The Mojave Desert, together with the [[Sonoran Desert|Sonoran]], [[Chihuahuan Desert|Chihuahuan]], and [[Great Basin Desert|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 {{convert|2,000|and|4,000|ft|m|-1}}. It supports a diversity of flora and fauna.
The Mojave Desert is bordered by the [[Great Basin Desert]] to its north<ref name=MDW>''Mojave Desert Wildflowers'', Pam MacKay, 2nd Ed. 2013, p. 1</ref> and the [[Sonoran Desert]] to its south and east.<ref name=MDW/> Topographical boundaries include the [[Tehachapi Mountains]] and the [[Sierra Pelona Ridge]] to the west, the [[Sierra Nevada (U.S.)|Sierra Nevada]] and the [[Inyo Mountains]] to the northwest, 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 Fault|San Andreas]] and [[Garlock Fault|Garlock]] faults. The Mojave Desert displays typical [[basin and range]] topography. Higher elevations above {{convert|2000|ft|abbr=on}} in the Mojave are commonly referred to as the High Desert; however, [[Death Valley]] is the lowest elevation in North America at {{convert|280|ft|abbr=on}} below sea level and is one of the Mojave Desert's harshest climates and best-known 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 {{convert|2000|ft|abbr=on}}, with only Death Valley and the Colorado River basin in the east (including the neighboring 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&nbsp;km<sup>2</sup>), making it the smallest of the North American deserts.<ref name=MDW/>


The {{cvt|54,000|sqmi|km2}} desert supports a number of human activities, including recreation, ranching, and military training.<ref name=":2"/> The Mojave Desert also contains various [[silver]], [[tungsten]], [[iron]] and [[gold]] deposits.<ref name=Dibblee/>{{rp|124}}
The spelling ''Mojave'' originates from the Spanish language while the spelling ''Mohave'' comes from modern English. Both are used today, although the [[Mohave people|Mojave]] Tribal Nation officially uses the spelling ''Mojave''; the word is a shortened form of '''{{lang|mov|Hamakhaave}}''', their [[exonym and endonym|endonym]] in their native language, which means "beside the water".<ref>{{cite web |title=American Indian History |url=http://www.bigorrin.org/mojave_kids.htm}}</ref>

==Climate==
The Mojave Desert is generally between {{convert|2000|and|5000|ft}} in elevation. The Mojave Desert also contains the [[Mojave National Preserve]], as well as the lowest and hottest place in North America: [[Death Valley National Park|Death Valley]] at {{convert|282|ft|abbr=on}} below sea level, where the temperature often surpasses {{convert|120|F|C|abbr=on}} from late June to early August. The driest parts of the Mojave Desert receive less than {{convert|2|in|mm|-1|disp=or}} of precipitation per year – the lowest in North America – whilst the desert’s edges receive about {{convert|9|in|mm|-1|disp=or}}.


==Geography==
[[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]].
[[File:Joshua Tree NP - Joshua Tree 2.jpg|thumb|upright|The Joshua tree (''[[Yucca brevifolia]]'') is [[endemism|endemic]] and exclusive to the Mojave Desert.<ref>{{cite web |title=Mojave Desert Biome |url=https://www.blueplanetbiomes.org/mojave_desert.php#:~:text=The%20Mojave%20Desert%20lies%20in,cold%20air%20in%20the%20mountains. |access-date=July 23, 2021 |website=Blue Planet Biomes}}</ref>]]
[[File:Mustard Blue Sunset.jpg|thumb|left|upright|Mustard blue summer sunset at [[Landers, California]]]]
The Mojave Desert is a desert bordered to the west by the Sierra Nevada mountain range and the [[California montane chaparral and woodlands]], and to the south and east by the Sonoran Desert. The boundaries to the east of the Mojave Desert are less distinctive than the other boundaries because there is no presence of an indicator species, such as the [[Yucca brevifolia|Joshua tree]] (''Yucca brevifolia''),<ref name=":3">{{cite book|last1=Rundel|first1=Philip W|first2=Arthur C|last2=Gibson|title=Ecological communities and processes in a Mojave Desert ecosystem|publisher=Cambridge University Press|year=2005}}</ref> which is endemic to the Mojave Desert. The Mojave Desert is distinguished from the Sonoran Desert and other deserts adjacent to it by its warm temperate climate, as well as [[flora and fauna]] such as [[Olneya|ironwood]] (''Olneya'' ''tesota''), [[Parkinsonia florida|blue Palo Verde]] (''Parkinsonia florida''), [[Justicia californica|chuparosa]] (''Justicia californica''), [[Menodora spinescens|spiny menodora]] (''Menodora spinescens''), [[desert senna]] (''Cassia armata''), [[Psorothamnus arborescens|California dalea]] (''Psorothamnus arborescens''), [[Washingtonia filifera|California fan palm]] (Washingtonia filifera) and [[Acamptopappus|goldenhead]] (''Acamptopappus shockleyi''). Along with these other factors, these plants differentiate the Mojave from the nearby Sonoran Desert.<ref name=":0" />


