Spine of the Andes and Salt Flats in Argentina38.7S 62.9W
While the spine of the Andes Mountains, running along the Chile-Argentina border, appears bright white due to snowfall, it is not the only bright white feature on the South American landscape nearby: several salt flats are visible to the east, in Argentina. Visible near the foothills of the Andes are the Salinas Grandes, a salt desert in the Córdoba and Santiago del Estero provinces of the Sierras de Córdoba that covers an area of 3,200 mi² (8,290 km²). Further east, salt flats can be seen by the northern shores of the Mar Chiquita, an endorheic salt lake that is the largest of the naturally occurring saline lakes in Argentina. Here, some dust (probably salt and other minerals) can be seen blowing off the Mar Chiquita salt flats and southward over the lake.
