A roche moutonnée is a glacial landform created by the differential erosion caused by a glacier. The upstream side is typically smoother and polished while the downstream side is plucked and jagged. Plucking occurs when the glacier freezes onto the rock and when the ice moves, it plucks or breaks the rock off.