The Mojave Desert is bordered by the [[San Andreas Fault|San Andreas]] fault to the southwest and the [[Garlock Fault|Garlock]] fault to the north. The mountains elevated along the length of the San Andreas fault provide a clear border between the Mojave Desert and the coastal regions to the west.<ref name=Dibblee /> The Garlock fault separates the Mojave Desert from the Sierra Nevada and [[Tehachapi Mountains|Tehachapi]] mountains, which provide a natural border to the Mojave Desert. There are also abundant [[alluvial fan]]s, which are called [[Bajada (geography)|bajadas]], that form around the mountains within the Mojave Desert and extend down toward the low altitude basins,<ref name=":3" /> which contain dried lake beds called playas, where water generally collects and evaporates, leaving large volumes of salt. These playas include [[Rogers Dry Lake]], and [[Naval Air Weapons Station China Lake|China Lake]]. Dry lakes are a noted feature of the Mojave landscape.<ref name=":0" /> The Mojave Desert is also home to the [[Devils Playground]], about {{convert|40|mi|km}} of dunes and salt flats going in a northwest-southeasterly direction. The Devil's 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 Devil's Playground.
The Mojave is a desert of temperature extremes and two distinct seasons. Winter months bring comfortable daytime temperatures, which occasionally drop to around {{convert|25|F|C|abbr=on}} on valley floors, and below {{convert|0|F|C|abbr=on}} 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 (U.S.)|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 {{convert|80|F|C|abbr=on}}.


There are very few surface [[river]]s in the Mojave Desert, but two major rivers generally flow underground. One is the intermittent [[Mojave River]], which begins in the San Bernardino mountains and disappears underground in the Mojave Desert.<ref>{{cite web|url=https://www.westernrivers.org/discover/river-of-the-month/mojave-river|title=Mojave River|publisher=Western Rivers Conservancy|date=February 2020}}</ref> The other is the [[Amargosa River]], which flows partly underground through the Mojave Desert along a southward path.<ref>{{cite magazine|url=https://www.nationalgeographic.com/environment/article/life-on-the-amargosaa-desert-river-faced-with-drought|archive-url=https://web.archive.org/web/20210611163844/https://www.nationalgeographic.com/environment/article/life-on-the-amargosaa-desert-river-faced-with-drought|url-status=dead|archive-date=June 11, 2021|title=Life on the Amargosa—a desert river faced with drought|magazine=National Geographic|first=Stefan|last=Lovgren|date=June 11, 2021}}</ref> The Manix, Mojave, and the Little Mojave lakes are all large but shallow.<ref name=":3"/>{{rp|7}} [[Soda Lake (San Bernardino County)|Soda Lake]] is the principal saline basin of the Mojave Desert. [[Spring (hydrology)|Natural springs]] are typically rare throughout the Mojave Desert,<ref name=":3"/>{{rp|19}} but there are two notable springs, [[Ash Meadows National Wildlife Refuge|Ash Meadows]] and [[Oasis Valley]]. Ash Meadows is formed from several other springs, which all draw from deep underground. Oasis Valley draws from the nearby Amargosa River.
Spring weather continues to be influenced by Pacific storms, but rainfall is less 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 {{convert|90|F|C|abbr=on}} and frequently above {{convert|100|F|C|abbr=on}}.


=== Climate ===
Summer weather is dominated by heat. Temperatures on valley floors can soar above {{convert|120|F|C|abbr=on}} and above {{convert|130|F|C|abbr=on}} 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|North American monsoon]]. While the Mojave does not get nearly the amount of monsoonal rainfall the [[Sonoran desert]] to the south receives, this monsoon can create thunderstorms as far west as California's [[Central Valley (California)|Central Valley]] from mid-June through early September.
Extremes in temperatures throughout the seasons characterize the climate of the Mojave Desert. Freezing temperatures as well as strong winds are not uncommon in the winter, as well as precipitation such as rain and snow in the mountains. In contrast, temperatures above {{Convert|100|F}} are not uncommon during the summer months.<ref>{{Cite web|title=Weather - Mojave National Park Reserve|url=https://www.nps.gov/moja/planyourvisit/weather.htm|website=National Park Service}}</ref> There is an annual average precipitation of {{Convert|2 to 6|in|sp=us}}, although regions at high altitudes such as the portion of the Mojave Desert in the [[San Gabriel Mountains|San Gabriel mountains]] may receive more rain.<ref name=Dibblee /><ref name=":1" /> Most of the precipitation in the Mojave comes from the Pacific Cyclonic storms that are generally present passing eastward in November to April.<ref name=Dibblee/> Such storms generally bring rain and snow only in the mountainous regions, as a result of the effect of the mountains, which [[Rain shadow|creates a drying effect on its leeward slopes]].<ref name=Dibblee />
[[File:Desert Diablo.jpg|thumb|right|Clouds reflecting high wind conditions from [[orographic lift]] in the Mojave Desert]]


