Argentina – January 26th, 2013

In Southern Santa Cruz province, Argentina’s Lake Viedma (center) is a large -1.088 km2 (420 sq.mi)- body of water, slightly smaller than Lake Argentino (below) into which it flows. It is located next to the Southern Ice Field and Viedma Glacier flows into the lake.

Argentino Lake is the biggest freshwater lake in Argentina, with a surface area of 1,466 km2 (566 sq mi) (maximum width: 20 mi (32 km)). It has an average depth of 150 m (492 ft), and a maximum depth of 500 m (1,640 ft). The fjords at the northwestern end of Lago Argentino are fed by five glaciers, the largest of which is the Upsala glacier. Scientists have predicted that climate change may cause the lake’s temperature to increase by 2ºC or 3ºC.
