Icefall, Gibbs Island, Antarctica

Steven Dutch, Professor Emeritus, Natural and Applied Sciences, University of Wisconsin - Green Bay

When water falls over a cliff, it forms a waterfall. When a glacier flows over a cliff, we get an icefall. The glacier breaks up into blocks as it flows over the edge. Blocks fall to the base, pack together, and continue flowing. This icefall, on Gibbs Island, Antarctica is typical. The bedrock is exposed through a large hole in the ice.