During the late summer months, there is also the possibility of strong thunderstorms, which bring heavy showers or cloudbursts. These storms can result in [[Flash flood|flash flooding]].<ref>{{cite web|title=Precipitation History of the Mojave Desert Region, 1893–2001|first1=Richard|last1=Hereford|first2=Robert H|last2=Webb|first3=Claire I|last3=Longpre|url=https://pubs.usgs.gov/fs/fs117-03/|publisher=USGS|id=Fact Sheet 117-03|year=2004}}</ref>
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 {{convert|70|F|C|abbr=on}} and {{convert|90|F|C|abbr=on}} on the valley floors.


[[File:Desert_Electric.jpg|thumb|left|A powerful High Desert [[summer]] storm sweeps rapidly across the Mojave Desert.]]
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, California|Tehachapi]] areas. During the [[June Gloom]], cooler air can be pushed into the desert from Southern California. In [[Santa Ana wind]] events, hot and very dry air from the desert blows into the [[Los Angeles basin]] and other coastal areas. [[Wind farm]]s in these areas generate power from these winds.


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 fires by serving as a fuel bed. This has significantly altered many areas of the desert. At higher elevations, fire regimes are regular but infrequent.<ref>{{cite journal|last1=Brooks|first1=Matthew L|first2=JR|last2=Matchett|title=Spatial and temporal patterns of wildfires in the Mojave Desert, 1980–2004|journal=Journal of Arid Environments|volume=67|year=2006|pages=148–164|doi=10.1016/j.jaridenv.2006.09.027|bibcode=2006JArEn..67..148B}}</ref>
The other major weather factor in the region is elevation. The highest peak within the Mojave is [[Charleston Peak]] at {{convert|11918|ft}},<ref name="State of Nevada"/> while the [[Badwater Basin]] in Death Valley is {{convert|279|ft}} below sea level.<ref name=NED>{{cite web|url=https://catalog.data.gov/dataset/usgs-national-elevation-dataset-ned-1-meter-downloadable-data-collection-from-the-national-map-|title=USGS National Elevation Dataset (NED) 1 meter Downloadable Data Collection from The National Map 3D Elevation Program (3DEP) – National Geospatial Data Asset (NGDA) National Elevation Data Set (NED)|publisher=[[United States Geological Survey]]|date=September 21, 2015|access-date=September 22, 2015}}</ref> Accordingly, temperature and precipitation ranges wildly in all seasons across the region.

{{category see also|Mountain ranges of the Mojave Desert|Valleys of the Mojave Desert|Lakes of the Mojave Desert}}
The Mojave Desert is defined by numerous [[mountain range]]s creating its xeric conditions. These ranges often create valleys, [[endorheic basin]]s, [[salt pan (geology)|salt pans]], and seasonal [[saline lake]]s 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, Nevada|Las Vegas]], the largest city in the Mojave with a metropolitan population of around 2.3 million in 2015; [[St. George, Utah|St. George]] is the northeasternmost metropolitan area in the Mojave, with a population of around 200,000 in 2020, and is located at the convergence of the Mojave, Great Basin and Colorado Plateau. [[Lancaster, California|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 area|Greater Los Angeles]] metropolitan area, including Palmdale and Lancaster (referred to as the Antelope Valley), [[Victorville, California|Victorville]], [[Apple Valley, California|Apple Valley]] and [[Hesperia, California|Hesperia]] (referred to as the [[Victor Valley, California|Victor Valley]]) attached to the [[Inland Empire (CA)|Inland Empire]] metropolitan area, the 14th largest in the nation.

The Los Angeles exurban area of [[Lancaster, California|Lancaster]]-[[Palmdale, California|Palmdale]] has more than 400,000 residents, and the [[Victorville, California|Victorville]] area to its east has more than 300,000 residents.<ref name=":1" /> Smaller cities or [[micropolitan]] areas in the Mojave Desert include [[Helendale, California|Helendale]], [[Lake Havasu City, Arizona|Lake Havasu City]], [[Kingman, Arizona|Kingman]], [[Laughlin, Nevada|Laughlin]], [[Bullhead City, Arizona|Bullhead City]] and [[Pahrump, Nevada|Pahrump]]. All have experienced rapid population growth since 1990. 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.


