The Mojave Desert ( /
A rain shadow is a dry area on the leeward side of a mountainous area. The mountains block the passage of rain-producing weather systems and cast a "shadow" of dryness behind them. Wind and moist air is drawn by the prevailing winds towards the top of the mountains, where it condenses and precipitates before it crosses the top. The air, without much moisture left, advances across the mountains creating a drier side called the "rain shadow".
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to the processes of denudation. About one-third of the land surface of the world is arid or semi-arid. This includes much of the polar regions where little precipitation occurs and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location.
The Mojave Desert is bordered by the Great Basin Desert to its north 2,000 ft (610 m) in the Mojave are commonly referred to as the High Desert; however, Death Valley is the lowest elevation in North America at 280 ft (85 m) below sea level and is one of the Mojave Desert's most notorious places. Large parts of the Mojave Desert are often referred to as the "high desert", in contrast to the "low desert", the Sonoran Desert to the south. Most of the Mojave Desert is above 2,000 ft (610 m), with only Death Valley and the Colorado River basin in the east (including the neighbouring Las Vegas Valley) being lower. The Mojave Desert, however, is generally lower than the even higher Great Basin Desert to the north. The Mojave Desert occupies less than 50,000 sq mi (130,000 km2), making it the smallest of the North American deserts.and the Sonoran Desert to its south and east. Topographical boundaries include the Tehachapi Mountains to the west, and the San Gabriel Mountains and San Bernardino Mountains to the south. The mountain boundaries are distinct because they are outlined by the two largest faults in California – the San Andreas and Garlock faults. The Mojave Desert displays typical basin and range topography. Higher elevations above
The Great Basin Desert is part of the Great Basin between the Sierra Nevada and the Wasatch Range. The desert is a geographical region that largely overlaps the Great Basin shrub steppe defined by the World Wildlife Fund, and the Central Basin and Range ecoregion defined by the U.S. Environmental Protection Agency and United States Geological Survey. It is a temperate desert with hot, dry summers and snowy winters. The desert spans a large part of the state of Nevada, and extends into western Utah, eastern California, and Idaho. The desert is one of the four biologically defined deserts in North America, in addition to the Mojave, Sonoran, and Chihuahuan Deserts.
The Sonoran Desert is a North American desert which covers large parts of the Southwestern United States in Arizona and California and of Northwestern Mexico in Sonora, Baja California, and Baja California Sur. It is the hottest desert in Mexico. It has an area of 260,000 square kilometers (100,000 sq mi). The western portion of the United States–Mexico border passes through the Sonoran Desert.
The Tehachapi Mountains are a mountain range in the Transverse Ranges system of California in the Western United States. The range extends for approximately 40 miles (64 km) in southern Kern County and northwestern Los Angeles County.
The spelling Mojave originates from the Spanish language while the spelling Mohave comes from modern English. Both are used today, although the Mojave Tribal Nation officially uses the spelling Mojave; the word is a shortened form of Hamakhaave, their endonym in their native language, which means 'beside the water'.
Mohave or Mojave (Mojave: 'Aha Makhav) are a Native American people indigenous to the Colorado River in the Mojave Desert. The Fort Mojave Indian Reservation includes territory within the borders of California, Arizona, and Nevada. The Colorado River Indian Reservation includes parts of California and Arizona and is shared by members of the Chemehuevi, Hopi, and Navajo peoples.
An exonym or xenonym is an external name for a geographical place, a group of people, an individual person, or a language or dialect. It is a common name used only outside the place, group, or linguistic community in question. An endonym or autonym is an internal name for a geographical place, a group of people, or a language or dialect. It is a common name used only inside the place, group, or linguistic community in question; it is their name for themselves, their homeland, or their language.
