frost mound
A conical mound on a land surface, caused by the freezing of water in the ground. It is a product of frost heaving, but is unusual in that it requires a great concentration of water in a relatively small subsurface volume. Usually a frost mound is of seasonal duration. Compare pingo, earth hummock, ground ice; see frost blister.