The Mojave Desert has several [[ghost town]]s. The most significant are the silver and copper-mining town of [[Calico, San Bernardino County, California|Calico, California]], and the old railroad depot of [[Kelso, California]]. 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 construction of [[Interstate highway|Interstates]]. [[California State Route 14|CA SR 14]], [[Interstate 15]], [[Interstate 40]], [[California State Route 58|CA SR 58]], [[California State Route 138|CA SR 138]], [[US Route 95]], and [[US Route 395]] are the main highways that traverse the Mojave Desert.

The Mojave Desert is a source of various minerals and metallic materials. Due to the climate, there is an accumulation of weathered bedrock, fine sand and silt, both sand and silt sediments becoming converted into [[colluvium]].<ref>{{Cite journal |last1=Persico |first1=L.P. |last2=McFadden |first2=L.D. |last3=McAuliffe |first3=J.R. |last4=Rittenour |first4=T.M. |last5=Stahlecker |first5=T.E. |last6=Dunn |first6=S.B. |last7=Brody |first7=S.A.T. |date=2021-09-30 |title=Late Quaternary geochronologic record of soil formation and erosion: Effects of climate change on Mojave Desert hillslopes (Nevada, USA) |url=https://doi.org/10.1130/G49270.1 |journal=Geology |volume=50 |issue=1 |pages=54–59 |doi=10.1130/G49270.1 |s2cid=244264071 |issn=0091-7613}}</ref> The deposits of gold, tungsten, and silver have been mined frequently prior to the [[World War II|Second World War]].<ref name=Dibblee/>{{rp|124}} Additionally, there have been deposits of [[copper]], [[tin]], [[Lead zirconate titanate|lead-zinc]], [[manganese]], [[iron]], and various [[Radioactive decay|radioactive substances]] but they have not been mined for [[Economy|commercial]] use.<ref name=Dibblee />{{rp|124}}
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 [[Marine Corps Air Ground Combat Center Twentynine Palms|largest Marine Corps base]] in the world at Twentynine Palms. The US Army also maintains [[Fort Irwin National Training Center#Geography|Fort Irwin]] & the National Training Center (NTC) which is another major training area for the United States military. [[Mojave Air and Space Port|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 centers for the Virgin Galactic Fleet.


==Ecology==
The Mojave Desert has several [[ghost town]]s; the most significant are the gold-mining town of [[Oatman, Arizona]], the silver/copper-mining town of [[Calico, San Bernardino County, California|Calico, California]], and the old railroad depot of [[Kelso, California|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 [[Interstate highway|Interstates]]. The Mojave Desert is crossed by major highways [[Interstate 15]], [[Interstate 40]], [[U.S. Route 95]], [[U.S. Route 395]], [[California State Route 58]], [[California State Route 14]], [[California State Route 138]] and [[California State Route 18]]


===Flora===
Other than the [[Colorado River (U.S.)|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 flora of the Mojave Desert consists of various [[Endemism|endemic]] plant species, notably the [[Yucca brevifolia|Joshua Tree]], which is a notable endemic and [[indicator species]] of the desert. There is more endemic flora in the Mojave Desert than almost anywhere in the world.<ref name=":0" /> Mojave Desert flora is not a [[vegetation type]], although the plants in the area have evolved in isolation because of the physical barriers of the Sierra Nevadas and the Colorado Plateau.

The Mojave Desert is also home to the [[Devils Playground]], about {{convert|40|mi|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 [[Lake Mead|Mead]], [[Lake Mohave|Mohave]], and [[Lake Havasu|Havasu]] provide water sports recreation, and vast off-road areas entice off-road enthusiasts. The Mojave Desert also includes three [[California State Parks]], the [[Antelope Valley California Poppy Reserve]], in [[Lancaster, California|Lancaster]], [[Saddleback Butte State Park]], in [[Hi Vista, California|Hi Vista]] and [[Red Rock Canyon State Park (California)|Red Rock Canyon State Park]]. [[Hoover Dam]] is a popular tourist destination.

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]], {{convert|17|mi}} west of Las Vegas, both of which are managed by the Bureau of Land Management.


=== History ===
Among the more popular and unique tourist attractions in the Mojave is the self-described [[world's tallest thermometer]] at {{convert|134|ft}} high, which is along [[Interstate 15 in California|Interstate 15]] in Baker, California. The newly renovated [[Kelso Depot, Restaurant and Employees Hotel|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.
Before the European colonization of North America, tribes of Native Americans, such as the [[Mohave people|Mohave]], were [[hunter-gatherer]]s living in the Mojave Desert.<ref name=MojaveNPS>{{cite web|url=http://www.nps.gov/moja/historyculture/index.htm|title=History & Culture|work=Mojave National Preserve|publisher=National Park Service}}</ref>


European explorers started exploring the deserts beginning in the 18th century. [[Francisco Garcés]], a [[Franciscan]] friar, was the first explorer of the Mojave Desert in 1776.<ref name=MojaveNet>{{cite web|url=http://mojavedesert.net/people/garces.html|title=Fr.

