I would bet that this pic is taken at what is currently the location of Ryden's Store just south of the border, since I don't see Pigeon River anywhere in sight. The border runs right down the middle of the river and has been demarked since the signing of the Treaty of Paris ending the American Revolution. So the line is right in the center of the bridge. Ryden's has been there for years, just is a lot larger than in this old picture. Still a very scenic drive up MN 61 and the North Shore to the border. Would be great for touring if the traffic was lighter.
