1957 Map of Alpena

About this map

Lake Huron and the North Channel dominate this mid-century maritime landscape, bridging the international boundary between Northeast Michigan and Ontario. Along the Michigan coast, Alpena and Rogers City serve as the primary hubs, supported by the Detroit and Mackinac RR and significant industrial activity at the quarry near Adams Point. Military and maritime safety are anchored by the Alpena Air National Guard and a Coast Guard Station near the mouth of the Thunder Bay River. Across the water, the expansive Manitoulin Island and Cockburn Island are detailed with several reservations, including the Manitoulin Island Indian Reservation No 23, and inland waters like Lake Mindemoya. This survey captures the transition from mainland forest tracts like Alpena State Forest to the complex island chains of the northern channel during a period of established cross-border navigation.
