A nunatak (from Inuit nunataq) is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They often form natural pyramidal peaks. Isolated nunataks are also called glacial islands,[2] and smaller nunataks rounded by glacial action may be referred to as rognons.[3][4]
The word is of Greenlandic origin[5] and has been used in English since the 1870s.
