About this map

The confluence of the Blackfoot R and the Clark Fork serves as the industrial and transit anchor for this Missoula County corridor. Heavily influenced by the lumber and transport industries of the mid-1960s, the map illustrates a landscape defined by parallel rail lines: the Northern Pacific and the Chicago Milwaukee St Paul and Pacific. These tracks flank the river and highway, connecting the timber-rich reaches of the Lolo National Forest to processing centers.

Settlements like Bonner and Piltzville cluster near the river bends, where topography allowed for early development and milling operations. Further southeast, Turah and the McQuarrie Spur highlight the importance of rail sidings and Gravel Pit extractions in the local economy. Beyond the valley floor, the terrain rises sharply toward Bonner Mountain and Moccasin Ridge, where various gulches and creeks like Bear Gulch drain into the Clark Fork basin.
