1955 Map of Garnet Mountain

About this map

Gallatin National Forest dominates this mid-century landscape, centered on the canyon carved by the Gallatin River. The river corridor serves as the primary artery for settlement and industry, home to the Karst Ranch, its associated Karst Power Plant, and the Blanchard Sawmill. These sites reflect a mountain economy transitioning from raw resource extraction to early recreational development, evidenced by the cluster of Cascade Creek Summer Homes and various camps like Shady Rest Camp.