Several attractions and natural features are in the [[Calico Mountains (California)|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 [[Bureau of Land Management|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, California|Yermo]], is believed by some archaeologists, including the late [[Louis Leakey]], to show the earliest evidence with [[Lithic analysis|lithic]] [[stone tools]] found here of human activity in North America. The [[Calico Peaks]] scenically rise above all the destinations.


Later, as American interests expanded into California, American explorers started probing the California deserts. [[Jedediah Smith]] travelled through the Mojave Desert in 1826, finally reaching the [[San Gabriel Mission]].<ref>{{cite book|first=Bil|last=Gilbert|title=The Trailblazers|url=https://archive.org/details/trailblazers00time|url-access=registration|publisher=Time-Life Books|year=1973|pages=[https://archive.org/details/trailblazers00time/page/96 96]–100, 107}}</ref><ref>{{cite book|first=Alson J.|last=Smith|title=Men Against the Mountains: Jedediah Smith and the South West Expedition of 1826–1829|url=https://archive.org/details/menagainstmounta00smit|url-access=registration|location=New York|publisher=John Day Co.|year=1965}}</ref>

===Flora===
{{Further|List of flora of the Mojave Desert region}}
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]]'').<ref>{{Cite book|url=https://archive.org/details/vegetationflorao0001shre |url-access=registration |page=[https://archive.org/details/vegetationflorao0001shre/page/3 3] |title=Vegetation and Flora of the Sonoran Desert|last=Shreve|first=Forrest|last2=Wiggins|first2=Ira Loren|date=1964-01-01|publisher=Stanford University Press|isbn=9780804701631|language=en}}</ref>

Various habitats and regions of the Mojave Desert have been protected by statute. Notably, Joshua Tree National Park, Death Valley National Park, and the Mojave National Preserve by the California Desert Protection Act of 1994. ([[Public Law (United States)|<abbr>Pub.L.</abbr>]] 103–433). Various other federal and state land agencies have protected regions within the Mojave Desert. These include [[Antelope Valley California Poppy Reserve]], which protects the fields of California poppies, [[Mojave Trails National Monument]], [[Desert Tortoise Natural Area]], [[Arthur B.

== Soil and plants conditions ==
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 decrease as you move down the gradient, where you can also find low alkalinity. This erosional gradient is a habitat for many plant communities. As you go up the gradient of the desert, you will find more [[pediment (geology)|pediment]] and [[alluvial fan]] soil. In these areas, the flora is mostly succulents. As you move down the gradient, this area is described to be the upper and lower [[bajada (geography)|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 taproots, and ephemerals.

==West Mojave plan litigation==
{{reflist|group=lower-alpha}}
The U.S. Bureau of Land Management (BLM) manages public lands in the Mojave Desert as part of its "crown jewels of the [[Western United States|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 Off-Highway Vehicle Area|Rasor]], Spangler Hills, Stoddard Valley, Dove Spring Canyon, [[Dumont Dunes]], and the world's largest open off-road vehicle use area, [[Johnson Valley, California|Johnson Valley]]. Open areas designated for unrestricted vehicle travel in the western Mojave Desert total {{convert|363480|acre|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.".<ref>{{cite web|date=April 27, 2007|title=Desert Lawsuit Settlement|url=http://www.blm.gov/ca/st/en/fo/cdd/lawsuit.html|work=California Desert District|publisher=[[Bureau of Land Management]]|access-date=2010-01-12|url-status=dead|archive-url=https://web.archive.org/web/20100410122927/http://www.blm.gov/ca/st/en/fo/cdd/lawsuit.html|archive-date=April 10, 2010}}<br/>a. {{cite web|date=December 20, 2004|title=Order Re: Defendants' motion to alter or amend the judgment and plaintiffs' motion for injunctive relief|url=http://www.blm.gov/pgdata/etc/medialib//blm/ca/pdf/pdfs/caso_pdfs.Par.ba8f28ba.File.pdf/Ilston.ruling.12.30.04.pdf|publisher=[[United States District Court for the Northern District of California]]|access-date=2010-01-12|url-status=dead|archive-url=https://web.archive.org/web/20090612050659/http://www.blm.gov/pgdata/etc/medialib/blm/ca/pdf/pdfs/caso_pdfs.Par.ba8f28ba.File.pdf/Ilston.ruling.12.30.04.pdf|archive-date=June 12, 2009}}</ref>{{Rp|a}} A new biological opinion was subsequently issued and BLM's open wash designation in the NECO planning area was reinstated.

