This geological landform is a long, narrow inlet with steep sides or cliffs, created in a valley carved by glacial

activity

A process of glacial erosion by which blocks of rock are loosened,

detached, and borne away from bedrock by the freezing of water in

fissures

A deep, steep-walled recess in a mountain, caused by glacial erosion

A small, curved scar made by vibratory chipping of a bedrock surface by rock

fragments carried in the base of a glacier. Each mark is roughly

transverse to the direction of flow, and either convex ("lunate") or

concave ("crescentic") toward the direction from which the ice moved.

An Icelandic word meaning an outburst flooding from a glacial ice dam breakage or intense melt, as by

volcanic activity.

All processes by which snow, ice, or water in any form are lost from a

glacier

The percent of the incoming radiation that is reflected by a natural surface

such as the ground, ice, snow, water.

Incoming solar radiation.  Short wavelength radiation - a major

component of a glacier's energy balance.

A transition form between snow and glacial ice resulting from a

summer's consolidation, metamorphosis, and melt/refreeze.

A glacial lake in northwest Montana (USA) during Pleistocene times which

was formed by an ice dam of the Cordilleran ice sheet; this dam broke

periodically, flooding a portion of current-day northern Idaho and

Washington

Multiple scratches or minute lines, generally parallel but occasionally cross-cutting, inscribed on a rock

surface by a geologic agent. Common indicators of (at least the latest)

direction of glacier flow.

A crack in a glacier caused by rapid extension.

A long period of time (10,000+ years) characterized by climatic conditions

associated with minimum glacial extent

 Forms when an isolated block of ice persists in a ground moraine,

outwash plain, or valley floor after a glacier retreats; as the block melts, it leaves behind a steep-sided hole that

is filled with water

 A French word meaning a shaft by which supraglacial meltwater enters a

glacier to become englacial or subglacial

An unsorted, not stratified mixture of fine and coarse rock debris deposited

by a glacier

All processes that add snow or ice to a glacier or to floating ice or snow

cover: snow fall, avalanching, wind transport, refreezing...

A deposit, composed largely of material sorted by moving water, formed in

direct contact with glacier ice

Unconsolidated, wind deposited sediment composed largely of silt-

sized quartz particles (0.015-0.05 mm diameter) and showing little or no

stratification. It occurs widely in the central USA, northern Europe,

Russia, China, and Argentina.  In all but China, it is evidently derived

largely from reworked glacial outwash deposits.

The French equivalent of firn (which is German)

A body of ice showing evidence of movement as reported by the presence of an ice flowline,

crevasses, and recent geologic evidence

 Any glacier in a mountain range which is dominantly confined by the

surrounding topography. It usually originates in a cirque and may flow

down into a valley previously carved by a stream

A type of flow in which the surface, bed, and internal flow vectors are all parallel to one another, thus there is

no mixing.

A sinuously curving, narrow deposit of coarse gravel that forms along a

meltwater stream channel, developing in a tunnel within or

beneath the glacier. The ice-contact margins of this are often slumped and

mixed with till.

Inuktitut word for an area that is unglaciated, but surrounded by ice.

This type of valley is usually created by glaciers.

A plain of glaciofluvial deposits of stratified drift from meltwater-fed, braided, and overloaded streams

beyond a glacier’s morainal deposits.

An accumulation of boulders, stones, or other debris carried and deposited by

a glacier.

An elongated hill or ridge of glacial drift

Lakes formed in closed basins as a result of climates which also

encouraged glaciation: globally colder and locally wetter
