About this map

Marias Pass serves as a critical geographic pivot point on this 2020 survey, marking the continental divide where Glacier National Park, Lewis & Clark National Forest, and Flathead National Forest converge. The settlement of Summit and the nearby Theodore Roosevelt Pass highlight the historic importance of this corridor for transcontinental transit through the Northern Rockies. The landscape is defined by the high peaks of the Sawtooth Range and the headwaters of the Two Medicine River, which flows eastward away from the divide.

Modern recreation is evidenced by the extensive path of the Continental Divide National Scenic Trail as it winds past Three Bears Lake and north toward False Summit. The map details a complex network of seasonal routes including Skyland Rd and specialized paths like the Skyland Mule Sm (Snow) trail. These labels reflect a wilderness area managed for multiple uses, from the protection of Skeleton Mtn to the managed timber and range lands of the surrounding national forests.
