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 ...
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 ...
Iceberg Cirque. The Iceberg Cirque is a large cirque that has been carved out by glaciation.It is located in Glacier National Park in the U.S. state of Montana.It is near Iceberg Lake in the Many Glacier section of the park, and can be approached by a hike starting at the Many Glacier Hotel.
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]

Tarns are the result of small glaciers called cirque glaciers. Glacial cirques (or 'corries') form as hollows on mountainsides near the firn line.Eventually, the hollow in which a cirque glacier develops may become a large bowl shape in the side of the mountain, caused by weathering, by ice segregation, and as well as being eroded by plucking.
A pyramidal peak, sometimes called a glacial horn in extreme cases, is an angular, sharply pointed mountain peak which results from the cirque erosion due to multiple glaciers diverging from a central point. Pyramidal peaks are often examples of nunataks.
The Dove is a small cirque glacier or perennial snowfield located in Rocky Mountain National Park in the U.S. state of Colorado. [2] The Dove is on the north slope of Longs Peak and near The Keyhole , which is along a popular climbing route to the summit.
