About this map

The Caribou Range dominates this mid-1980s landscape, serving as a divider between the high-altitude basins and the powerful Snake River valley. The map reveals a region defined by federal land management and massive water projects, from the Caribou National Forest to the expansive Palisades Reservoir. To the west, the urban edge of Idaho Falls and Ammon gives way to the irrigation-heavy drainage of Willow Creek, while the Union Pacific RR follows the northern corridor.

South of the mountains, the Grays Lake National Wildlife Refuge and the northern tip of the Blackfoot Reservoir indicate the marshy, interior drainage characteristic of this Idaho-Wyoming borderland. Resource extraction is evident in the Caribou Basin at the Monte Cristo Mine and Evergreen Mine. The map traces the winding paths of US Highway 26 and State Highway 34, which connect small settlements like Swan Valley and Alpine Junction through the high passes and river canyons.
