Hungry Horse Reservoir South Fork Flathead River dominates the center of this 1958 survey, showing the landscape as it appeared shortly after the reservoir's creation. The map documents early recreational and engineering infrastructure within the Flathead National Forest, including the Devils Corkscrew Campground and Peters Creek Campground. A notable detail for industrial historians is the notation of Core Drill Holes on the eastern shore near Corkscrew Creek, likely related to the geological assessments for the massive dam project downstream.
