Tourism map of the Southern Patagonian Ice Field, note the undefined part near
Viedma Lake
Lake Viedma (Spanish: Lago Viedma), approximately 50 miles (80 kilometers) long in southern Patagonia near the border beetwen Chile and Argentina. It's 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.
Even if most of the lake lies in Argentine territory, the western shores of the lake reaches the Southern Patagonian Ice Field in an area where the border remains undifened. Even if the Chilean claims dont reaches the shores that could change as the glacier tounges in the lake melts.
