Occupying over 10,000km2, the vast Salar de Uyuni lies at the southern end of the Altiplano, a high plain of inland drainage in the central Andes. On the whole, the Salar de Uyuni is very flat, with a surface elevation variation of less than 1m. The Salar serves as the major transport route across the Bolivian Altiplano and is a major breeding ground for several species of flamingos. From the image it is clear that the lake is located at 3700m in the Andes Mountains.

The local scenery on the ground of Incahuasi island in the center of the Salar is as follows.
