Muir and Riggs Glaciers, Muir Inlet, Alaska
Glaciers
As this picture of Muir and Riggs Glaceris in Alaska shows, glaciers are really rivers, but rivers of solid ice instead of liquid water. Just because they are solid does not mean they don't move, though. Glaciers do flow downhill, just very, very slowly.

Resurrection Bay multibeam imagery
Sonar-generated image showing underwater topography and the potential for landslides near the head of Resurrection Bay, Alaska. The terrain looks three times as steep as it occurs naturally. The arrow points to underwater landslide debris from the collapse of a fan-delta following the great Alaskan earthquake of 1964.
