Nunatak

[6] Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named.

While some are isolated, they can also form dense clusters, such as Queen Louise Land in Greenland.

[7] Nunataks are generally angular and jagged, hampering the formation of glacial ice on their tops, although snow can accumulate on them.

This can contrast strongly with the softer contours of the glacially eroded land after a glacier retreats.

Lifeforms on nunataks are often isolated by the surrounding ice or glacier, providing unique habitats.
