1973 Map of Roy Lake

Evidence of the region's logging and transport history is etched into the earth through features like the Charcoal Grade and an old Railroad Grade south of the Tahquamenon R. These linear paths, alongside Skyline Road, indicate the industrial utility of the forest before the establishment of recreational sites like the Sixteen Creek Campground. The map preserves the mid-1970s state of this wilderness, showing a transition from timber-resource management toward conservation and public use.
