Lake Viedma
From Freepedia
Lake Viedma, approximately 50 miles (80 kilometers) long in extreme southwestern Argentina, is a major elongated trough lake formed from melting glacial ice (lake is located at 49°35′ S 72°30′ W). The lake is fed primarily by the Viedma Glacier at the western end of the lake. The Viedma Glacier measures 3 miles (5 kilometers) wide at its terminus at Lake Viedma. The brown landscape resulted from ice scouring, which left virtually no vegetation on the steep-walled valleys.
