Mojave Desert - Geography

Geography

The Mojave Desert is defined by the mountain ranges creating its xeric conditions; and it also has numerous mountain ranges within it. They 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 thining which pulls open valleys over millions of years. Most of the valleys are internally drained, 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. This area is known for its incised canyons, high mesas and plateaus, and flat strata; a unique geographic locality found nowhere else on earth.
