1986 Map of Palisades

About this map

Palisades Reservoir dominates this landscape, its waters filling the canyon of the Snake River as it winds through the heart of the Caribou Range. Compiled from surveys through the 1960s and 1980s, the map reveals a region defined by high peaks and tectonic transitions, including the extensive Lava Field and the complex terrain of the Blackfoot Mountains. This era shows the developed recreation and infrastructure around Swan Valley and Irwin, where mountain drainage systems like McCoy Creek and Rainey Creek converge toward the reservoir.
