1959 Map of Bearmouth

About this map

The Clark Fork river valley serves as the primary corridor for transportation and industry in this 1950s survey of Granite County. Following the river's path, the Northern Pacific and Chicago Milwaukee St Paul and Pacific railroads parallel the historic Mullan Road, connecting small settlements like Bearmouth, Nimrod, and Byrne. Evidence of local mineral extraction is visible in the dredge tailings found along the southern watercourses, while the high country is defined by the John Long Mountains and Harvey Ridge.
