The arête is a thin ridge of rock that is left separating the two valleys Arêtes can also form when two glacial cirques erode head wards towards one another, although frequently this results in a saddle-shaped pass, called a col. The edge is then sharpened by freeze-thaw weathering. Where three or more cirques meet, a pyramidal peak is created. - (a famous example is the 'Matterhorn').
