1950 Map of Lake Margrethe

About this map

Camp Grayling Military Reservation dominates the center of this Michigan landscape, indicating the long-standing military presence and training grounds surrounding Lake Margrethe. To the north and west, the map details the protected lands of the Au Sable State Forest and the Hanson State Game Refuge, where the Manistee River and Goose Creek wind through the terrain. Evidence of the mid-century recreational and transport network is clear, with several water-access points like McIntyre Landing, Danish Landing, and Collens Landing lining the lakefront. The New York Central railroad cuts through the eastern edge, while numerous named elevations such as Argonne Hill, Red Arrow Hill, and Mont St Martin define the ridges south of the military camps. This 1950 data, updated in the late 1970s, captures a transition between wilderness management and active military utility.
