Salar de Uyuni is the largest salt flat in the world, it has a measurement of 10,582 km squared (4,086 miles squared). Salar de Uyuni is also known as Salar de Tunupa which can be translated from Spanish as ‘salt at enclosure’. It is located in Potosí in southwest Bolivia, near the crest of the Andes and is at an elevation of 3,656 meters (11,995 ft) above mean 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 lithium reserves, which is in the process of being extracted. Whilst some salt is extracted from Salar de Uyuni, it is estimated that the at contains 10 billion tonnes of salt. Salar de Uyuni has little wildlife, but has 80 species of visiting and migrating birds. These salt ats are a large tourist attraction for people to come and take photos
because it makes the salt at also the largest natural mirror.
