Frost mound
From Glossary of Meteorology
frost mound
(Also called ice mound, ground ice 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.
