About this map

Patterson sits at the base of the high country in the late 1980s, where the Pahsimeroi Valley meets the steep slopes of the Challis National Forest. This landscape is defined by its industrial geography, most notably the extensive Patterson Tailings and a Mine located along the drainage of Patterson Creek. The drainage patterns here are complex, with several watercourses like Falls Creek, Mahogany Creek, and the East Fork cutting through the terrain to feed the valley floor.

Evidence of historical resource extraction is prominent, as indicated by the presence of a Mine and tailings piles near the primary settlement. The road network is sparse, relying on 4wd tracks to navigate the backcountry toward Mill Creek. This 1989 provisional edition captures a specific moment in Lemhi County history when mining operations and federal forest lands dictated the local economy and land use.
