The Perito Moreno Glacier is a glacier located in the Los Glaciares National Park in southwest Santa Cruz province, Argentina. It is one of the most important tourist attractions in the Argentine Patagonia.
The 250 km2 ice formation, and 30 km in length, is one of 48 glaciers fed by the Southern Patagonian Ice Field located in the Andes system shared with Chile. This icefield is the world's third largest reserve of fresh water.
The terminus of the Perito Moreno Glacier is 5 kilometres wide, with an average height of 74 m above the surface of the water of Lake Argentino, in Argentina. It has a total ice depth of 170 metres.
Los Glaciers National Park is an area of exceptional natural beauty, with rugged, towering mountains and numerous glacial lakes, including the great Lago Argentino. This vast alpine area includes the Patagonian ice field which occupies about half of the park. Extending over 14,000 km2, the ice field is the largest ice mantle outside Antarctica. It has a total of 47 glaciers and a further 200 smaller glaciers are independent of the main ice field.
