The crescentic gouges you see here were formed when rubble materials were frozen into the base of the glacier, and pressed forcefully against the bedrock. When the pressure became great enough, the rock cracked into splinters along a crescent arc, and a crescentic gouge was formed. The part of the sickle which grades the most steeply into the rock is directed toward the movement of the ice.

Question: In what direction did the ice move in this area?