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.<ref name=wil/> 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).<ref name=merc/> 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 (United States)|The Wilderness Society]], who together initiated the legal challenge in late 2006.<ref name=lat/>

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.<ref>{{cite news|url=http://www.pe.com/localnews/stories/PE_News_Local_D_offroad01.283e22a.html|title=Judge: Redo off-roading routes in Mojave Desert|newspaper=Press-Enterprise|first=David|last=Danelski|date=31 January 2011}}</ref>

The Mojave Desert (/mˈhɑːvi, mə-/ moh-HAH-vee, mə-;[3][4][5] Mohave: Hayikwiir Mat'aar;[6] 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.[7][2] Named for the indigenous Mohave people, it is located primarily in southeastern California and southwestern Nevada, with small portions extending into Arizona and Utah.[8][2]

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.

The 54,000 sq mi (140,000 km2) desert supports a number of human activities, including recreation, ranching, and military training.[9] The Mojave Desert also contains various silver, tungsten, iron and gold deposits.[10]: 124 

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. Mojave is a shortened form of Hamakhaave, an endonym in their native language, which means "beside the water".[11]

Geography

The Joshua tree (Yucca brevifolia) is endemic and exclusive to the Mojave Desert.[12]

The Mojave Desert is a desert bordered to the west by the Sierra Nevada mountain range and the California montane chaparral and woodlands, and to the south and east by the Sonoran Desert. The boundaries to the east of the Mojave Desert are less distinctive than the other boundaries because there is no presence of an indicator species, such as the Joshua tree (Yucca brevifolia),[13] which is endemic to the Mojave Desert. The Mojave Desert is distinguished from the Sonoran Desert and other deserts adjacent to it by its warm temperate climate, as well as flora and fauna such as ironwood (Olneya tesota), blue Palo Verde (Parkinsonia florida), chuparosa (Justicia californica), spiny menodora (Menodora spinescens), desert senna (Cassia armata), California dalea (Psorothamnus arborescens), California fan palm (Washingtonia filifera) and goldenhead (Acamptopappus shockleyi). Along with these other factors, these plants differentiate the Mojave from the nearby Sonoran Desert.[2]

The Mojave Desert is bordered by the San Andreas fault to the southwest and the Garlock fault to the north. The mountains elevated along the length of the San Andreas fault provide a clear border between the Mojave Desert and the coastal regions to the west.[10] The Garlock fault separates the Mojave Desert from the Sierra Nevada and Tehachapi mountains, which provide a natural border to the Mojave Desert. There are also abundant alluvial fans, which are called bajadas, that form around the mountains within the Mojave Desert and extend down toward the low altitude basins,[13] which contain dried lake beds called playas, where water generally collects and evaporates, leaving large volumes of salt. These playas include Rogers Dry Lake, and China Lake. Dry lakes are a noted feature of the Mojave landscape.[2] 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 Devil's 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 Devil's Playground.

There are very few surface rivers in the Mojave Desert, but two major rivers generally flow underground. One is the intermittent Mojave River, which begins in the San Bernardino mountains and disappears underground in the Mojave Desert.[14] The other is the Amargosa River, which flows partly underground through the Mojave Desert along a southward path.[15] The Manix, Mojave, and the Little Mojave lakes are all large but shallow.[13]: 7  Soda Lake is the principal saline basin of the Mojave Desert. Natural springs are typically rare throughout the Mojave Desert,[13]: 19  but there are two notable springs, Ash Meadows and Oasis Valley. Ash Meadows is formed from several other springs, which all draw from deep underground. Oasis Valley draws from the nearby Amargosa River.

Climate

Extremes in temperatures throughout the seasons characterize the climate of the Mojave Desert. Freezing temperatures as well as strong winds are not uncommon in the winter, as well as precipitation such as rain and snow in the mountains. In contrast, temperatures above 100 °F (38 °C) are not uncommon during the summer months.[16] There is an annual average precipitation of 2 to 6 inches (51 to 152 mm), although regions at high altitudes such as the portion of the Mojave Desert in the San Gabriel mountains may receive more rain.[10][8] Most of the precipitation in the Mojave comes from the Pacific Cyclonic storms that are generally present passing eastward in November to April.[10] Such storms generally bring rain and snow only in the mountainous regions, as a result of the effect of the mountains, which creates a drying effect on its leeward slopes.[10]

During the late summer months, there is also the possibility of strong thunderstorms, which bring heavy showers or cloudbursts. These storms can result in flash flooding.[17]

A powerful High Desert summer storm sweeps rapidly across the Mojave Desert.

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 fires by serving as a fuel bed. This has significantly altered many areas of the desert. At higher elevations, fire regimes are regular but infrequent.[18]

Cities and regions

Las Vegas is in the Mojave Desert.

