The Clark Fork river valley serves as the central artery of this region, where the historical Mullan Rd and Old Hwy 10A track the corridor between the Garnet Range and the surrounding foothills. The settlement of Drummond acts as a focal point near the confluence with Flint Creek, surrounded by smaller locales like New Chicago, Bradman, and Ozan. This area is defined by its transition from the valley floor to high points such as King Mtn, with numerous drainages like Spring Gulch and Lyon Gulch cutting through the terrain.
