About this map

Bearmouth occupies a strategic position along the Clark Fork river, where the valley floor meets the rising terrain of the Lolo National Forest. The landscape is defined by a dense network of gulches and ridges, including Harvey Ridge and the distinct drainages of Felan Gulch, Packer Gulch, and Snyder Gulch. Transport through this corridor is well-documented, showing the proximity of the historic Mullan Rd and various frontage routes that service the area's steep topography.

Water sources like Bearmouth Spring and Antelope Cr are key features of the local geography, feeding into the larger river system. The map details numerous smaller canyons such as Mulkey Gulch and Garden Gulch to the east, while Welch Gulch and McKnight Gulch mark the southern reaches. This modern survey reflects the enduring influence of the river and mountain passes on the settlement patterns and road networks of Granite County.
