The Colorado Desert extends from San Gorgonio Pass in southern California to the Colorado River Delta in northern Mexico. The region formed by partial collapse of the Coastal Mountain Range, its western boundary, and is significantly lower in elevation than the Mojave Desert to the northeast. Much of the Colorado Desert lies below 1000 feet, and its lowest point, located in the Salton Sea basin, is 275 feet below sea level. While the Coastal Range prevents Pacific moisture from reaching far inland, the Colorado Desert typically experiences two wet periods, one in Winter and the other in late Summer. Following good Winter precipitation, the Colorado Desert springs alive in a rich diversity of wildflowers, celebrated in this series of six images.
