The U.S. Department of Energy recently discovered the world’s largest Lithium reserve beneath California’s Salton Sea. It is a shallow, saline lake located in the lower Colorado Desert, southern California, USA.  It is a geological depression tucked between mountain ranges and lying below sea level. The area that is now the lake was formerly a salt-covered sink or depression (a remnant of prehistoric Lake Cahuilla) about 280 feet (85 metres) below sea level until 1905–06, when diversion controls on the Colorado River broke a few miles below the California-Mexico border and floodwaters rushed northward, filling the depression.
