Southern Patagonian Ice Field

The Southern Patagonian Ice Field is the world's second-largest contiguous ice field outside the polar regions, one of two surviving remnants of the Patagonian Ice Sheet that once covered all of southern Chile during the last glacial period. It stretches about 350 kilometers north to south along the Southern Patagonian Andes on the border of Chile and Argentina, covering roughly 16,800 square kilometers, most of it, about 14,200 square kilometers, on the Chilean side. The ice field feeds dozens of glaciers, including the well known Perito Moreno, Viedma and Upsala glaciers, and supplies the Santa Cruz River and Lakes Argentino and Viedma; parts of it lie within Bernardo O'Higgins, Torres del Paine and Los Glaciares national parks. Two little-explored volcanoes, Lautaro and Viedma, lie hidden beneath the ice, and the field as a whole is retreating as the climate warms.
