"Salar de Uyuni" is world's largest salt flat(10,582 square kilometers) located in Daniel Campos Province, Potosi, southwest Bolivia.
The salar is formed as the result of transformations between several prehistoric lakes. It is covered by salt crust and is rich in lithium, which is in process of being extracted.
