WebLower Curtis Glacier is a corrie glacier in the North Cascades in the US state of Washington. 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 ...

WebFeb 9, 2018 · Cirques are bowl-shaped, amphitheater-like depressions that glaciers carve into mountains and valley sidewalls at high elevations. Often, the glaciers flow up and over the lip of the cirque as gravity drives them downslope. Lakes (called tarns) often occupy these depressions once the glaciers retreat.
Alpine Glaciers: Formation, Types, Location and Facts
WebCirque glacier: Bowl like hollow structures are called cirque glaciers. They are formed inside the mountains and tend to move towards the valley. Ice Aprons: Small steep glaciers clinging to the high mountains are called ice aprons. They are an accumulation of ice masses and snow that stick towards the topography of the glacierized basin.

WebA cirque glacier is a small glacier that occupies a bowl-shaped basin at the head of a mountain valley. Cirque glaciers are usually the remnants of much larger valley glaciers. Andrews, Tyndall, and Rowe are all good examples of small cirque glaciers.
Cirque glaciers | SpringerLink
WebCirque glaciers (see Hobbs, 1911; Matthes, 1942) occur in mountainside niches of distinctive shape, called cirques (q.v.). Some cirque glaciers are closely adjusted in size to the cirques they occupy, while others become enlarged and overspill the cirque threshold giving rise to a valley glacier.
