About this map

Clark Fork defines the western valley of this landscape, where the Superior Oliverville Rd connects the settlement of Oliverville to the surrounding timberlands of the Lolo National Forest. The topography is dominated by the steep drainages of the Ninemile Divide, with numerous gulches such as Idaho Gulch, Welch Gulch, and Shyrock Gulch feeding into the river system. This late-20th-century update reveals a landscape balanced between resource extraction and transportation infrastructure, evidenced by the Gravel Pits and the presence of a County Airport complete with an Airway Beacon positioned near the river's bend.

The boundary between Mineral and Missoula counties cuts across the high ridges, where streams like Ninemile Creek and Flat Creek begin their descent. The map illustrates the complex interface of public and private lands, showing how the Forest Service managed the area's transition from the high peaks of the divide down to the vital riparian corridor of the Clark Fork and its tributaries like Trout Creek.
