[1] Perito Moreno Glacier (Argentina)Photographed by astronauts on the International Space Station,February 21, 2012 - an Earth Observatory Image of the Day

One of the largest in Patagonia at 30 kilometers long, this glacier descends from the Southern Patagonian Icefield (TOP of FIRST IMAGE)—2100 meters elevation (6825 feet) in the Andes Mountains—down into the water and warmer altitudes of Lago Argentino at 180 meters above sea level.
Perito Moreno periodically cuts off the major southern arm (known as Brazo Rico) of Lake Argentino, advancing right across the lake until it meets the opposite shoreline, and the ice tongue is “grounded” (not floating) so that it forms a natural dam.

[2] Zooming in, we see the glacier extend across Lago Argentino.
[3] Zooming even more, an ice cave.
[4] [5] Getting really close now, sergejf on Flickr shows us some melt pools. December 22, 2012
