Le parc national Los Glaciares est une aire protégée de 539 300 ha qui se situe dans le sud-ouest de la Patagonie argentine, à la frontière chilienne. Ce parc englobe deux grands lacs d’origine glaciaire et quelques lacs plus réduits, ainsi que quelques montagnes mythiques, comme le Fitz Roy (ou Chaltén), de 3 405 m, et le Cerro Torre, de 3 102 m.

SANTA CRUZ PROVINCE, ARGENTINA - NOVEMBER 28:  The Spegazzini glacier (L) and Heim glacier stand in Los Glaciares National Park, part of the Southern Patagonian Ice Field, the third largest ice field in the world, on November 28, 2015 in Santa Cruz Province, Argentina. The majority of the almost fifty large glaciers in the park have been retreating over the past fifty years due to warming temperatures, according to the European Space Agency (ESA). The United States Geological Survey reports that over 68 percent of the world's freshwater supplies are locked in icecaps and glaciers. The United Nations climate change conference begins November 30 in Paris.  (Photo by Mario Tama/Getty Images)
