UPSALA GLACIER, ARGENTINA - 25 Oct 2009 - Upsala Glacier, Argentina is featured in this image from the International Space Station. The Southern Patagonian Ice Field of Argentina and Chile hosts some of the most spectacular glaciers in the world, and is second only to Antarctica in size. This detailed photograph illustrates the terminus of Upsala Glacier, located on the eastern side of the ice field. This glacier is the third largest in the Southern Patagonian Ice Field and, like most other glaciers in the region, has experienced significant retreat over the past century. This image was taken during spring in the Southern Hemisphere, and the calving of icebergs release of chunks of ice from the glacier terminus as it enters the waters of Lake Argentina - is visible at left. Two icebergs are of particular interest, as they retain fragments of the moraine that forms a dark line along the upper surface of the glacier. Moraines of the type visible in this image are formed from coarse rock and soil debris that accumulates along the front and sides of a flowing glacier; much like a bulldozer blade pushes material in front of it
