English: High atop the Patagonian Andes sits a stunning natural area filled with mountains, lakes, forests and glaciers. Los Glaciares National Park is situated in the Santa Cruz Province of Argentina and has a total surface area of about 600,000 hectares and was declared a UNESCO World Heritage Site in 1981. The park takes its name from the numerous glaciers which cover about half of the property, many of which are fed by the massive South Patagonia Ice Field.

The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite acquire this true-color image on November 20, 2016.

Over time the melting of glaciers have formed the three lakes seen in this image. From north to south they are Lago San Martin, Lago Viedma, and Lago Argentino. The Upsala, Onelli, and Perito Moreno Glaciers calve into Lago Argentino. Perito Moreno is famous for its unusual behavior. The front of the massive glacier rises up to 60 meters (197 feet) high continuously moves forward, eventually blocking a narrow channel formed by Lago Argentino. Eventually, the pressure increases on the glacial tongue until it ruptures dramatically, calving icebergs into the waters of the lake.
