2017 Map of Bearmouth

About this map

Bearmouth occupies a strategic position along the Clark Fork river, where transportation corridors have carved through the Montana landscape for generations. This 2017 survey illustrates the modern alignment of Interstate 90 and the Bearmouth RR Access Rd alongside the historic path of Mullan Rd. The surrounding terrain is defined by a dense network of gulches, including Felan Gulch, Packer Gulch, and Snyder Gulch, which drain from the high ridges into the river valley. To the southwest, the Lolo National Forest boundary marks a transition into protected timberlands. Local infrastructure is anchored by ranching and access roads like Bear Gulch Rd and Cow Creek Rd, while features like Bearmouth Spring and Harvey Ridge provide specific landmarks for those studying the physical geography and land use of Granite County.
