Salar de Atacama

From Wikipedia, the free encyclopedia

Salar de Atacama is the largest salt flat in Chile. It is located 55 km south of San Pedro de Atacama and is surrounded by mountains with no drainage outlets. To the east is enclosed by the main chain of the Andes, while to the west lies a secondary mountain range of the Andes called Cordillera de Domeyko. Large volcanoes dominate the landscape, including the Licancabur, Acamarachi, Aguas Calientes and Láscar. The latter is one of the most active volcanoes in Chile.

The salt flat encompasses 3,000 km², is about 100 km long and 80 km wide, which makes it the Americas's second largest and is also the second in the world, after Salar de Uyuni in Bolivia (10,582 km²).^{[citation needed]}

It contains 40% of lithium world reserves.^{[citation needed]}

Some areas of the salt flat form part of Los Flamencos National Reserve.
