Waterton-Glacier International Peace Park is the ecological heart of the Crown of the Continent ecosystem. Here, a bighorn sheep stands near the boundary between Glacier National Park and the adjacent Blackfeet tribal roadless areas. While they are well-protected within the park, bighorn sheep often cross boundaries invisible to them, and roam into the Badger-Two Medicine Roadless Area, or onto private lands. For the health of these herds, it is important that public land managers and private landowners collaborate as stewards of America’s great inheritance.
