They also abrade rock and debris from their substrate to create landforms such as cirques and moraines.
Many glacial cirques contain tarns dammed by either till (debris) or a bedrock threshold.
All bodies of ice located in these cirques are separated by artes.
When three or more cirques erode toward one another, a pyramidal peak is created.
The method of erosion of the headwall lying between the surface of the glacier and the cirques floor has been attributed to freeze-thaw mechanisms.
As the snowline continues to rise, new cirques would continue to form the steps of the cyclopean stairs.
The body of this batholith has been deeply cut by glacial cirques and canyons.
The east face of the feature is indented by twin cirques that resemble eyes.
