Lake Titicaca and Salar de Uyuni, Bolivia and Peru15.7S 69.3W
Located between Bolivia and Peru, Lake Titicaca is situated at a very high altitude, at over 3800 meters above sea level. Here, its deep waters appear almost black in color.
Visible to the southeast of the lake is the Salar de Uyuni (or Salar de Tunupa), the world’s largest salt flat at 10,582 square kilometers (4,086 sq mi). It is located in the Potosí and Oruro departments in southwest Bolivia, near the crest of the Andes, and is elevated 3,656 meters (11,995 ft) above the mean sea level. The salar’s white color is due to the fact that it is covered by a few meters of salt crust.
