The outcrop of more resistant rock is left protruding from the land and acts as a barrier to partly protect the less resistant rock down valley – resulting in a sloping tail. In the case of an upland glacial landscape, such as the Lake District, the dominant process at work were those of glacial erosion, transport and deposition.

What might the name mean when translated into English? Fig. Between ten and twenty metres in length and four metres high, roche moutonnée are resistant areas of bed rock formed as a glacier abrades the surface of the rock, carving it into a gentle upstream slope (known as the stoss slope), therefore creating a smooth convex shape as the ice travels over it (with a few polished striations and truncated end).
