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
