Lake Manly
Lake Manly was a pluvial lake in Death Valley, California, covering much of Death Valley with a surface area of during the so-called "Blackwelder stand". 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 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. In Death Valley, lakes existed during different times in the geological past. After some poorly defined lake stages during the Miocene, Pliocene and early Pleistocene, the first large lake stage occurred about 185,000–128,000 years ago ...

Death Valley
Death Valley is a desert valley in Eastern California, in the northern Mojave Desert, bordering the Great Basin Desert. During summer, it is the Highest temperature recorded on Earth, hottest place on Earth. Death Valley's Badwater Basin is the point of lowest elevation in North America, at below sea level. It is east-southeast of Mount Whitney — the highest point in the contiguous United States, with an elevation of 14,505 feet (4,421 m). On the afternoon of July10, 1913, the National Weather Service, United States Weather Bureau recorded a high temperature of 134 °F (56.7 °C) at Furnace Creek, California, Furnace Creek in Death Valley, which stands as the Highest temperature recorded on Earth, highest ambient air temperature ever recorded on the surface of the Earth. This reading, however, and several others taken in that period are disputed by some modern experts. Lying mostly in Inyo County, California, near the border of California and Nevada, in the Great ...

Lake Mojave
Lake Mojave is an ancient former lake fed by the Mojave River that, through the Holocene, occupied the Silver Lake and Soda Lake basins in the Mojave Desert of San Bernardino County, California. Its outlet may have ultimately emptied into the Colorado River north of Blythe. Geography Lake Mojave existed in San Bernardino County. The city of Las Vegas lies northeast of Lake Mojave. On the western side, Lake Mojave was bordered by mountains that steeply rise from the basin. The eastern side is more gentle, featuring alluvial fans and pediment. The lake At its maximum stand, Lake Mojave had a surface area of and a volume of . Lake Mojave had two separate lake level stands, the A stand and the B stand. The A stand lies at an altitude of above sea level and the B stand at an altitude of . The lake was about deep. 15 alluvial fans abut the shores of Lake Mojave that face the Soda Mountains. A present-day bay exists on the northwestern side of the Silver Lake basin and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Manix
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 and reached an altitude of at highstands, although poorly recognizable shorelines have been found at altitudes of . 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. The lake formed about 500,000 years before present, when the Mojave River left the Victorville area and started to drain into Manix and Lake Harper. The lake did not immediately include the Afton basin; its integration occurred only about 190,000 years ago, most likely due to a catastrophic flood. Lake Manix lasted until 25,000–13,800 years ago, when Afton ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Dumont
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Panamint
Lake Panamint (also known as Lake Gale) 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. Geography and geomorphology The lake developed within Panamint Valley, California. This valley is a north–south trending depression that is bound between the Panamint Range in the northeast and the Argus Range- Slate Range in the west-southwest. The town of Ballarat lies in the valley, and California State Route 190 crosses the former lake basin in its northern sector. The existence of a lake in this valley was first postulated in 1914. Lake Panamint was about long and wide, making it a long and narrow lake. Both the main inlet and the potential outlet were located in a narrower southern part. The total water volume was about . The lake consisted o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Searles Lake
Searles Lake is an endorheic dry lake in the Searles Valley of the Mojave Desert, in northwestern San Bernardino County, California. The lake in the past was also called Slate Range Lake and Borax Lake. The mining community of Trona is on its western shore. The evaporite basin is approximately long and at its widest point, yielding 1.7 million tons annually of industrial minerals within the basin to the Searles Valley Minerals mining operations. Searles Lake is bounded by the Argus and Slate Mountains. Named after John Wemple Searles. Geology The stratigraphic record at Searles Lake shows that it once held brackish water as deep as . Fluctuations in lake levels correspond to the advances and retreats of glaciers in the Sierra Nevada Range. Thirty major lake levels occurred during the last 150,000 years, represented by a sequence of salt and mud beds. The precipitation of minerals occurred during long periods of lake evaporation. The lake is home to the Trona Pinnacle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Owens Lake
Owens Lake is a mostly dry lake in the Owens Valley on the eastern side of the Sierra Nevada in Inyo County, California. It is about south of Lone Pine, California. Unlike most dry lakes in the Basin and Range Province that have been dry for thousands of years, Owens held significant water until 1913, when much of the Owens River was diverted into the Los Angeles Aqueduct, causing Owens Lake to desiccate by 1926. A 2004 court order required the LADWP to reestablish a small flow from the river into the lake. Nevertheless, as of 2013, it is the largest single source of dust pollution in the United States. History Owens Lake was given its present name by the explorer John C. Frémont, in honor of one of his guides, Richard Owens. Owens himself never set foot in the valley. The lake's original name, given by the ''Nüümü'' (Owens Valley Paiute), is ''Patsiata''. Before the diversion of the Owens River, Owens Lake was up to long and wide, covering an area of up to .

