The photo above showing the largest salt flat in Chile, Salar de Atacama, was taken 34 mi (55 km) south of San Pedro de Atacama, on April 13, 2009. Salar de Atacama is the largest source of lithium active in the world today and is the lightest elemental metal in the periodic table. Lithium is used in the production of batteries as well as in soldering and for lubrication. At the horizon, the Licancabur volcano (19,400 ft or 5,913 m) can be seen.
