| arête (ə-rāt') Pronunciation Key
A sharp, narrow ridge or spur commonly found above the snow line in mountainous areas that have been sculpted by glaciers. Arêtes form as the result of the continued backward erosion of adjoining cirques. |
arete
(French: "ridge"), in geology, a sharp-crested serrate ridge separating the heads of opposing valleys (cirques) that formerly were occupied by Alpine glaciers. It has steep sides formed by the collapse of unsupported rock, undercut by continual freezing and thawing (glacial sapping; see cirque). Two opposing glaciers meeting at an arete will carve a low, smooth gap, or col. An arete may culminate in a high triangular peak or horn (such as the Matterhorn) formed by three or more glaciers eroding toward each other
