One Of the World's Largest Mirror

It's also called "Salar de Uyuni" (salar  in Spanish is salt flat ) is currently the world’s largest salt flat at 10,582 square kilometers (4,086 sq mi). 

No, This is not  a Photoshop trick..!!

 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.

 Salar de Uyuni is also a climatological transitional zone since the towering tropical cumulus congestus and cumulus incus clouds that form in the eastern part of the salt flat during the summer cannot permeate beyond its drier western edges, near the Chilean border and the Atacama Desert.

 Salar de Uyuni is part of the Altiplano of Bolivia in South America. The Altiplano is a high plateau, which was formed during uplift of the Andes mountains. The plateau includes fresh and saltwater lakes as well as salt flats and is surrounded by mountains with no drainage outlets
