Los Glaciares National Park (Spanish: The Glaciers) is a national park in the Santa Cruz Province, in Argentine Patagonia. It comprises an area of 4459 km². In 1981 it was declared a World Heritage Site by UNESCO. The national park, created in 1937, is the second largest in Argentina. Its name refers to the giant ice cap in the Andes range that feeds 47 large glaciers, of which only 13 flow towards the Atlantic Ocean. The ice cap is the largest outside of Antarctica and Greenland. In other parts of the world, glaciers start at a height of at least 2,500 meters above mean sea level, but due to the size of the ice cap, these glaciers begin at only 1,500m, sliding down to 200m AMSL, eroding the surface of the mountains that support them. The mountains hold most of the humidity from the Pacific Ocean, letting through only the ice coldness (annual average of 7.5 °C) and creating the arid Patagonian steppe on the Argentine side of the range. This area is habitat for ñandúes, guanaco, cougar, and gray fox, the latter who has suffered from the invasion of the cattle industry and are endangered. (Full article...)
