Definition: Potholes formed at the bottom of glaciers through erosion caused by sand and gravel in melt-water; melt-water seeps through crevasses in the glaciers, sometimes forming whirlpools; at the bottom of the glacier, the water is under very high pressure, leading to erosion of underlying rocks.  NSIDCCryosphere 

A deep and more or less vertical hole in a glacier. Glacier pot-holes drain away surface melt-water.  SPRI
