It was part of a prehistoric salt lake, Lago Minchin, which once covered most of southwest Bolivia. When it dried up, it left a couple of seasonal puddles and several salt pans, including the Salar de Uyuni.
When it rains, the salty crust becomes a giant mirror and a giant mirror means giant, double sunsets!
With no place to drain, water collated to form a giant lake. As the prehistoric lake evaporated under the fierce Sun, a thick crust of salt remained, forming what we now recognize as the salt flats of Salar de Uyuni. The world seems to extend to the infinity here.
Unlike any other place on earth, the Salar de Uyuni is breathtakingly beautiful and provides an extraordinary experience that will not be quickly forgotten. Photo Courtesy - rustedufo.livejournal.com
