This image of a Patagonian glacier was aqcuired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer. Vegetation appears red in the image, which is a false-color composite of near-infrared, red, and green light displayed as red, green, and blue, respectively.

This large glacier is riddled with crevasses deep cracks in the ice. The semi-circular ridge at the far left of the image is composed of rock and soil carried there by the glacier which was even larger in the past. This type of feature is called a "terminal moraine". The pools of water at the foot of the glacier are light-colored due to the fine silt suspended in them. A braided stream winds through more silt deposited by the glacier and cuts through the terminal moraine about one third of the way down from its top.
