1950 Map of Turtle Lake

About this map

The Camp Grayling Military Reservation dominates the southern landscape of this mid-century survey, its boundary cutting across the winding course of the North Branch Au Sable River. This northern Michigan terrain is defined by a dense concentration of glacial lakes and wetlands, including the central Turtle Lake and the prominent Opal Lake to the west. The presence of several private landings and ranches, such as Whites Landing, Farrar Landing, and the Triple K Ranch, suggests a region deeply integrated with seasonal recreation and sporting traditions. Beyond the military grounds, much of the area is protected as part of the Pigeon River State Forest. Traces of earlier transit routes are visible in the path of the Old State Road, while several ruins and a Range Line Dam offer specific points of interest for local historians studying the area's development before 1950.
