Sign 2. By the striations.
The stripes you see in the bedrock are called striations. These were formed when the ice sheet covered the area about 10.000 years ago. Rocks frozen into the base of the glacier abraded the bedrock like a giant piece of sandpaper. Striations are thus traces of glacier movement, and while they do not indicate the directions of the movement, we must find other landforms, so called cresentic gouges and roche mountenèe, to reveal that to us. Can you find them in the area?
