Roche moutonnée. A roche moutonnée is formed where glacial ice flows over a rock outcrop, abrades the upstream side of the outcrop, and plucks the downstream side, creating an asymmetrical hill. The blunt end points in the direction of the glacier’s movement. This roche moutonnée near the town of Wanaka, on the South Island of New Zealand, is about 240 m (800 ft) high.(© Yvon Maurice)
