A cirque (French:; from the Latin word circus) is an amphitheatre-like valley formed by glacial erosion. Alternative names for this landform are corrie (from Scottish Gaelic : coire , meaning a pot or cauldron ) [ 1 ] and cwm ( Welsh for 'valley'; pronounced [kʊm] ).
Cirque – An amphitheatre-like valley formed by glacial erosion; Cliff – Tall, near vertical rock face; Chink, regional term in Central Asia for steep chalk and limestone escarpments and cliffs of height up to 350m, often around flat-top elevations; Cryoplanation terrace – Formation of plains, terraces and pediments in periglacial environments
A cirque glacier is formed in a cirque, a bowl-shaped depression on the side of or near mountains. Snow and ice accumulation in corries often occurs as the result of avalanching from higher surrounding slopes. If a cirque glacier advances far enough, it may become a valley glacier. Additionally, if a valley glacier retreats enough that it is ...
A cirque stairway or sequence of cirque steps is a stepped succession of glacially eroded rock basins. [1] Their individual formation is that of a cirque . These steps are arranged one above and behind the other at different heights in the terrain and caused by the same morphodynamic processes, albeit resulting in different landform shapes ...
Cirque glaciers are glaciers that appear in bowl-shaped valley hollows. [4] [12] Snow easily settles in the topographic structure; it is turned to ice as more snow falls and is subsequently compressed. [12] When the glacier melts, a cirque structure is left in its place. [4] Examples include: Lower Curtis Glacier, Washington, United States

A bergschrund (from the German for mountain cleft) is a crevasse that forms where moving glacier ice separates from the stagnant ice or firn above. [1]
