ice piedmont

ice covering a costal strip of low-lying land backed by mountains; the surface of an ice piedmont slopes gently seawards and may be anything from 1 to 50 kilometers (0.6 to 31 miles) wide, fringing long stretches of coastline with ice cliffs; ice piedmonts frequently merge into ice shelves; a very narrow ice piedmont may be called an ice fringe.

ice limit

the average position of the ice edge in any given month or period based on observations over a number of years.

Ice gland

A column of ice in the granular snow at the top of a glacier.

ice fringe

a very narrow ice piedmont, extending less than about 1 km inland from the sea.

ice divide

the boundary separating opposing flow directions of ice on a glacier or ice sheet.

ice covered

land overlaid at present by a glacier is said to be covered; the alternative term glacierized has not found general favour.

ice core

a core sample drilled from the accumulation of snow and ice over many years that have recrystallized and have trapped air bubbles from previous time periods, the composition of which can be used to reconstruct past climates and climate change; typically removed from an ice sheet (Antarctica and Greenland) or from high mountain glaciers elsewhere.


the solid crystalline form of water.

ice cave

a natural bedrock cave that contains year-round ice.

ice cap

a dome-shaped mass of glacier ice that spreads out in all directions; an ice cap is usually larger than an icefield but less than 50,000 square-kilometers (12 million acres).
