Simultaneously, its 20 million acres offer up a multitude of opportunities—from recreation to ranching, from mining to military training—for people.
They are, however, both finite and fragile. The Mojave has long been an invaluable resource for people, and—as its human populations continue to grow—its importance can only increase.
Miners, ranchers and farmers all depend on the desert for their livelihoods. With every branch of the military maintaining an installation in the desert, the Mojave is a critical training location for the U. Department of Defense. Wind and solar energy installations are becoming an increasingly common sight in the desert. Throughout the desert, underground rivers surface into a series of lush oases that support an extraordinary spectrum of life. Meanwhile we continue our conservation efforts on the ground, protecting, for example, the Amargosa River, where more than species are targeted for conservation.
In addition, our study of the ability of desert species to adapt to the heat and aridity of the desert advances our work with other species facing the increasing effects of climate change. The Rainbow Basin is a well-known basin in the Mojave Desert. It doesn't actually look like a basin or a canyon; however, it is refered to as both by scientists and tourists.
In this case the wind and water erosion has created layers of stone, forming a colorful depression in the wall of a mountain. The Rainbow Basin changes constantly when new layers of sediment are revealed by erosion or added by wind. A butte is like a plateau with its very flat top; although, buttes are usually taller than they are wide. The shape of the butte is formed from streams eroding through a plateau.
The top of a butte remains flat because it is protected by the top layer—known as the caprock. Buttes can easily be described as tall hills with steep sides that appear to stand alone. Dunes are formed by wind, and are common in deserts.
Sand and loose sediment is pushed up into a mound or a ridge and continues to be shaped by the wind over time. In some cases wind can carry new sand grains onto dunes to replenish them. The largest dune field in the Mojave Desert are the Kelso Dunes. These particular dunes are formed mainly by grains of feldspar and quartz, and the mounds reach up to feet above the desert floor. Interestingly, the Kelso Dunes were first created by grains of sand blown together from the Mojave River sink; however, there haven't been any new deposits of sand among the Kelso Dunes since they were originally formed.
Pinnacles are large spires of rocks which are formed when spring water combines with other bodies of water. They often collect in groups. The Trona Pinnacles are located in the Mojave Desert and were created by groundwater and lake water mixing to form these unique rock structures. The Trona Pinnacles can be up to 43 meters in height! A playa is a dried out lake bed. Playas don't contain very much vegetation and are made up of lots of clay and silt.
The ground of a playa often appears scaly and cracked because of the heat and lack of water. They are often found in the lowest and flatest area of a desert basin. Occasionally, during wet periods or near water sources, there will be a little bit of water on the surface of the playa.
Playas are a very useful way to discover the history of an area, because the features and characteristics can reveal information about a regions past and present climates. The Mojave Desert can have a wide range of temperatures throughout the day. The Mojave Desert hosts about endemic plant species found in neither of the adjacent deserts. Cactus are usually restricted to the coarse soils of bajadas. Mojave yucca and, at higher elevations desert Spanish bayonet , a narrow-leafed yucca, are prominent.
Creosote bush , shadscale, big sagebrush , bladder-sage, bursages and blackbush are common shrubs of the Mojave Desert. A few examples of desert animals that live in the Mojave Desert include: bats , bighorn sheep , coyotes , black-tailed jack rabbits , foxes , rattlesnakes , and chukwallas.
When the railroads came, the railways created an easier route to the south complete with oases on the bitter-dry deserts. While it was used, the Mojave Road was a route plagued by hostile Indians, a lack of water, long stretches of sand and rough hill climbs. For caravans of travelers and a handful of soldiers, it was a proving ground that brought out the best and the worst of them.
