We ate breakfast and packed up fairly early. Started heading back the way we came and when we got to the the bottom of Friday Bay the wind picked up. It wasn't bad until we got back onto the bigger lakes like Gun, Boot and Fourtown. We had water pouring in the front and back of canoe on Fourtown. That was not fun, but we made it out with no incidents. Had a great trip! 

Has anyone else seen this? Its on the American side of Big current north of the campsite on a rock wall. What is it???