The Mojave Desert receives less than 2 inches (51 mm) of rain a year and is generally between 2,000 and 5,000 feet (610 and 1,520 m) in elevation. The Mojave Desert also contains the Mojave National Preserve, as well as the lowest and hottest place in North America: Death Valley at 282 ft (86 m) below sea level, where the temperature often surpasses 120 °F (49 °C) from late June to early August. Zion National Park in Utah lies at the junction of the Mojave, the Great Basin Desert, and the Colorado Plateau. Despite its aridity, the Mojave (and particularly the Antelope Valley in its southwest) has long been a center of alfalfa production, fed by irrigation coming from groundwater and from the California Aqueduct.
Mojave National Preserve is a United States National Preserve located in the Mojave Desert of San Bernardino County, California, USA, between Interstate 15 and Interstate 40. The preserve was established October 31, 1994, with the passage of the California Desert Protection Act by the US Congress. Previously, it was the East Mojave National Scenic Area, under the jurisdiction of the Bureau of Land Management. Mojave National Preserve is vast. At 1,600,000 acres (650,000 ha), it is the third largest unit of the National Park System in the contiguous United States.
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, and the hottest, driest and lowest of all the national parks in the United States. The second-lowest point in the Western Hemisphere is in Badwater Basin, which is 282 feet (86 m) below sea level. Approximately 91% 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. Some examples include creosote bush, bighorn sheep, coyote, and the Death Valley pupfish, a survivor from much wetter times. UNESCO included Death Valley as the principal feature of its Mojave and Colorado Deserts Biosphere Reserve in 1984.
Zion National Park is an American national park located in southwestern Utah near the town of Springdale. A prominent feature of the 229-square-mile (590 km2) park is Zion Canyon, which is 15 miles (24 km) long and up to 2,640 ft (800 m) deep. The canyon walls are reddish and tan-colored Navajo Sandstone eroded by the North Fork of the Virgin River. The lowest point in the park is 3,666 ft (1,117 m) at Coalpits Wash and the highest peak is 8,726 ft (2,660 m) at Horse Ranch Mountain. Located at the junction of the Colorado Plateau, Great Basin, and Mojave Desert regions, the park has a unique geography and a variety of life zones that allow for unusual plant and animal diversity. Numerous plant species as well as 289 species of birds, 75 mammals, and 32 reptiles inhabit the park's four life zones: desert, riparian, woodland, and coniferous forest. Zion National Park includes mountains, canyons, buttes, mesas, monoliths, rivers, slot canyons, and natural arches.
The Mojave is a desert of temperature extremes and two distinct seasons. Winter months bring comfortable daytime temperatures, which occasionally drop to around 25 °F (−4 °C) on valley floors, and below 0 °F (−18 °C) at the highest elevations. Storms moving from the Pacific Northwest can bring rain and in some places even snow. More often, the rain shadow created by the Sierra Nevada as well as mountain ranges within the desert such as the Spring Mountains, bring only clouds and wind. In longer periods between storm systems, winter temperatures in valleys can approach 80 °F (27 °C).
The Pacific Northwest (PNW), sometimes referred to as Cascadia, is a geographic region in western North America bounded by the Pacific Ocean to the west and (loosely) by the Cascade Mountain Range on the east. Though no official boundary exists, the most common conception includes the Canadian province of British Columbia (BC) and the U.S. states of Idaho, Oregon, and Washington. Broader conceptions reach north into Southeast Alaska and Yukon, south into northern California, and east to the Continental Divide to include Western Montana and parts of Wyoming. Narrower conceptions may be limited to the coastal areas west of the Cascade and Coast mountains. The variety of definitions can be attributed to partially overlapping commonalities of the region's history, culture, geography, society, and other factors.
The Sierra Nevada is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada. The Sierra Nevada is part of the American Cordillera, a chain of mountain ranges that consists of an almost continuous sequence of such ranges that form the western "backbone" of North America, Central America, South America and Antarctica.
