the Great Basin of western North America. It was a pluvial lake that formed in response to an increase in precipitation and a decrease in evaporation as a result of cooler temperatures. The lake covered much of what is now western Utah and at its highest level extended into present-day Idaho and Nevada. Many other hydrographically closed basins in the Great Basin contained expanded lakes during the Late Pleistocene, including Lake Lahontan in northwestern Nevada.
The Mojave Desert is a desert in the rain shadow of the southern Sierra Nevada mountains and Transverse Ranges in the Southwestern United States. Named for the indigenous Mohave people, it is located primarily in southeastern California and southwestern Nevada, with small portions extending into Arizona and Utah.
Harper Lake is a dry lake located in the Mojave Desert near the small community of Lockhart, California, in northwestern San Bernardino County of Southern California. The lake is accessible from Harper Lake Road, which runs north off of State Route 58 midway between Boron and Barstow.
Lake Manix is a former lake fed by the Mojave River in the Mojave Desert. It lies within San Bernardino County, California. Located close to Barstow, this lake had the shape of a cloverleaf and covered four basins named Coyote, Cady/Manix, Troy and Afton. It covered a surface area of 236 square kilometres (91 sq mi) and reached an altitude of 543 metres (1,781 ft) at highstands, although poorly recognizable shorelines have been found at altitudes of 547–558 metres (1,795–1,831 ft). The lake was fed by increased runoff during the Pleistocene and overflowed into the Lake Mojave basin and from there to Lake Manly in Death Valley, or less likely into the Bristol Lake basin and from there to the Colorado River.
Tuyajto Lake is a salt lake located in the Antofagasta Region, northern Chile. Located at an elevation of about 4,010 metres (13,160 ft), its surface area presently fluctuates between 1.7–2.7 square kilometres (0.66–1.04 sq mi) but in the past it was considerably larger; this led to humans going to the lake and creating archeological sites there. Presently, the lake is groundwater-fed and has no surface outlet but water might seep out underground. It is part of the Los Flamencos Natural Reserve.
Lake Tauca is a former lake in the Altiplano of Bolivia. It is also known as Lake Pocoyu for its constituent lakes: Lake Poopó, Salar de Coipasa and Salar de Uyuni. The lake covered large parts of the southern Altiplano between the Eastern Cordillera and the Western Cordillera, covering an estimated 48,000 to 80,000 square kilometres of the basins of present-day Lake Poopó and the Salars of Uyuni, Coipasa and adjacent basins. Water levels varied, possibly reaching 3,800 metres (12,500 ft) in altitude. The lake was saline. The lake received water from Lake Titicaca, but whether this contributed most of Tauca's water or only a small amount is controversial; the quantity was sufficient to influence the local climate and depress the underlying terrain with its weight. Diatoms, plants and animals developed in the lake, sometimes forming reef knolls.
Lake Corcoran is an ancient lake that covered the Central Valley of California.
Lake Cahuilla was a prehistoric lake in California and northern Mexico. Located in the Coachella and Imperial valleys, it covered surface areas of 5,700 km2 (2,200 sq mi) to a height of 12 m (39 ft) above sea level during the Holocene. During earlier stages of the Pleistocene, the lake reached even higher elevations, up to 31–52 m (102–171 ft) above sea level. During the Holocene most of the water came from the Colorado River with little contribution from local runoff; in the Pleistocene local runoff was higher and it is possible that Lake Cahuilla was supported solely from local water sources during the Wisconsin glaciation. The lake overflowed close to Cerro Prieto into the Rio Hardy, eventually draining into the Gulf of California.
Lake Manly is a pluvial lake in Death Valley, California. It forms occasionally in Badwater Basin after heavy rainfall, but at its maximum extent during the so-called "Blackwelder stand," ending approximately 120,000 years before present, the lake covered much of Death Valley with a surface area of 1,600 square kilometres (620 sq mi). Water levels varied through its history, and the chronology is further complicated by active tectonic processes that have modified the elevations of the various shorelines of Lake Manly; during the Blackwelder stage they reached 47–90 metres (154–295 ft) above sea level. The lake received water mainly from the Amargosa River and at various points from the Mojave River and Owens River. The lake and its substantial catchment favoured the spread of a number of aquatic species, including some lizards, pupfish and springsnails. The lake probably supported a substantial ecosystem, and a number of diatoms developed there.
