Great Bear Wilderness

The Great Bear Wilderness was congressionally designated as a Wilderness area in 1978 with a total of 286,700 acres. The Great Bear Wilderness extends roughly 36 miles and at its widest point is about 34 miles across. Elevations range from 4000 feet on the Middle Fork to 8,700 feet on Great Northern Mountain. The Great Bear forms a critical ecological link with Glacier National Park located just across U.S. Highway 2 to the north. The Great Bear completes the habitat protection for the most significant grizzly bear range in the lower 48 states.
