Clark Fork river valley serves as the primary corridor for transportation and settlement in this 1960 Montana survey. The town of Superior occupies a narrow shelf along the river, flanked by the competing lines of the Northern Pacific and the Chicago Milwaukee St Paul and Pacific railroads. This infrastructure supported a regional economy once heavily dependent on timber and mineral extraction, evidenced by the Iron Mountain Mine and various Old Mountain Mines situated deep in the surrounding canyons.
