Salar de Uyuni (or Salar de Tunupa) is the world’s largest salt flat. Photographers flock here to capture the unique landscape. Salar is salt flat in Spanish. Salar de Tunupa is 10,582 km2 (4,086 sq mi) which is roughly 100 times the size of the Bonneville Salt Flats in the US and the size of Jamaica. It is located in the Potosí and Oruro departments in southwest Bolivia. The elevation is 3,656 m (11,995 ft) above sea level.
It is covered by a few meters of salt crust, which has an extraordinary flatness with the average altitude variations within one meter over the entire area of the Salar. The crust serves as a source of salt and covers a pool of brine, which is exceptionally rich in lithium. It contains 50% to 70% of the world’s lithium reserves.
Salar de Tunupa is estimated to contain 10 billion tonnes of salt, of which less than 25,000 tonnes is extracted annually.

The large area, weather conditions, clear skies, and the exceptional flatness of the surface make the Salar an ideal object for calibrating the altimeters of Earth observation satellites.
