Colorado Desert Geomorphic Province

The Colorado Desert province is a low-lying barren desert basin, about 245 feet below sea level in part, is dominated by the Salton Sea. The province is a depressed block between active branches of alluvium-covered San Andreas Fault with the southern extension of the Mojave Desert on the east. It is characterized by the ancient beach lines and silt deposits of extinct Lake Cahuilla.
