The Bob Marshall Wilderness Complex is the largest wilderness area in the Lower 48 states, covering 1.5 million acres, or about 2,400 square miles. I hate to keep picking on Rhode Island for these comparisons, but the Bob, as it is usually called, is more than twice the size of that state.
The complex includes the Bob Marshall Wilderness proper, and the Great Bear and Scapegoat wilderness areas. It abuts Glacier National Park, creating a huge area of relatively untouched country extending nearly half the width of Montana from the Canadian border. Marshall himself was one of the earliest advocates of wilderness for its own sake in the U.S., and the wild lands that bear his name were among the areas designated by the federal Wilderness Act of 1964. The Great Bear and Scapegoat areas were set aside in the 1970s.
Just south of Glacier National Park, the complex occupies nearly the entire territory that lies between the boundaries of U.S. 2 to the north, Mont. 83 to the west, Mont. 200 to the south, and U.S. highways 287 and 89 to the east. Access points along these roads occur infrequently and are poorly marked, so keep your eyes peeled.
The wilderness area has become very popular with hikers and horse-packers over the years, leading to a curious pattern of trail deterioration. Federal budget austerity allows the U.S. Forest Service little funding for trail maintenance, and while heavy traffic on the most popular trails has led to their erosion, many of the secondary trails have virtually disappeared. Quite a few trails that are marked on topographical maps of the area are faint or nonexistent on the ground. You should know fundamental trail-finding and direction skills -- how to read a topo map -- in case a trail dies out or is covered by snowbanks.
