About this map

The Bob Marshall Wilderness and Lewis and Clark National Forest dominate this mid-century landscape in the Montana backcountry. The terrain is defined by the convergence of the North Fork and South Fork of Glenn Creek, along with the prominent North Fork Sun River. Mapping from the 1950s shows a wilderness managed through a network of Pack Trails, connecting remote outposts like the Cabin Creek Guard Station.

Evidence of local wildlife and geology appears in labels like Sulphur Creek Lick and the numerous peaks including Sheep Mtn and White Ridge. The map illustrates the specialized land use of the era, specifically within the Sun River State Game Preserve, where the boundary crosses Two Shacks Flat. This survey provides a record of the primitive transportation routes used by forest rangers and early recreationalists before modern infrastructure altered mountain access.
