Roche Moutonée A roche moutonée is a glacial landscape feature produced as an advancing glacier slides over a hill of surface bedrock. As the glacier advances up the side of the hill, the surface bedrock is abraded and smoothed by rock fragments carried within the base of …

"mountains" that lie in the direction of glacial flow Name 3 glacial depositional landforms that are left behind by RETREATING glaciers. ---The plastic ice mass follows the small-scale roughness of the base and therefore the directions of striae differ from place to place, even on the same roche moutonnee. Rock surfaces which dip less than 300 have only a small effect on the general direction of ice movement. If the dip is more than 500 it changes direction markedly (Fig.

The smoothed (up-glacier) face is on the north side, and the rough or plucked face is on the south side. The latter is much steeper, as we can see -- because this is the face from which blocks of rock have been dragged away. A roche moutonnée is a geomorphic feature of mesoscale (1m to 1km of length), in the form of a boss or rocky elevation, of asymmetrical profile, having a less inclined, glacially polished and eroded, upglacier (stoss) side and a more irregular, steeper downglacier (lee) face made by plucking or quarrying of rock fragments from the basement. Jagged, rocky side of the roche moutonnee. These aspects of a roche moutonnee are very easy to see in Mack Park, Salem.

Roche moutonnée. Some rock formations in the path of a glacier are sculpted into small hills called roche moutonnée, or “sheepback” rock. Roche moutonnée are elongated, rounded, and asymmetrical bedrock knobs can be produced by glacier erosion. They range in length from less than a meter to several hundred meters long. Roche moutonnée
