Argentina - September 29th, 2009

The Central Andean dry puna is an ecoregion located in the Andean High plateau, in South America. It is a part of the Puna grassland, occupying the southwestern portion of the Altiplano, and is located east of the Atacama Desert.

Salt Flats, locally known as Salares, are a characteristic feature of this ecoregion. Among the largest of these is the Salar de Arizaro, visible as a large, flat light grey area in this orthorectified image.

It is the largest salar of Puna, Argentina, with a surface area of 1500 km2, and the third largest salar in the Andes, after the Salar de Uyuni in Bolivia and the Salar de Atacama in Chile. The salar is used for metallic and non-metallic mining, as is it rich in salt, iron, marble, onyx and copper.

Also visible in the upper left corner, near the salar, is the Aracar Volcano. It is a large conical stratovolcano in northwestern Argentina, just east of the Chilean border. It has an uneroded summit crater about 1.5 km in diameter which contains a small crater lake.

It is located on the edge of the Puna de Atacama, a high desert plateau east of the Atacama Desert. The only observed volcanic activity was a possible steam or ash plume on March 28, 1993, seen from the village of Tolar Grande about 50 km southeast of the volcano.
