Roche moutonnée near Myot Hill, Scotland In glaciology, a roche moutonnée (or sheepback) is a rock formation created by the passing of a glacier.The passage of glacial ice over underlying bedrock often results in asymmetric erosional forms as a result of abrasion on the "stoss" (upstream) side of the rock, and plucking (i.e. pieces cracked off) on the "lee" (downstream) side.
Erosional landforms. As the glaciers expand, due to their accumulating weight of snow and ice they crush, abrade, and scour surfaces such as rocks and bedrock.The resulting erosional landforms include striations, cirques, glacial horns, arêtes, trim lines, U-shaped valleys, roches moutonnées, overdeepenings and hanging valleys.
Ronas Voe has been named Shetland's "only true fjord". [27] The cliffs of Ronas Voe are the result of ancient glaciers cutting through a ridge of raised land. [28] The cliffs at the Brough are an example of a roche moutonnée, in which the exposed rock has been sculpted by the passing glacier creating a smooth surface up-ice, and a rough exterior on the rock down-ice.

Mt. Susitna is a roche moutonnée, a landform created when a glacier flows over a resistant, topographically high, bedrock body, creating a smooth-sided and teardrop shaped feature aligned with the direction of ice flow. [5] The Anchorage bowl topography has been influenced by 5-7 glaciations.
