Pyramidal peak

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.

Cirque glaciers have rotational sliding that abrades the floor of the basin more than walls and that causes the bowl shape to form.

As cirques are formed by glaciation in an alpine environment, the headwall and ridges between parallel glaciers called arêtes become more steep and defined.

[citation needed] When three or more of these cirques converge on a central point, they create a pyramid-shaped peak with steep walls.

These horns are a common shape for mountain tops in highly glaciated areas.
