roche moutonnée   (rôsh' mt'n-ā', m'tô-nā')  Pronunciation Key 
An elongate mound of bedrock worn smooth and rounded by glacial abrasion. A roche moutonnée has a long axis parallel to the direction of glacial movement, a gently sloping, striated side facing the direction from which the glacier originated, and a steeper side facing the direction of glacial movement. The height, length, and width of roche moutonnées are on the order of a few meters (tens of feet).

roche moutonnee

glaciated bedrock surface, usually in the form of rounded knobs. The upstream side of a roche moutonnee has been subjected to glacial scouring that has produced a gentle, polished, and striated slope; the downstream side has been subjected to glacial plucking that has resulted in a steep, irregular, and jagged slope. The ridges dividing the upstream and downstream slopes are therefore perpendicular to the general flow direction of the former ice mass
