Great Basin Desert in the context of "Wasatch Range"

The Mojave Desert (/moʊˈhɑːvi, mə-/ ; Mohave: Hayikwiir Mat'aar; Spanish: Desierto de Mojave) is a desert in the rain shadow of the southern Sierra Nevada mountains and Transverse Ranges in the Southwestern United States. Named after the indigenous Mohave people, it is located primarily in southeastern California and southwestern Nevada, with small portions extending into Arizona and Utah.

The Mojave Desert, together with the Sonoran, Chihuahuan, and Great Basin deserts, form a larger North American desert. Of these, the Mojave is the smallest and driest. It displays typical basin and range topography, generally having a pattern of a series of parallel mountain ranges and valleys. It is also the site of Death Valley, which is the lowest elevation in North America. The Mojave Desert is often colloquially called the "high desert", as most of it lies between 2,000 and 4,000 feet (610 and 1,220 m). It supports a diversity of flora and fauna.

Death Valley (Panamint: Tümpisa [tɨmbiʃa]) is a desert valley in Eastern California, United States, in the northern Mojave Desert, bordering the Great Basin Desert. It is thought to be the hottest place on Earth during summer.

Death Valley's Badwater Basin is the point of lowest elevation in North America, at 282 feet (86 m) below sea level. It is 84.6 miles (136.2 km) 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 hours of July 10, 1913, the United States Weather Bureau recorded a temperature of 134 °F (56.7 °C) at Furnace Creek in Death Valley, which stands as the highest ambient air temperature ever recorded on the surface of the Earth. However, this reading and several others taken in that period are disputed by some modern experts.

Death Valley National Park is a national park of the United States 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.

This list of North American deserts identifies areas of the continent that receive less than 10 in (250 mm) annual precipitation. The "North American Desert" is also the term for a large U.S. Level 1 ecoregion (EPA) of the North American Cordillera, in the Deserts and xeric shrublands biome (WWF). The continent's deserts are largely between the Rocky Mountains and Sierra Madre Oriental on the east, and the rain shadow–creating Cascades, Sierra Nevada, Transverse, and Peninsular Ranges on the west. The North American xeric region of over 95,751 sq mi (247,990 km) includes three major deserts, numerous smaller deserts, and large non-desert arid regions in the Western United States and in northeastern, central, and northwestern Mexico.

There are two species of kangaroo mouse (genus Microdipodops) native to the Great Basin Desert of the western United States, predominantly found in the state of Nevada. The name "kangaroo mouse" alludes to the species' extraordinary jumping ability, similar to the much larger-bodied kangaroos. The two species are:

• Dark kangaroo mouse – Microdipodops megacephalus
• Pale kangaroo mouse – Microdipodops pallidus

Both species of kangaroo mouse live in sandy desert ecosystems, and forage for seeds and vegetation amongst the scrub brush of their native habitat. The dark kangaroo mouse is also known to feed occasionally on insects and carrion. The mice rarely drinks water, instead deriving it metabolically from the foods it eats. The kangaroo mouse collects food and maintains large caches in their burrows, which are excavated to a length of between 3 and 8 ft (0.91 and 2.44 m). The burrow, the entrance to which the mouse covers during daylight hours, is also used to raise litters of between 2 and 7 young The pale kangaroo mouse burrows only in fine sand, while the dark kangaroo mouse prefers fine, gravelly soils but may also burrow in sand or sandy soil.

Owens Valley (Mono: Payahǖǖnadǖ, meaning "place of flowing water") is an arid valley of the Owens River in eastern California in the United States. It is located to the east of the Sierra Nevada, west of the White Mountains and Inyo Mountains, and is split between the Great Basin Desert and the Mojave Desert. The mountain peaks on its west side (including Mount Whitney) reach above 14,000 feet (4,300 m) in elevation, while the floor of the Owens Valley is at about 4,000 feet (1,200 m), making the valley the deepest in the United States. The Sierra Nevada casts the valley in a rain shadow, which makes Owens Valley "the Land of Little Rain". The bed of Owens Lake, now a predominantly dry endorheic alkali flat, sits on the southern end of the valley.

The current arid nature of the valley is mostly due to the Los Angeles Department of Water and Power diverting the water of the region. The valley provides water to the Los Angeles Aqueduct, the source of one-third of the water for city, and was the area at the center of one of the fiercest and longest-running episodes of the California Water Wars. Owens Lake was completely emptied by 1926, only 13 years after Los Angeles began diverting water. The water diversions inspired aspects of the 1974 film Chinatown.
