Bob Marshall Wilderness

The Bob Marshall Wilderness is a congressionally designated wilderness area in western Montana, named for Bob Marshall, a forester and co-founder of The Wilderness Society who spent the 1930s pushing the US Forest Service to protect large roadless areas by regulation. Formally designated under the Wilderness Act in 1964, it extends roughly sixty miles along the Continental Divide and covers just over one million acres of forest, alpine grassland and the limestone reef known as the Chinese Wall. Together with the adjoining Great Bear and Scapegoat wilderness areas, it forms one of the largest contiguous roadless wildlands in the lower forty-eight United States.