The Spring Mountains are a mountain range of Southern Nevada in the United States, running generally northwest-southeast along the west side of Las Vegas and south to the border with California. Most land in the mountains is owned by the United States Forest Service and the Bureau of Land Management and managed as the Spring Mountains National Recreation Area within the Humboldt-Toiyabe National Forest and the Red Rock Canyon National Conservation Area.
Spring weather continues to be influenced by Pacific storms, but rainfall is more widespread and occurs less often after April. By early June, it is rare for another Pacific storm to have a significant impact on the region's weather; and temperatures after the middle of May are normally above 90 °F (32 °C) and frequently above 100 °F (38 °C).
Summer weather is dominated by heat. Temperatures on valley floors can soar above 120 °F (49 °C) and above 130 °F (54 °C) at the lowest elevations. Low humidity, high temperatures, and low pressure, draw in moisture from the Gulf of Mexico creating thunderstorms across the desert southwest known as the North American monsoon. While the Mojave does not get nearly the amount of rainfall the Sonoran desert to the south receives, monsoonal moisture will create thunderstorms as far west as California's Central Valley from mid-June through early September.
The Gulf of Mexico is an ocean basin and a marginal sea of the Atlantic Ocean, largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States, on the southwest and south by Mexico, and on the southeast by Cuba. The U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida border the Gulf on the north, which are often referred to as the "Third Coast", in comparison with the U.S. Atlantic and Pacific coasts.
The North American monsoon, variously known as the Southwest monsoon, the Mexican monsoon, the New Mexican monsoon, or the Arizona monsoon, is a pattern of pronounced increase in thunderstorms and rainfall over large areas of the southwestern United States and northwestern Mexico, typically occurring between July and mid September. During the monsoon, thunderstorms are fueled by daytime heating and build up during the late afternoon-early evening. Typically, these storms dissipate by late night, and the next day starts out fair, with the cycle repeating daily. The monsoon typically loses its energy by mid-September when drier and cooler conditions are reestablished over the region. Geographically, the North American monsoon precipitation region is centered over the Sierra Madre Occidental in the Mexican states of Sinaloa, Durango, Sonora and Chihuahua.
The Central Valley is a flat valley that dominates the geographical center of the U.S. state of California. It is 40 to 60 miles wide and stretches approximately 450 miles (720 km) from north-northwest to south-southeast, inland from and parallel to the Pacific Ocean coast. It covers approximately 18,000 square miles (47,000 km2), about 11% of California's total land area. The valley is bounded by the Sierra Nevada to the east and the Coast Ranges to the west.
Autumn is generally pleasant, with one to two Pacific storm systems creating regional rain events. October is one of the driest and sunniest months in the Mojave; and average high temperatures usually remain between 70 °F (21 °C) and 90 °F (32 °C) on the valley floors.
After temperature, wind is the most significant weather phenomenon in the Mojave. Across the region windy days are common; and also common in areas near the transition between the Mojave and the California low valleys, including near Cajon Pass, Soledad Canyon and the Tehachapi areas. During the June Gloom, cooler air can be pushed into the desert from Southern California. In Santa Ana wind events, hot air from the desert blows into the Los Angeles basin and other coastal areas. Wind farms in these areas generate power from these winds.
The other major weather factor in the region is elevation. The highest peak within the Mojave is Charleston Peak at 11,918 feet (3,633 m), while the Badwater Basin in Death Valley is 279 feet (85 m) below sea level. Accordingly, temperature and precipitation ranges wildly in all seasons across the region.
The Mojave Desert has not historically supported a fire regime because of low fuel loads and connectivity. However, in the last few decades, invasive annual plants such as some within the genera Bromus , Schismus and Brassica have facilitated fire. This has significantly altered many areas of the desert.At higher elevations, fire regimes are regular but infrequent.

