The Au Sable River winds through this 1951 survey of Crawford County, defining a landscape dominated by the Camp Grayling Military Reservation and the southern reaches of the Huron National Forest. This era shows a distinctive network of "truck trails" cutting through the timber and training grounds, such as the Ketcham Truck Trail and Bucks East and West Truck Trail, which provided essential access for forest management and military maneuvers.
