This Envisat image, acquired on 3 June 2011, is dominated by southern Argentina, with the mountainous terrain of the Andes in Chile to the west. In the centre, two lakes in Argentina’s Chubut province are visible. Lake Musters’ depth of about 20 m gives it a dark hue, while Lake Colhué Huapi fills a shallow depression, about 2 m deep. The inlet cutting into the east coast of Argentina is the San Jorge Gulf, measuring about 228 km at its mouth. The bright white spot in the lower-left corner of the image is the Northern Patagonian Ice Field in southern Chile.
