About this map

The Au Sable River carves through the landscape of the Huron National Forest, dominated by the extensive Alcona Dam Pond created by the Alcona Dam. This 1970s survey illustrates a region shaped by hydro-electric infrastructure and forestry, with a powerplant and substation situated at the dam site to harness the river's flow. The settlement of Curtisville serves as the local hub, featuring the Curtisville Civic Center and the Curtisville Cem nearby.

Beyond the reservoir, the terrain is dotted with numerous small water bodies including Hoppy Lake, Sunny Lake, and Honawan Lake, alongside several scattered gravel pits that suggest local road-building or industrial activity. The boundary between Alcona Co and Iosco Co runs through the southern portion of the sheet, dividing the townships of Curtis and Plainfield. This map preserves the mid-century layout of forest service roads and county routes like Bamfield Road that provided access to the river valley.
