The Mojave Desert area of southern California is a stunning mosaic of rugged mountain ranges, ancient lava flows, and spectacular sand dunes. It is a landscape defined by scarcity and shaped by travel. The area exemplifies the remarkable ecology of the Mojave Desert, where the hearty insistence of life is scratched out from unrelenting heat and dryness. This punishing environment has also forged the unique human history of the area, from ancient settlements uprooted by a changing climate to the armies of General Patton, as they trained for battle in North Africa. With historic American trading routes, trails followed by Spanish explorers, a transcontinental rail line, and the Nations most famous highway, the Mojave Desert area tells the American story of exploration, migration, and commerce.
