Hummock

From Wikipedia, the free encyclopedia

Hummock (of uncertain derivation; cf. hump or hillock), a boss or rounded knoll of ice rising above the general level of an ice-field, making sledge travelling in the Arctic and Antarctic region extremely difficult and unpleasant.

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.

An earlier use of this term also refers to lumpy terrain; or land that has an irregular shape; or a fertile, wooded area that is at a slightly higher elevation (less than 3 m or so) than nearby marshes.
