About this map

Lake Huron dominates this 1980s planimetric survey, which focuses on the northernmost tip of Michigan's thumb. The map details the transition from the maritime expanse to the rugged coastlines of Pointe Aux Barques and Burnt Cabin Point. Inland, the settlement pattern is sparse, defined by small communities like Port Austin and Huron City that are connected by a network of drainage ways including Bird Creek and Willow Creek.

Evidence of local industry remains visible through the quarries near Grind Stone City, a location synonymous with the region's historic abrasive stone production. The map also delineates the international boundary between the United States and Canada and the provincial-state divide of Ontario and Michigan, positioned far out in the deep waters of the lake. These borders, alongside markers like the approximate mean lake elevation of 177 meters, underscore the importance of the Great Lakes shipping lanes and resource management during this era.
