2017 Map of Palisades Dam

About this map

Palisades Dam stands as the central engineering feature of this Idaho landscape, where the Snake River is impounded to form the sprawling Palisades Reservoir. The map illustrates the convergence of high-mountain hydrology and human infrastructure, with the waterway hemmed in by the Targhee National Forest to the north and the Caribou National Forest to the south. Small settlements like Irwin, Swan Valley, and the namesake Palisades follow the narrow corridor of the valley floor before the terrain rises sharply into named peaks and complex drainage systems.
