The Bitterroot Range forms the backbone of this topographic study, defining the high-altitude boundary between Idaho and Montana. This high ridgeline, labeled simply as the State Line, separates Shoshone County and Mineral Co, creating a sharp divide between the St. Joe National Forest to the southwest and the Lolo National Forest to the northeast. Elevation peaks at landmarks like Torino Peak and Sunset Peak, while the drainage basins of the N Fork Little Joe Creek and Torino Creek carve deep gulches into the mountain faces.
