Ancient Lake Cahuilla High Water Mark
Lake Cahuilla was an ancient freshwater lake in the Salton Trough of southern California. It covered parts of the Coachella, Imperial and Mexicali valleys and was formed when the Colorado River overflowed its banks or was diverted northwest by its own sediments, which temporarily blocked the flow to the Gulf of California (Sea of Cortez).
