Death Valley contains salt pans. According to current geological consensus, during the middle of the Pleistocene era there was a succession of inland seas (collectively referred to as Lake Manly) located where Death Valley is today. As the area turned to desert the water evaporated, leaving behind the abundance of evaporitic salts such as common sodium salts and borax, which were subsequently exploited during the modern history of the region, primarily 1883 to 1907
Badwater, a basin located in Death Valley, is the specific location (36° 15' N 116° 49.5' W) of the lowest elevation in North America at 282 feet (86.0 m) below sea level.
