Alpine Glaciation Features

Continental Glaciation Features


Cirque - bowl-shaped depression on a high mountain slope, formed by a cirque glacier


Drumlins - streamlined hill, asymmetrical in lengthwise profile with steep slope facing the direction from which the ice came


Horn Arete - steep-sided, pyramid-shaped peak produced by headward erosion of several cirques


Esker - long, narrow, sinuous ridge of drift deposited by meltwater streams flowing under glacial ice


Glaical Trough - u-shaped, steep-walled, glaciated valley formed by the scouring action of a valley glacier


Ground Moraine - sheetlike layer (blanket) of till left on the landscape by a receding glacier

End/Terminal Moraine - ridge of till that forms at the farthest advance of a glacier


Lateral Moraine - Ridge of till formed from melting ice and mass wasting at the side of a valley glacier

Medial Moraine - ridge of till either in transit or deposited along the boundary between two tributary glaicers that have merged to forma larger valley glacier
