Valdés Peninsula and Lakes in Argentine Patagonia42.5S 64W
Protruding from the coast of Chubut Province in Argentine Patagonia is the Valdés Peninsula (or Península Valdés in Spanish). Two gulfs border the stretch of land connecting the peninsula to the mainland: Golf San José (above) and Golfo Nuevo (below).
Although much of the 3,625 km² peninsula is barren land, its salt lakes and shoreline provide an important habitat for sea mammals and birds, and is recognized as a nature reserve and UNESCO World Heritage site.
In the upper left quadrant, several lakes can be seen clustered around the Neuquén River (above) and the Limay River (below). All of the lakes are artificial: the southernmost one is a reservoir created by the El Chocón Dam, the pair of reservoirs to the north are part of the Cerros Colorados Complex, and the one to the east is Pellegrini Lake, made by filling a natural depression with water from the Neuquén River.
