Bob Marshall Wilderness, Nature reserve in Western Montana, United States
Bob Marshall Wilderness is a protected area in western Montana that follows the Continental Divide through mountain ranges and valleys rising from 4,000 to 9,000 feet. The reserve spans six counties and covers roughly 1.5 million acres of forest, meadows, and ridgelines without roads or permanent structures.
Several smaller primitive areas joined together in 1940 to form a single protected zone. The Wilderness Act of 1964 gave the territory its formal status and protection from road building or commercial development.
Locals and Forest Service staff call the area "The Bob". Its name honours Bob Marshall (1901–1939), a Forest Service forester and co-founder of The Wilderness Society who pushed through roadless-area regulations in the 1930s. The five ranger districts keep 1,856 miles of trail open to foot and stock use only, so horses remain a normal way to travel here.
