Hummock

A hummock is a small knoll or mound above ground. They are typically less than 15 meters in height and tend to appear in groups or fields. It is difficult to make generalizations about hummocks because of the diversity in their morphology and sedimentology. An extremely irregular surface may be called hummocky.

An ice hummock is a boss or rounded knoll of ice rising above the general level of an ice-field. Hummocky ice is caused by slow and unequal pressure in the main body of the packed ice, and by unequal structure and temperature at a later period.

Swamp Hummocks

Swamp Hummocks are mounds typically initiated as fallen trunks or branches covered with moss and rising above the swamp floor. The low-lying areas between hummocks are called hollows. A related term, used in the Southeastern United States, is "hammock".

Earth hummocks of cryogenic origin

Cryogenic earth hummocks go by many different names; in North America they are earth hummocks; thúfur in Greenland and Iceland; and pounus 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.
