Lake Viedma (Spanish: Lago Viedma), approximately 50 miles (80 kilometers) long in southern Patagonia near the border between Chile and Argentina. It's a major elongated trough lake formed from melting glacial ice (lake is located at ). 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 is a result of ice scouring, which left virtually no vegetation on the steep-walled valleys.
Although most of the lake lies in Argentine territory, the western shores of the lake reach the Southern Patagonian Ice Field in an area where the border remains undefined. Even if the Chilean territorial claims don't reach the shores, that could change as the glacial tongue in the lake melts.
