Also, located around the reservoir is the Hugh Glass Lakeside Use Area, named for the mountain man, Hugh Glass, which is also operated by the Game, Fish, and Parks as a free campground, boat launch and picnic area.[3] A historical monument to Hugh Glass stands near the site of his mauling on the southern shore of Shadehill Reservoir, at the forks of the Grand River.
