4) “Salar de Uyuni”

·         “Salar de Uyuni” - Bolivia (World's Largest Natural Mirrors):

3,800 sq miles of salt flat spread out across Bolivia's remote southwest. Salar de Uyuni is the largest salt flat in the world, an endless sheet of hexagonal tiles (created by the crystalline nature of the salt), dotted with pyramids of salt. During the wet season, the salt desert is transformed into a enormous salt lake, albeit one that is only six to twenty inches deep, traversable by both boat and truck. During this time, the shallow salt lake perfectly mirrors the sky, creating bizarre illusions of infinity. In the middle of this seemingly infinite salty lake is a hotel built entirely out of—naturally—salt.