Kelso Wash is an ephemeral stream in San Bernardino County, California, United States, that drains into Soda Lake. The town of Kelso lies southeast of the wash.
Lake Palomas is a former lake in New Mexico, United States, and Chihuahua, Mexico. This lake was relatively large and reached a size of about 9,100 square kilometres (3,500 sq mi) during its highstands. Preceded by Lake Cabeza de Vaca, it formed during the Pleistocene and continued into the Holocene, when several different lake phases occurred. Presently its basin is a major source of airborne dust in the region.
Neopluvial is a term referring to a phase of wetter and colder climate that occurred during the late Holocene in the Western United States. During the Neopluvial, water levels in a number of now-dry lakes and closed lakes such as the Great Salt Lake rose and vegetation changed in response to increased precipitation. The event was not exactly synchronous everywhere, with neopluvial lake-level rises occurring between 6,000 and 2,000 years ago. It is correlative to the Neoglacial period.
Lake Thompson is a former lake in California. The name is derived from an academic who first speculated on the possibility that a lake existed in lower Antelope Valley. It occupied the area of the lower Antelope Valley and of the lakes Rogers Lake and Rosamond Lake during the Pleistocene. It dried up during the Holocene.
Cima volcanic field is a volcanic field in San Bernardino County, California, close to the border with Nevada. The volcanic field covers a surface area of 600 km2 (230 sq mi) within the Mojave National Preserve west of the Cima Dome and consists of about 40 volcanic cones with about 60 lava flows. The volcanic cones range from simple cones over multi-cratered mountains to eroded hills, and lava flows are up to 9.1 km (5.7 mi) long. At least one lava tube exists in the field and can be visited.
Lake Panamint is a former lake that occupied Panamint Valley in California during the Pleistocene. It was formed mainly by water overflowing through the Owens River and which passed through Lake Searles into the Panamint Valley. At times, Lake Panamint itself overflowed into Death Valley and Lake Manly.
The African humid period is a climate period in Africa during the late Pleistocene and Holocene geologic epochs, when northern Africa was wetter than today. The covering of much of the Sahara desert by grasses, trees and lakes was caused by changes in the Earth's axial tilt; changes in vegetation and dust in the Sahara which strengthened the African monsoon; and increased greenhouse gases. During the preceding Last Glacial Maximum, the Sahara contained extensive dune fields and was mostly uninhabited. It was much larger than today, and its lakes and rivers such as Lake Victoria and the White Nile were either dry or at low levels. The humid period began about 14,600–14,500 years ago at the end of Heinrich event 1, simultaneously to the Bølling–Allerød warming. Rivers and lakes such as Lake Chad formed or expanded, glaciers grew on Mount Kilimanjaro and the Sahara retreated. Two major dry fluctuations occurred; during the Younger Dryas and the short 8.2 kiloyear event. The African humid period ended 6,000–5,000 years ago during the Piora Oscillation cold period. While some evidence points to an end 5,500 years ago, in the Sahel, Arabia and East Africa, the end of the period appears to have taken place in several steps, such as the 4.2-kiloyear event.
The Fazzan Basin, or Fezzan Basin, is a large endorheic basin in Libya. It has no outlet to the sea and contains large areas of desert or semi-arid land. It is one of two basins in southern Libya on the northern flanks of the Tibesti Mountains in the central Sahara desert, the other being the Kufra Basin, further to the east.
Lake Modoc is a former lake in California and Oregon, in the location of present-day Upper Klamath Lake, Lower Klamath Lake and Tule Lake. It existed during the Pliocene and Pleistocene epochs, its formation probably influenced by volcanism and faulting. The bed of the former lake had plentiful resources for early humans, and today it is used for agriculture.
Lake Estancia was a lake formed in the Estancia Valley, central New Mexico, which left various coastal landforms in the valley. The lake was mostly fed by creek and groundwater from the Manzano Mountains, and fluctuated between freshwater stages and saltier stages. The lake had a diverse fauna, including cutthroat trout; they may have reached it during a possible past stage where it was overflowing.
Lake San Agustín is a former lake in New Mexico, which developed as a pluvial lake in the Plains of San Agustín during Pleistocene glacial periods. During its highstands it covered an area of 1,200 square kilometres (460 sq mi) with a maximum depth of 70 metres (230 ft), and split into several separate lakes while drying out. The lake last appeared during the last glacial maximum (LGM) and dried out at the beginning of the Holocene, with the last remnant disappearing about 5,000 years ago.
