Salar de Uyuni is the world’s largest salt flat, or playa, at over 10,000 square kilometres and is located at an elevation of 3,656 meters above sea level.
The Salar was formed as a result of transformations between several prehistoric lakes. It is covered by a few meters of salt crust. 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 known lithium reserves.
Every November, Salar de Uyuni is the breeding ground for three South American species of flamingo: the Chilean, Andean, and rare James’s flamingos. About 80 other bird species are present, including the horned coot, Andean goose, and Andean hillstar.
