This image of a Patagonian glacier was aqcuired by the
Advanced Spaceborne Thermal Emission and Reflection
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.
