Earth hummocks of cryogenic origin Cryogenic earth hummocks on Mount Kenya Cryogenic earth hummocks go by various names; in North America they are known as earth hummocks; the Icelandic term þúfa/thúfa (pl. þúfur/thúfur ) is also used to describe them in Greenland and Iceland, and the Finnish term pounu (pl. pounut ) in Fennoscandia. These cold climate landforms appear in regions of permafrost and seasonally frozen ground. They usually develop in fine-grained soils with light to moderate vegetation in areas of low relief where there is adequate moisture to fuel cryogenic processes.Davis, Neil. (2001). Permafrost: A Guide to Frozen Ground in Transition. Fairbanks, Alaska: University of Alaska Press. p. 133, 137-40, 146, 175-76.
