I might have found the remains of a shipwreck on google earth pro some of it washed up on the beach and hill side do to waves being so big and massive it could be the top of a ww1 submarine probably German but I am not sure. Google view location of the parts 46°47'48.28" N 92°04'55.20" W and the main walk way assembly support I think it is possibly 46°47'40.47" N 92°04'50.27" W. Screen shots of the white marks and the ship remains on the beach to.
