1972 Map of Banner Summit

About this map

The high Sawtooth Range landscape of central Idaho is defined here by the crossing of the Custer and Boise county lines at the prominent Banner Summit. This high-altitude terrain serves as a drainage divide where headwaters like the North Fork Boise River and Marsh Creek begin their descent. The presence of several high-mountain basins, including Bull Trout Lake, Newman Lake, and Dutch Lake, highlights the alpine character of the region during the early 1970s. Historical land use is evident in the cluster of Mines located on the slopes of Copper Mountain, suggesting a legacy of resource extraction alongside the recreational infrastructure of the Challis and Boise National Forests. An extensive network of primitive routes, such as the Thatcher Trail and various Jeep Trails, provides insight into the movement of foresters and early backcountry travelers through this wilderness area.
