Malaspina Glacier, Alaska Alaskan Glacier
This is a 3-D view of Malaspina Glacier. Glaciers erode rocks, carry them down slope, and deposit them at the edge of the melting ice, typically in elongated piles called moraines. The moraine patterns at this glacier have huge contortions that result from the glacier crinkling as it gets pushed from behind by the faster-moving valley glaciers.

This image was created from a Landsat satellite image and an elevation model generated by the Shuttle Radar Topography Mission.
