glacier table

a rock that resides on a pedestal of ice; formed by differential ablation between the rock-covered ice and surrounding bare ice.
Talefre Glacier on Mont Blanc Massif in the European Alps sported a prominent glacier table when this undated photograph was taken. The rock protected the ice directly below it from melting, resulting in the characteristic pedestal that remains after the surrounding ice melts. For scale, note the...

glacier sole

the bottom of the ice of a glacier.

glacier snout

the lowest end of a glacier; also called glacier terminus or toe.
Glacier at the head of Canon Fiord, Ellesmere Island, Canada

glacier remainie

a glacier that is reconstructed or reconstituted out of other glacier material; usually formed by seracs falling from a hanging glacier, then re-adhering; also called reconstituted, reconstructed or regenerated glacier.

glacier pothole

potholes formed at the bottom of glaciers through erosion caused by sand and gravel in melt-water; melt-water seeps through crevasses in the glaciers, sometimes forming whirpools; at the bottom of the glacier, the water is under very high pressure, leading to erosion of underlying rocks.

glacier mill

a nearly vertical channel in ice that is formed by flowing water; usually found after a relatively flat section of glacier in a region of transverse crevasses.

glacier ice

well-bonded ice crystals compacted from snow with a bulk density greater than 860 kilograms per cubic-meter (55 pounds per cubic-foot).

glacier flour

a fine powder of silt- and clay-sized particles that a glacier creates as its rock-laden ice scrapes over bedrock; usually flushed out in meltwater streams and causes water to look powdery gray; lakes and oceans that fill with glacier flour may develop a banded appearance; also called rock flour.

glacier flood

a sudden outburst of water released by a glacier.

glacier fire

a phenomenon in which strong reflection of the sun on an icy surface causes a glacier to look like it is on fire.
