Salt Flats – Bolivia
The Salt Flats or also known as Salar de Uyuni, is the largest salt desert around 11,000 km sq. The Salar was formed as a result of transformations between several prehistoric lakes. 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 Salar contains large amounts of sodium, potassium, lithium, magnesium and borax.
