1963 Map of Boulder Lakes

About this map

Kootenai National Forest dominates this mid-century terrain in Lincoln County, characterized by a complex network of high peaks and drainage basins. The landscape is defined by the convergence of several major water systems, including Big Creek and the West Fork Basin Creek. High-altitude landmarks such as Purcell Summit and Boulder Mountain rise above the basin floors, where Boulder Lakes sits tucked below the ridgelines. Human presence in this section of the forest is minimal and centered on backcountry navigation, as evidenced by the Pack Trail routes and the lone Big Creek Cabin located near the southern watercourses. This map documents a period of remote forest management before modern road expansion, preserving the original routes used by rangers and early visitors to reach landmarks like Thirsty Mountain and the headwaters of Porcupine Creek.
