About this map

Clark Fork canyon serves as the primary corridor for industry and transit in this late-1950s survey of Granite County. The narrow valley floor is tightly packed with competing infrastructure, most notably the dual rail lines of the Northern Pacific and the Chicago Milwaukee St Paul and Pacific. The tiny settlement of Bearmouth sits at a critical junction where trails and roads begin their ascent into the surrounding high country.

Away from the river, the landscape transitions into the steep slopes of the Lolo National Forest and Deerlodge National Forest. Remote outposts like Griffith Cabin and Harvey Cabin are connected by an intricate network of paths, including the Pack Trail and Pole Ridge Trail. Evidence of the region's extractive history is visible in the dredge tailings along the southern creeks, while summits like Mt Baldy and Sugarloaf define the horizon.
