The Blackfoot River carves a deep valley through this portion of the Lolo National Forest in Missoula County. The settlement at McNamara and the McNamara Bridge serve as focal points for the local transport network, where Johnsrud Park Rd and Gold Creek Rd navigate the steep, forested slopes. The terrain is defined by prominent peaks like Sunflower Mtn and Diamond Mtn, with numerous drainages such as Union Cr and W Fork Gold Cr feeding into the main river system. Small clearings and flatlands like Sheep Flats and Camas Prairie offer brief respites from the dense timber of the national forest. Local landmarks such as Johnsrud Park and the small community of Twin Creeks reflect the long-standing human presence in this timber and river corridor.
