This interesting image shows the world’s largest glacier, Lambert Glacier in Antarctica, and icefall that flows into it. Ice flows like water, albeit much more slowly. Cracks can be seen in this icefall as it bends and twists on its slow descent 1300 feet (400 meters) to the glacier below. The image was taken by the Landsat-7 satellite on December 2, 2000 and is a false-color composite made from infrared, red and green wavelengths. The image has also been sharpened using the sensor’s panchromatic band.
