Second on the list is the Salar de Uyuni. This is the world’s biggest salt flat at 10,582 km² or 4,085 square miles. It is located in the southwest of Bolivia, close to the crest of the Andes, 3,650 meters high. The most important minerals found in the salar are halite and gypsum.Due to its huge size, smooth surface, high surface reflectivity when covered with shallow water, and minimum elevation deviation, Salar de Uyuni makes an ideal target for the testing and calibration of remote sensing instruments on orbiting satellites used to learn the Earth.
alar de Uyuni is estimated to include 10 billion tons of salt, of which less than 25,000 tons is extracted yearly. Every November, Salar de Uyuni is also the breeding grounds for 3 species of South American flamingoes: Chilean, James’s and Andean flamingoes.
