The Salton Sea, also known as Salton Riviera, was a water formation created by a dam overflow, from the Colorado River, between 1905 to 1907.
In the 1860s, miners harvested salt from the area where the Salton Sea sits. When the overflowing water from the dams entered the former mines, the newly formed Salton Sea became the saltiest body of water in the United States.
Presently, the Salton Sea is a California State Park.
The white beaches are filled with the fish bones and other animals that died from the highly salty water.
