South Fork Flathead River carves a deep path through this portion of the Flathead National Forest, reflecting the era of postwar energy development in Montana. The northeastern corner of the map centers on the massive infrastructure of the Hungry Horse Reservoir, including the Powerhouse and Substation that transformed the regional landscape. This 1962 survey, with revisions from 1978, illustrates the transition from a remote wilderness to an industrial hydro-power hub.