While the Mojave Desert is generally sparsely populated, it has increasingly become urbanized in recent years.[8][2] The metropolitan areas include Las Vegas, the largest urban area in the Mojave and the largest urban area in Nevada with a population of about 2.3 million.[26] St. George, Utah, is the northeasternmost metropolitan area in the Mojave, with a population of around 180,000 in 2020, and is located at the convergence of the Mojave, Great Basin, and Colorado Plateau. The Los Angeles exurban area of Lancaster-Palmdale has more than 400,000 residents, and the Victorville area to its east has more than 300,000 residents.[8] 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. 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.

The Mojave Desert has several ghost towns. The most significant are the silver and copper-mining town of Calico, California, and the old railroad depot of Kelso, California. 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 construction of Interstates. CA SR 14, Interstate 15, Interstate 40, CA SR 58, CA SR 138, US Route 95, and US Route 395 are the main highways that traverse the Mojave Desert.

Geology

Rock formations in Joshua Tree National Park

The rock that forms the Mojave Desert was likely created under shallow water in the Precambrian.[13]: 21 [10]: 115  Sedimentary processes left large deposits of limestones, silicates, and dolomites. During the Paleozoic era, the area that is now the Mojave was again likely submerged under a greater sea.[10]: 116  During the Mesozoic era, major tectonic activities such as thrust faulting and folding resulted in distinctive shaping as well as intrusion.[13][10]: 116  During the Cenozoic, more tectonic deformation occurred whilst the Mojave was partly submerged. Major volcanic activity is thought to have occurred during the Oligocene. Large downpours during the Miocene likely significantly eroded the rock in the Mojave and accelerated deposition.[10]: 116 

The Mojave Desert is a source of various minerals and metallic materials. Due to the climate, there is an accumulation of weathered bedrock, fine sand and silt, both sand and silt sediments becoming converted into colluvium.[27] The deposits of gold, tungsten, and silver have been mined frequently prior to the Second World War.[10]: 124  Additionally, there have been deposits of copper, tin, lead-zinc, manganese, iron, and various radioactive substances but they have not been mined for commercial use.[10]: 124 

Ecology

Flora

The flora of the Mojave Desert consists of various endemic plant species, notably the Joshua Tree, which is a notable endemic and indicator species of the desert. There is more endemic flora in the Mojave Desert than almost anywhere in the world.[2] Mojave Desert flora is not a vegetation type, although the plants in the area have evolved in isolation because of the physical barriers of the Sierra Nevadas and the Colorado Plateau. Predominant plants of the Mojave Desert include all-scale (Atriplex polycarpa), creosote bush (Larrea tridentata), brittlebush (Encelia farinosa), desert holly (Atriplex hymenelytra), white burrobush (Hymenoclea salsola), and most notably, the Joshua tree (Yucca brevifolia). Additionally, the Mojave Desert is also home to various species of cacti, such as silver cholla (Cylindropuntia echinocarpa), Mojave prickly pear (O. erinacea), beavertail cactus (O. basilaris), and many-headed barrel cactus (Echinocactus polycephalus). Less common but distinctive plants of the Mojave Desert include ironwood (Olneya tesota), blue Palo Verde (Parkinsonia Florida), chuparosa (Justicia californica), spiny menodora (Menodora spinescens), desert senna (Cassia armata), California dalea (Psorothamnus arborescens), and goldenhead (Acamptopappus shockleyi). The Mojave Desert is generally abundant in winter annuals.[13]: 11  The plants of the Mojave Desert each generally correspond to an individual geographic feature. As such, there are distinctive flora communities within the desert.

Fauna

Notable species of the Mojave Desert include bighorn sheep (Ovis canadensis), mountain lions (Puma concolor), black-tailed jackrabbits (Lepus californicus), and desert tortoises (Gopherus agassizii).[2] Various other species are particularly common in the Mojave Desert, such as the LeConte's thrasher (Toxostoma lecontei), banded gecko (Coleonyx variegatus), desert iguana (Dipsosaurus dorsalis), chuckwalla (Sauromalus obesus), and regal horned lizard (Phrynosoma solare). Species of snake include the rosy boa (Lichanura trivirgata), Western patch-nosed snake (Salvadora hexalepis), and Mojave rattlesnake (Crotalus scutulatus). These species can also occur in the neighboring Sonoran and Great Basin deserts.