The Mojave Desert is defined by numerous mountain ranges creating its xeric conditions. These ranges often create valleys, endorheic basins, salt pans, and seasonal saline lakes when precipitation is high enough. These mountain ranges and valleys are part of the Basin and Range Province and the Great Basin, a geologic area of crustal thinning which pulls open valleys over millions of years. Most of the valleys are internally drained (endorheic basins), so all precipitation that falls within the valley does not eventually flow to the ocean. Some of the Mojave (toward the east, in and around the Colorado River/Virgin River Gorge) is within a different geographic domain called the Colorado Plateau.
While the Mojave Desert itself is sparsely populated, it has increasingly become urbanized in recent years. The metropolitan areas include Las Vegas, the largest city in the Mojave with a metropolitan population of around 2.3 million in 2015; St. George is the northeastern-most metropolitan area in the Mojave, and is located at the convergence of the Mojave, Great Basin and Colorado Plateau. Lancaster is the largest California city in the desert; over 850,000 people live in areas of the Mojave attached to the Greater Los Angeles metropolitan area, including Palmdale and Lancaster, (referred to as the Antelope Valley), Victorville, Apple Valley and Hesperia (referred to as the Victor Valley) attached to the Inland Empire metropolitan area, the 14th largest in the nation.
Smaller cities or micropolitan areas in the Mojave Desert include Helendale, Lake Havasu City, Kingman, Laughlin, Bullhead City and Pahrump. All have experienced rapid population growth since 1990.
Notable towns with fewer than 30,000 people in the Mojave include Barstow, Boron, California City, Helendale, Joshua Tree, Landers, Lone Pine, Lucerne Valley, Mojave, Needles, Nipton, Pioneertown, Randsburg, Ridgecrest, Rosamond, Yucca Valley and Twentynine Palms in California; Mesquite and Moapa Valley in Nevada; and Hurricane in Utah.
The California portion of the desert also contains Edwards Air Force Base and Naval Air Weapons Station China Lake, noted for experimental aviation and weapons projects, and the largest Marine Corps base in the world at Twentynine Palms. The US Army also maintains Fort Irwin & the National Training Center (NTC) which is another major training area for the United States military. Mojave airport is also home to a long term storage facility for large airplanes due to extremely dry non-corrosive weather conditions and a hard ground ideal for parking aircraft. The airport also houses the Air and Space Port and was one of the test centres for the Virgin Galactic Fleet.
The Mojave Desert has several ghost towns; the most significant are the gold-mining town of Oatman, Arizona, the silver-mining town of Calico, California, and the old railroad depot of Kelso. Some of the other ghost towns are more modern, created when U.S. Route 66 (and the lesser-known U.S. Route 91) were abandoned in favor of the Interstates. The Mojave Desert is crossed by major highways Interstate 15, Interstate 40, U.S. Route 95, U.S. Route 395 and California State Route 58.
Other than the Colorado River on the eastern half of the Mojave, few long streams cross the desert. The Mojave River is an important source of water for the southern parts of the desert. The Amargosa River flows from the Great Basin Desert south to near Beatty, Nevada, then underground through Ash Meadows before returning to the surface near Shoshone, California, disappearing underground again a short while later and has its final outlet into the southern end of Death Valley. The riverbed passes under SR 127 near Dumont Dunes before turning north into Death Valley National Park.
The Mojave Desert is also home to the Devils Playground, about 40 miles (64 km) of dunes and salt flats going in a northwest-southeasterly direction. The Devils Playground is a part of the Mojave National Preserve and is between the town of Baker, California and Providence Mountains. The Cronese Mountains are within the Devils Playground.
The Mojave Desert is one of the most popular tourism spots in North America, primarily because of the gambling destination of Las Vegas. The Mojave is also known for its scenic beauty, playing host to Death Valley National Park, Joshua Tree National Park, and the Mojave National Preserve. Lakes Mead, Mohave, and Havasu provide water sports recreation, and vast off-road areas entice off-road enthusiasts. The Mojave Desert also includes two California State Parks, the Antelope Valley California Poppy Reserve, in Lancaster, and Saddleback Butte State Park, in Hi Vista. Hoover Dam is a popular tourist destination. Visitors get a chance to see the structure, the hydroelectric power plant, and hear the history of the dam's construction during the Great Depression.
