Salinas Grandes and Mar Chiquita, Argentina30.7S 62.8W
Clouds and snow cap the foothills of the Andes Mountains in western Argentina. Visible below are Mar Chiquita (right edge) and the Salinas Grandes (center). The Salinas Grandes are a salt desert in the Córdoba and Santiago del Estero provinces of the Sierras de Córdoba in Argentina that covers an area of 3,200 mi² (8,290 km²).
Mar Chiquita, meaning “Little Sea”, is actually an endorheic salt lake located in the northeast of the province of Córdoba, in central Argentina. It is the largest of the naturally occurring saline lakes in Argentina. The lake occupies the southern part of a depression that measures about 50 miles/80 km (north–south) by 28 miles/45 km (east–west). Its surface area varies considerably, given its shallow depth (about 10 m), and ranges between 2000 and 4500 km² (800 and 1800 mi²).
