Desert solitude in Southern California. Mojave Desert is known for its Joshua Trees. "The Mojave Desert is bound in part on the western end by the Tehachapi together with the San Gabriel and San Bernardino mountain ranges. The mountain boundaries are quite distinct since they have been created by the two largest faults in California: the San Andreas and the Garlock. Its northern and eastern boundaries are less distinct. One way to determine location is by observing the presence of Joshua Trees. The Mojave Desert receives less than 6 inches of rain a year and is generally between 3,000 and 6,000 feet in elevation. The Mojave Desert also contains the Mojave National Preserve, Joshua Tree National Park and the lowest-hottest place in North America: Death Valley, where the temperature can approach 120F in late July and early August."