Mono Lake
Mono Lake ( ) is a saline soda lake in Mono County, California, formed at least 760,000 years ago as a terminal lake in an endorheic basin. The lack of an outlet causes high levels of salts to accumulate in the lake which make its water alkaline. The desert lake has an unusually productive ecosystem based on brine shrimp, which thrive in its waters, and provides critical habitat for two million annual migratory birds that feed on the shrimp and alkali flies ('' Ephydra hians''). Historically, the native Kutzadika'a people ate the alkali flies' pupae, which live in the shallow waters around the edge of the lake. When the city of Los Angeles diverted water from the freshwater streams flowing into the lake, it lowered the lake level, which imperiled the migratory birds. The Mono Lake Committee formed in response and won a legal battle that forced Los Angeles to partially replenish the lake level. Geology Mono Lake occupies part of the Mono Basin, an endorheic basin that has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tecopa Lake Beds
The Tecopa Lake Beds is a Blancan Pleistocene geologic formation in the Mojave Desert in eastern California. It is in the Tecopa area, east of Death Valley, in southeastern Inyo and northeastern San Bernardino County. The Lake Tecopa lake beds are the dry lake remnant of the formerly huge Pleistocene age Lake Tecopa, in the present day Amargosa River basin. It preserves fossils of the Quaternary period in the Cenozoic Era. Among the fossils found in the Tecopa Lake Beds is '' Capricamelus gettyi'', a camelid.

Ice Age
An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet. Earth is currently in the Quaternary glaciation. Individual pulses of cold climate within an ice age are termed ''glacial periods'' (or, alternatively, ''glacials, glaciations, glacial stages, stadials, stades'', or colloquially, ''ice ages''), and intermittent warm periods within an ice age are called '' interglacials'' or ''interstadials''. In glaciology, ''ice age'' implies the presence of extensive ice sheets in both northern and southern hemispheres. By this definition, Earth is currently in an interglacial period—the Holocene. The amount of anthropogenic greenhouse gases emitted into Earth's oceans and atmosphere is predicted to prevent the next glacial period for th ...

Lake Bonneville
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. Geologic description Shorelines of Lake Bonneville are visible above Salt Lake City along the western front of the Wasatch Mountains and on other mountains throughout the Bonneville basin.Gilbert, G.K., 1890. Lake Bonneville. U.S. Geological Survey Monograph 1. 438 pp. These shorelines appear as shelves or benches that protrude from the mountainside above the valley floor, are visible on the ground from long distances and on satellite images, and have both de ...

Lake Lahontan
Lake Lahontan was a large endorheic Pleistocene lake of modern northwestern Nevada that extended into northeastern California and southern Oregon. The area of the former lake is a large portion of the Great Basin that borders the Sacramento River watershed to the west. The lake was named by Clarence King during the Geological Exploration of the Fortieth Parallel. The name honors Louis-Armand de Lom d'Arce de Lahontan, Baron de Lahontan, a French soldier and explorer. History At its peak approximately 12,700 years ago (during a period known as the Sehoo Highstand), the lake had a surface area of over , with its largest component centered at the location of the present Carson Sink. The depth of the lake was about at present day Pyramid Lake, and at the Black Rock Desert. Lake Lahontan, during this most recent glacial period, would have been one of the largest lakes in North America. Climate change around the end of the Pleistocene epoch led to a gradual desiccation of anc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
