The Clark Fork river corridor defines the southern portion of this region, serving as the primary artery for both transportation and early settlement. At the close of the 1950s, the rail infrastructure of the Chicago Milwaukee St Paul and Pacific and the Northern Pacific railroads remains prominent, connecting the small communities of Tarkio, Martel, and Rivulet. These settlements are closely tied to the river and the surrounding Lolo National Forest, where the landscape is carved by numerous drainages like Ninemile Creek and Cedar Creek.