Besides the major national parks, there are other areas of identified significance and tourist interest in the desert such as the Big Morongo Canyon Preserve, within the Colorado Desert, and the Red Rock Canyon National Conservation Area, 17 miles (27 km) west of Las Vegas, both of which are managed by the Bureau of Land Management.
Among the more popular and unique tourist attractions in the Mojave is the self described world's tallest thermometer at 134 feet (41 m) high, which is along Interstate 15 in Baker, California. The newly renovated Kelso Depot is the Visitor Center for the Mojave National Preserve. Nearby the massive Kelso Dunes are a popular recreation spot. Nipton, California, on the northern entrance to the Mojave National Preserve, is a restored ghost town founded in 1885.
Several attractions and natural features are in the Calico Mountains. Calico Ghost Town, in Yermo, is administered by San Bernardino County. The ghost town has several shops and attractions, and inspired Walter Knott to build Knott's Berry Farm. The BLM also administers Rainbow Basin and Owl Canyon, two "off-the-beaten-path" scenic attractions together north of Barstow in the Calicos. The Calico Early Man Site, in the Calico Hills east of Yermo, is believed by some archaeologists, including the late Louis Leakey, to show the earliest evidence with lithic stone tools found here of human activity in North America. The Calico Peaks scenically rise above all the destinations.
A tour of the Mojave Desert inspired American songwriter Carrie Jacobs-Bond to compose the parlor song "A Perfect Day" in 1909.
The flora of the Mojave Desert help define what is called the Mojave Desert in that the desert itself is generally considered to be outlined by the extent of growth of one of its plants, the Joshua tree ( Yucca brevifolia ). Mojave Desert flora is not a vegetation type, although plants in the area have evolved in isolation because of physical barriers. This area includes southeastern California and smaller parts of central California, southern Nevada, southwestern Utah and northwestern Arizona in the United States. The flora are adapted to extremely hot and dry conditions, but generally not as extreme as the adaptations needed for survival in the flora of the Sonoran Desert, which has an overlap in its major flora, such as the creosote bush ( Larrea tridentata ).
The soil types in the Mojave and Sonoran deserts are mostly derived from volcano, specifically the areas in California. As the topography goes down, particle sizes decreases as you move down the gradient, where you can also find low alkalinity. These erosional gradient is a habitat for many plant communities. As you go up the gradient of the desert, you will find more pediment and alluvial fan soil. In this areas, the flora is mostly succulents. As you move down the gradient, this area is described to be the upper and lower bajada, then you move into playa and salina, and finally you will reach the river. Drought deciduous plants are found in the alluvial fans and upper bajada. Evergreen perennials are found in some parts of the upper bajada, but it is mostly found in lower bajada. Once the salinity increases, you will find more salt-tolerant plants. In the river areas, deep-rooted plants reside. Due to the harsh and dry conditions in the desert, the plants have adapted to have succulent leaves, with CAM photosynthesis, spines, buried bulbs, hairy or waxy leaves, photosynthetic stems, deep tap roots, and ephemerals.
