The Lower Curtis Glacier in North Cascades National Park is a well-developed cirque glacier; if the glacier continues to retreat and melt away, a lake may form in the basin. Eventually, the hollow may become a large bowl shape in the side of the mountain, with the headwall being weathered by ice segregation, and as well as being eroded by ...
Lower Curtis Glacier is a cirque glacier in the North Cascades in the U.S. state of Washington. 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]
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 ...

Glaciers, typically forming in drainages on the sides of a mountain, develop bowl-shaped basins called cirques (sometimes called 'corries' – from Scottish Gaelic coire [kʰəɾə] (a bowl) – or cwm s). Cirque glaciers have rotational sliding that abrades the floor of the basin more than walls and that causes the bowl shape to form.
Cross section of a cirque glacier showing the randkluft. A randkluft (from the German for marginal cleft/crevasse) or rimaye (from the same French IPA:) is the headwall gap between a glacier or snowfield and the adjacent rock face at the back of the cirque [1] or, more loosely, between the rock face and the side of the glacier.
A cirque is an amphitheatre-like valley formed at the head of a glacier by erosion. ... Cirque de Cilaos; Cirque glacier; Cirque of the Unclimbables; L. Lassen Peak; P.
