This detailed view was taken with an 800 mm lens from the International Space Station on 10 January, 2004. The image shows the lower end of the Viedma Glacier that flows into Lake Viedma, one of three major glacially formed lakes on the Patagonian side of the southern Andean ice sheet, at 50 degrees South.  The image reveals the slender dark lines of rock material (moraine) which is carried in the slowly flowing ice. Lighter lines at right angles are patterns of crevasses. The glacier diverges into two lakes where calved icebergs can be seen floating in the lakes. The glacier here is about 1.8 km wide.
