1952 Map of Duncan Peak

About this map

Michigan Bluff stands as a primary focal point in this 1950s survey of the Gold Country high ground between the North Fork and Middle Fork American Rivers. The map documents a landscape heavily shaped by hydraulic and lode mining history, evidenced by the extensive Big Gun Diggings and a dense network of tunnels and shafts like the Golden River Tunnel and Pacific Slab Mine. Many once-active settlements are recorded as mere locations, including Deadwood (Site), Forks House (Site), and Star Town (Site), illustrating the shifting population of Placer County after the initial gold rush. Forest management infrastructure is prominent across the Tahoe National Forest, with high-elevation watchpoints at the Duncan Pk Lookout and the Greek Store Guard Sta overlooking deep canyons like Secret Canyon and Blue Canyon.
