For the Love of Geography: Arêtes

We continue our study on mountain glacial landforms with the arête.

An arête is formed by two glaciers scouring away rock on two sides of a mountain. The result is a thin ridge of rock which separates two U-Shaped valleys. Weathering further erodes the rock thus shaping and sharpening the feature. Arêtes can also be formed when two cirques erode.
