I was looking at the 1984 WMNF map and found an Osseo route(picture linked below) that starts at a similar location to the current Osseo trail, but goes over Whaleback, meeting and taking the old Osseo. I know the new Osseo was built in the 80s, but did it go through a pretty quick and substantial reroute after being built? The map doesn't have much detail, does anyone know more about the route? Did it hit any sweet slides on the way up to Whaleback?
