The Lambert Glacier in Antarctica is the world’s largest glacier. The focal point of this image is an icefall that feeds into the 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 400 metres to the glacier below.
This image was captured by the Landsat 7 satellite on 1 December 2000.
