In Greenland, an insular hill or mountain surrounded by an ice sheet.
inuit-derived word describing a mountain completely surrounded by an ice cap.
A nonglaciated area surrounded by glaciers, often a mountain peak taller than the surrounding glaciers.
Geomorphological feature - A peak poking out from an ice cap.
Islands standing out in a 'sea of ice' during periods of glaciation and in which species may have persisted.
Islands of mountain tops that pertrude above glacier.
A rocky crag or small mountain projecting from and surrounded by a glacier or ice sheet.
(Inuktitut) An area that is unglaciated, but surrounded by ice.
a large piece of rock sticking up through an ice sheet
a mountain or hill surrounded completely by glacial ice
an area of land, usually a mountain top, that remained free of ice during the ice age and many believe that some of the relic species of plants survived the period of the ice ages on these
an isolated mountain peak or hill rising above the surrounding glacial ice
An exposed hill or mountain completely surrounded by glacial ice.
A mountain peak completely surrounded by glacial ice.
The tip of a mountain that appears above the Antarctic icecap
any mountain poking through the ice blanket
An isolated peak of bedrock that sticks above the surface of an ice sheet. They are the peaks of hills and mountains standing above the ice sheet which flows around them. They offer important information about ice covered regions as they provide a sample of the rocks that lie under the ice.
A peak of resistant rock of sufficient height that it rises above the ice sheet like an island and thus escapes the effects of glaciation.
Eskimo term refering to mountains or lands that protrude through an ice sheet.
An isolated hill or peak which projects through the surface of a glacier and is completely surrounded by ice or snow. Ogives 1 Ogives 2 are arc-shaped features occasionally found across the glacier surface below icefalls. They may be ridges and swales in the ice or bands of darker or lighter ice. One theory of their formation suggests that the ice is stretched and sometimes dirtied when exposed in the icefall during the high velocities of summer; it is compressed during the winter so that bands of different ice thickness form.
A nunatak (plural: nunataks) is a mountain top that is not covered by land ice (see glaciation and ice age), and protrudes out of a surrounding glacier. The wildlife on a nunatak can be isolated by the glacier, just like an island is in the ocean. Nunataks are generally angular and jagged because of freeze-thaw weathering, and can be seen to contrast strongly with the softer contours of the glacially eroded land below if the glacier retreats.
