Bob Marshall Wilderness - Bob Marshall Wilderness Complex
Located in Northwestern Montana on both sides of the Continental Divide, this large complex includes three Wilderness areas: the Great Bear, the Scapegoat, and the Bob Marshall Wilderness. Together the Bob Marshall Wilderness Complex makes up an area of more than 1.5 million acres, the third largest in the lower 48 states. Grizzly bear, lynx, wolverine, deer, elk, gray wolf, moose, black bear, mountain lion, mountain goat, and mountain sheep roam about these rugged ridge tops, gently sloping alpine meadows, thickly forested river bottoms and open grass parks. Across this continuous landscape over 1700 miles of trail provide challenges and experiences to satisfy visitors with a wide range of skills.
The Bob Marshall Wilderness was named after forester, wilderness preservation pioneer and Wilderness Society cofounder: Bob Marshall. The region was set aside as the South Fork, Pentagon and Sun River Primitive Areas between the years of 1931-1934 then, congressionally designated as Wilderness in 1964. In 1978, additional lands were designated bringing the total to 1,009,356 acres.
The Continental Divide separates the Flathead and Sun River drainages with elevations ranging from 4,000 feet to more than 9,000 feet. A huge escarpment called the Chinese Wall, a part of the Divide, highlights the Bob's vast untrammeled beauty, with an average height of more than 1,000 feet and a length of 22 miles. The Chinese Wall extends into the Scapegoat Wilderness, which lies to the south, while the Great Bear Wilderness shares the border to the north.
