Avawatz Mountains
The Avawatz Mountains are located in San Bernardino County, California, in the Mojave Desert. Name There are several theories for the origin of the name Avawatz. It could be derived from the Mohave Indian term "Avi-Ahwat", or "red rock". Alternatively, the name comes from the Southern Paiute word ''iva-wätz'', meaning "white mountain sheep," or another Southern Paiute word, ''ávawatz'', meaning "gypsum". Geography The range lies to the west of State Route 127; between the Owlshead Mountains in the southern end of Death Valley National Park, and the Soda Mountains near the town of Baker. The range is at the intersection of the Garlock Fault and the Death Valley Fault Zone. As such, it is considered the southern end of the Walker Lane geologic trough. Part of the Avawatz Mountain range lies in the National Training Center, which is part of the Fort Irwin Military Reservation, and is closed to the public. The Avawatz Mountains reach an elevation of . References *Califor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Death Valley National Park
Death Valley National Park is an American national park that straddles the California–Nevada border, east of the Sierra Nevada. The park boundaries include Death Valley, the northern section of Panamint Valley, the southern section of Eureka Valley and most of Saline Valley. The park occupies an interface zone between the arid Great Basin and Mojave deserts, protecting the northwest corner of the Mojave Desert and its diverse environment of salt-flats, sand dunes, badlands, valleys, canyons and mountains. Death Valley is the largest national park in the contiguous United States, as well as the hottest, driest and lowest of all the national parks in the United States. It contains Badwater Basin, the second-lowest point in the Western Hemisphere and lowest in North America at below sea level. More than 93% of the park is a designated wilderness area. The park is home to many species of plants and animals that have adapted to this harsh desert environment including creos ...

Mountain Ranges Of The Mojave Desert
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain ...

Fort Irwin Military Reservation
Fort Irwin National Training Center (Fort Irwin NTC) is a major training area for the United States military in the Mojave Desert in northern San Bernardino County, California. Fort Irwin is at an average elevation of . It is located northeast of Barstow, in the Calico Mountains. The National Training Center is part of the US Army Forces Command (FORSCOM). The opposing force at the National Training Center is the 11th Armored Cavalry Regiment, the Blackhorse Cavalry, who are stationed at the base to provide an opposing force to units on a training rotation at Fort Irwin.

Trough (geology)
In geology, a trough is a linear structural depression that extends laterally over a distance. Although it is less steep than a trench, a trough can be a narrow basin or a geologic rift. These features often form at the rim of tectonic plates. There are various oceanic troughs on the ocean floors. Examples of oceanic troughs * Benue Trough * Cayman Trough * Kings Trough * Hesperides Trough * Nankai Trough * Northumberland Trough * Okinawa Trough in the East China Sea * Rockall Trough and others along the rift of the mid-oceanic ridge * Salton Trough The Salton Trough is an active tectonic pull-apart basin, or graben. It lies within the Imperial, Riverside, and San Diego counties of southeastern California, United States and extends south of the Mexico–United States border into the sta ... * South Shetland Trough * Suakin TroughDinwiddie, Robert et al.

Walker Lane
The Walker Lane is a geologic trough roughly aligned with the California/Nevada border southward to where Death Valley intersects the Garlock Fault, a major left lateral, or sinistral, strike-slip fault. The north-northwest end of the Walker Lane is between Pyramid Lake in Nevada and California's Lassen Peak where the Honey Lake Fault Zone, the Warm Springs Valley Fault, and the Pyramid Lake Fault Zone meet the transverse tectonic zone forming the southern boundary of the Modoc Plateau and Columbia Plateau provinces. The Walker Lane takes up 15 to 25 percent of the boundary motion between the Pacific Plate and the North American Plate, the other 75 percent being taken up by the San Andreas Fault system to the west. The Walker Lane may represent an incipient major transform fault zone which could replace the San Andreas as the plate boundary in the future. The Walker Lane deformation belt also accommodates nearly 12 mm/yr of dextral shear between the Sierra Nevada– ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Garlock Fault
The Garlock Fault is a left-lateral strike-slip fault running northeast–southwest along the north margins of the Mojave Desert of Southern California, for much of its length along the southern base of the Tehachapi Mountains. Geography Stretching for , it is the second-longest fault in California, and one of the most prominent geological features in the southern part of the state. It marks the northern boundary of the area known as the Mojave Block, as well as the southern ends of the Sierra Nevada and the valleys of the westernmost Basin and Range province. The Garlock Fault runs from a junction with the San Andreas Fault in the Antelope Valley, eastward to a junction with the Death Valley Fault Zone in the eastern Mojave Desert. It is named after the historic mining town of Garlock, founded in 1894 by Eugene Garlock and now a ghost town. Relatively few communities lie directly along the Garlock, as it is primarily situated in the desert, with Frazier Park, Tehachapi, ...