The U.S. Bureau of Land Management (BLM) manages public lands in the Mojave Desert as part of its "crown jewels of the American West" National Landscape Conservation System. It has designated numerous large off-road vehicle open use areas on public lands in the western Mojave Desert, including El Mirage, Jawbone Canyon, Rasor, Spangler Hills, Stoddard Valley, Dove Spring Canyon, Dumont Dunes, and the world's largest open off-road vehicle use area, Johnson Valley. Open areas designated for unrestricted vehicle travel in the western Mojave Desert total 363,480 acres (1,471.0 km2). Several additional open areas dedicated to unrestricted vehicle travel on public lands have been designated in the northern and eastern Colorado (NECO) Desert. In 2002, BLM designated all washes in the southeastern third of the NECO planning area as also open to unrestricted vehicle travel. This was followed in 2003 by BLM expanding the off-road vehicle network in the western Mojave Desert to enhance off-road vehicle recreation opportunity. In 2004, relative to the case of Center for Biological Diversity, et al., Plaintiffs, v. Bureau of Land Management, et al., Defendants; the United States District court enjoined "all off-road vehicle use in the washes of the NECO Desert planning area pending issuance of a new biological opinion.". :a A new biological opinion was subsequently issued and BLM's open wash designation in the NECO planning area was reinstated. In 2006, several environmental groups protested an additional route network expansion designated under the West Mojave Desert (WEMO) plan.
In 2009, U.S. District Judge Susan Illston ruled against the BLM's proposed designation of additional off-road vehicle use allowance in the western Mojave Desert. According to the ruling, the BLM violated its own regulations 5,000 miles (8,000 km) of off-roading routes in 2006. According to Judge Ilston, the BLM's designation was significantly "flawed because it does not contain a reasonable range of alternatives" to limit damage to sensitive habitat. Judge Illston found the bureau had inadequately analyzed the routes' impacts on air quality, soils, plant communities, riparian habitats, and sensitive species such as the endangered Mojave fringe-toed lizard, pointing out that the desert and its resources are "extremely fragile, easily scarred, and slowly healed."when it designated approximately
The court also found the BLM failed to follow route designation procedures established in the agency's own California Desert Conservation Area Plan, which allowed visitors to create hundreds of illegal OHV routes during the past three decades. The plan normally requires the BLM to consider the impacts to private property, non-motorized recreation opportunity, and natural resources before establishing off-road areas.The adopted West Mojave plan amendment was found to have violated the BLM's own manual of regulations, the Federal Land Policy and Management Act of 1976 (FLPMA) and the National Environmental Policy Act of 1969 (NEPA). The ruling was considered a success for a coalition of conservation groups, including the California Native Plant Society, Friends of Juniper Flats, the Alliance for Responsible Recreation, Community Off-Road Vehicle Watch, The Center for Biological Diversity, Sierra Club, and The Wilderness Society, who together initiated the legal challenge in late 2006.
In 2011, Judge Illston ruled on a remedy request submitted by the ten involved environmental organizations. BLM in this ruling was directed to complete a revised WEMO route designation complying with all laws and regulations by March 2014. The agency is also required per this ruling to place signs on all off-road vehicle routes which are legal to use, create a monitoring plan to determine if illegal vehicle use is occurring, and provide additional enforcement to prevent illegal use.
The Red Rock Canyon National Conservation Area in Clark County, Nevada, is an area managed by the Bureau of Land Management as part of its National Landscape Conservation System, and protected as a National Conservation Area. It is about 15 miles (24 km) west of Las Vegas, and is easily seen from the Las Vegas Strip. More than two million people visit the area each year.
The Mojave River is an intermittent river in the eastern San Bernardino Mountains and the Mojave Desert in San Bernardino County, California, United States. Most of its flow is underground, while its surface channels remain dry most of the time, with the exception of the headwaters and several bedrock gorges in the lower reaches.
Lake Mead National Recreation Area is a U.S. National Recreation Area located in southeastern Nevada and northwestern Arizona. Operated by the National Park Service, Lake Mead NRA follows the Colorado River corridor from the westernmost boundary of Grand Canyon National Park to just north of the cities of Laughlin, Nevada and Bullhead City, Arizona. It includes all of the eponymous Lake Mead as well as the smaller Lake Mohave – reservoirs on the river created by Hoover Dam and Davis Dam, respectively – and the surrounding desert terrain and wilderness.