The animal species of the Mojave Desert have generally fewer endemics than its flora. However, endemic fauna of the Mojave Desert include Kelso Dunes jerusalem cricket (Ammopelmatus kelsoensis), the Kelso Dunes shieldback katydid (Eremopedes kelsoensis), the Mohave ground squirrel (Spermophilus Mohavensis) and Amargosa vole (Microtus californicus scirpensis).[28] The Mojave fringe-toed lizard (Uma Scoparia) is not endemic, but almost completely limited to the Mojave Desert. There are also aquatic species that are found nowhere else,[29] such as the Devils Hole pupfish, limited to one hot spring near Death Valley.[30]

In society

History

Before the European colonization of North America, tribes of Native Americans, such as the Mohave, were hunter-gatherers living in the Mojave Desert.[31]

European explorers started exploring the deserts beginning in the 18th century. Francisco Garcés, a Franciscan friar, was the first explorer of the Mojave Desert in 1776.[32] Garcés recorded information about the original inhabitants of the deserts.

Later, as American interests expanded into California, American explorers started probing the California deserts. Jedediah Smith travelled through the Mojave Desert in 1826, finally reaching the San Gabriel Mission.[33][34]

Human development

In recent years, human development in the Mojave Desert has become increasingly present. Human development at the major urban and suburban centers of Las Vegas and Los Angeles has had an increasingly damaging effect on the wildlife of the Mojave Desert.[2] An added demand for landfill space as a result of the large metropolitan centers of Las Vegas and Los Angeles also has the real potential to drastically affect flora and fauna of the Mojave Desert. Agricultural development along the Colorado river, close to the Eastern boundary of the Mojave Desert, also causes habitat loss and degradation.[8][2] Areas that are particularly affected by human development include Ward Valley and Riverside county. The United States military also maintains installations in the Mojave Desert, making the Mojave a critical training location for the United States Department of Defense.[9] The Mojave Desert has long been a valuable resource for people, and as its human population grows, its importance will only grow. Miners, ranchers, and farmers rely on the desert for a living.[29] The Mojave is also used by the state of California to meet renewable energy objectives. Large tracts of the desert are owned by federal agencies and are leased at low cost by wind and solar energy companies, although these renewable developments can cause their own environmental impact and disturb cultural landscapes and visual resources.[35] Desert Sunlight Solar Farm, one of the largest solar farms in the world, was built approximately five miles from Joshua Tree National Park. An endangered Yuma clapper rail was found dead at the site in 2014, spurring efforts from conservation groups to protect birds from the so-called lake effect, a phenomenon in which birds can mistake the reflective glare of solar panels for a body of water.[36]

Tourism

The Mojave Desert is one of the most popular spots for tourism in North America, primarily because of the international destination of Las Vegas. The Mojave is also known for its scenery, 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 three California State Parks, the Antelope Valley California Poppy Reserve, in Lancaster, Saddleback Butte State Park, in Hi Vista and Red Rock Canyon State Park. Mojave Narrows Park, operated by San Bernardino County, is a former ranch along the Mojave River.

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 Bureau of Land Management also administers Rainbow Basin and Owl Canyon. 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.

Conservation status

The Mojave Desert has a relatively stable and intact conservation status. The Mojave Desert is one of the best protected distinct ecoregions in the United States,[2] as a result of the California Desert Protection Act, which designated 69 wilderness areas and established Death Valley National Park, Joshua Tree National Park, and the Mojave National Preserve.[37] However, the southwest and central east portions of the Mojave Desert are particularly threatened as a result of off-road vehicles, increasing recreational use, human development, and agricultural grazing.[2] The World Wildlife Fund lists the Mojave Desert as relatively "stable/intact".[2]

Various habitats and regions of the Mojave Desert have been protected by statute. Notably, Joshua Tree National Park, Death Valley National Park, and the Mojave National Preserve by the California Desert Protection Act of 1994. (Pub.L. 103–433). Various other federal and state land agencies have protected regions within the Mojave Desert. These include Antelope Valley California Poppy Reserve, which protects the fields of California poppies, Mojave Trails National Monument, Desert Tortoise Natural Area, Arthur B. Ripley Desert Woodland State Park, Desert National Wildlife Refuge, Lake Mead National Recreation Area, Providence Mountains State Recreation Area, Red Cliffs National Conservation Area, Red Rock Canyon State Park, Saddleback Butte State Park, Snow Canyon State Park and Valley of Fire State Park. In 2013, the Mojave Desert was further protected from development by the Desert Renewable Energy Conservation Plan (DRECP), in which the Bureau of Land Management designated 4.2 million acres of public land as protected wilderness as part of the National Conservation Lands of the California Desert. [38]

Cultural significance

The Mojave Desert has served as a backdrop for a number of films. The 2010 video game Fallout: New Vegas takes place in the Mojave Desert, or "Mojave Wasteland" as it is known in its post-apocalyptic future. At least five music videos were recorded in the Mojave Desert:

Photographs related to U2's 1987 album The Joshua Tree were taken in the Mojave Desert.[42]
