Lake Poopó and Salar de Uyuni, Bolivia – June 13th, 200918.7S 67W
Clouds hug the coast of Chile (bottom) and Peru (left), as well as the snow-capped peaks of the Andes Mountains.
The rest of the image is cloud free, permitting a clear view of the arid terrain in Peru (left), Bolivia (center) and Chile (bottom), and the lush rainforest of Brazil (top).
The extensive white patch is the Salar de Uyuni, in Bolivia, the world’s largest salt flat.
Above it, in a shallow depression in the Altiplano Mountains, is Lake Poopó. This large saline lake, which has been designated as a site for conservation under the Ramsar Convention, is located at an altitude of approximately 3,700 meters.
The lake is about 90 km by 32 km wide, and the permanent part of the lake body covers approximately 1,000 km².
Lake Poopó receives most of its water from the Desaguadero River, which links it with Lake Titicaca (upper left quadrant) at the north end of the Altiplano.
Since the lake lacks any major outlet and has a mean depth of no more than 3 m, the surface area varies greatly. Here, some of its waters are greenish in color, while parts of its shores are flanked by white salt flats.