Kelso Dunes, also known as the Kelso Dune Field, is the largest field of aeolian sand deposits in the Mojave Desert. The region is protected by the Mojave National Preserve and is located near the town of Baker, San Bernardino County, California, and the Preserve Visitor Center. The dune field covers 45 square miles (120 km2) and includes migrating dunes, vegetation-stabilized dunes, sand sheets, and sand ramps. The tallest dunes rise up to 650 feet (200 m) above the surrounding terrain.
The Chuckwalla Mountains are a mountain range in the transition zone between the Colorado Desert—Sonoran Desert and the Mojave Desert, climatically and vegetationally, in Riverside County of southern California.
The Providence Mountains are found in the eastern Mojave Desert of San Bernardino County, California, U.S. The range reaches an elevation of 7,162 feet (2,183 m) at Edgar Peak and is home to the Mitchell Caverns Natural Preserve in the Providence Mountains State Recreation Area, and the Mojave National Preserve.
The Lower Colorado River Valley ("LCRV") is the river region of the lower Colorado River of the southwestern United States in North America that rises in the Rocky Mountains and has its outlet at the Colorado River Delta in the northern Gulf of California in northwestern Mexico, between the states of Baja California and Sonora. This north–south stretch of the Colorado River forms the border between the U.S. states of California/Arizona and Nevada/Arizona, and between the Mexican states of Baja California/Sonora.
The Kiavah Wilderness is a federally designated wilderness area located in the Mojave Desert, Scodie Mountains, and Southern Sierra Nevada Mountains in Kern County, California, United States. California State Route 178 connects the town of Lake Isabella, California to state Highway 14 in the east, crossing Walker Pass at the north boundary of the wilderness.
Rasor Off-Highway Vehicle Area is a remote public use area for the off-highway vehicle user located in the Mojave Desert about 50 miles (80 km) east of Barstow, California, administered by the Bureau of Land Management.
The Piper Mountain Wilderness is a federally designated wilderness area located in the White Mountains 20 miles (32 km) northeast of Big Pine, California in Inyo County, California.
Dumont Dunes is an area of the Mojave Desert containing large sand dunes, located approximately 31 miles north of Baker, California on California State Route 127. Bordered by steep volcanic hills and the slow running Amargosa River, the region is easily recognized from a distance by its distinctive sand dunes. The elevation here varies from 700 feet, at the river, to 1200 feet at the top of Competition Hill, the tallest of the dunes.
The Sylvania Mountains Wilderness is a federally designated wilderness area located 30 miles (48 km) east of Bishop in the state of California. The wilderness is 18,677acres in size and is managed by the Bureau of Land Management (BLM). The California Desert Protection Act of 1994 created the Sylvania Mountains Wilderness and was added to the National Wilderness Preservation System. The wilderness is bordered by Nevada stateline on the east, Piper Mountain Wilderness on the west and Death Valley National Park to the south.
The Deserts of California have unique ecosystems and habitats, a sociocultural and historical "Old West" collection of legends, districts, and communities, and they also form a popular tourism region of dramatic natural features and recreational development. All of the deserts are located in eastern Southern California, in the Western United States.
The Sacramento Wash is a major drainage of northwest Arizona in Mohave County. The wash is east of the Black Canyon of the Colorado and drains into the south-flowing Colorado River 45 mi south of Lake Mohave, and 90 mi south of Hoover Dam at Lake Mead. The wash outfall is in the center-south of the Havasu-Mohave Lakes Watershed. An equivalent wash drains to the west of the Colorado River and the Black Canyon, draining southeast Nevada and a small part of California, the Piute Wash of the Piute Valley. The Piute Wash outfall is upstream of the Sacramento's outfall by about 15 miles.
The Clipper Mountain Wilderness is a wilderness area in the Clipper Mountains of the eastern Mojave Desert and within Mojave Trails National Monument, located in northeastern San Bernardino County, California. It is under the jurisdiction of the Bureau of Land Management.
Sand to Snow National Monument is a U.S. National Monument located in San Bernardino County and into northern Riverside County, Southern California.
