The Los Glaciares National Park is an area of exceptional natural beauty, with rugged, towering mountains and numerous glacial lakes, including Lake Argentino, which is 160 km long. At its farthest end, three glaciers meet to dump their effluvia into the milky grey glacial water, launching massive igloo icebergs into the lake with thunderous splashes.
Los Glaciares National Park is located in the Southwest of Santa Cruz Province in the Argentine part of Patagonia. Comprised of a National Park and a National Reserve it has a total surface area of 600,000 hectares.
Los Glaciares owes its name to the numerous glaciers covering roughly half of the World Heritage property.
Many of these glaciers are fed by the massive South Patagonian Ice Field, the most extensive South American relict of the glaciological processes of the Quaternary Period.
In addition, there are impressive glaciers independent of the main ice field and therefore constitutes a massive freshwater reservoir.
The Upsala, Onelli and Perito Moreno Glaciers calve into the icy and milky waters of the huge Lake Argentino, which is partly included in the property.
he most striking sight is the famous Perito Moreno Glacier which blocks a narrow channel formed by Lake Argentino thereby raising the water level temporarily which in turn causes regular thunderous ruptures of the glacier tongue into the lake.
