==Etymology==
An icefall is a portion of some glaciers characterized by rapid flow and a chaotic crevassed surface. Perhaps the most conspicuous consequence of glacier flow, icefalls occur where the glacier bed steepens and/or narrows. The term icefall is formed by analogy with the word waterfall, a similar, but much higher speed, flow phenomenon.
