Problem: Some rock formations in the path of a glacier are sculpted into small hills called roche moutonnee, or "sheepback" rock. Roche moutonnee are elongated, rounded, and asymmetrical bedrock knobs that can be produced by glacier erosion. They range in length from less than a meter to several hundred meters long. Roche moutonnee have a gentle slope on their up-glacier sides and a steep to vertical face on their down-glacier sides. The glacier abrades the smooth slope on the upstream side as it flows along, but tears loose and carries away rock from the downstream side via plucking.
How large are roche moutonnee?
The answer is the following: less than a meter to several hundred meters long
