evidence: Los Glaciares National Park covers the region known as Andes Australes of the Argentine territory, in the Southwest of Santa Cruz province on the shared border with Chile. It was created in 1937 to preserve this vast region dominated by glaciers, with native subantarctic forest and a large number of endemic species of plants and animals. This unique natural wonder has been declared a "World Heritage Site of Humanity" by UNESCO in 1981. The National Park includes a scenario of mountains, lakes and forests, a large portion of the Andes Mountains covered with ice and snow to the west and the arid Patagonian steppe to the east. Los Glaciares owes its name to the presence of numerous glaciers that are fed by the massive South Patagonian Ice Field - the largest ice field in the Southern Hemisphere after Antarctica - which covers almost half of the Park. Also known as Southern Patagonian Icecap, it feeds 47 large glaciers, of which 13 descend towards the Atlantic Sea. In addition there are more than a hundred smaller glaciers independent of the main ice field. [...] Los Glaciares National Park protects a vast region dominated by the glaciers of the Southern Patagonian Ice Field in the Province of Santa Cruz (Argentina). Of gigantic proportions for our human scale, the current ice field and its glaciers are actually a small remnant of what was the last great glaciation, which began 100,000 years ago, had its apogee 20,000 years ago and ended abruptly about 10,000 years or so.
