Muir and Riggs Glaciers, Muir Inlet, Alaska - 2004
By Communications and Publishing
2004 (approx.)
Detailed Description
As this picture of Muir and Riggs Glaciers 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
