The Lambert Glacier in Antarctica is the worlds largest glacier. The focal point of this image
is an icefall that feeds into the Lambert glacier from the vast ice sheet covering the polar
plateau. Ice flows like water, albeit much more slowly. Cracks can be seen in this icefall as
it bends and twists on its slow-motion descent 1300 feet (400 meters) to the glacier below.
This image was acquired by
Landsat 7s Enhanced Thematic Mapper plus
(ETM+) sensor on December 2, 2000. This is a false-color composite image made using
infrared, red, and green wavelengths. The image has also been sharpened using the sensors
