In glaciology, a roche moutonnée (or sheepback) is a rock formation created by the passing of a glacier. The passage of glacier 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 on the `lee` (downstream) side. These erosional features are see...
