About this map

Lake Huron defines the northeastern boundary of this coastal survey, where the jagged shoreline of Presque Isle County meets the deep waters of the Great Lakes. The map illustrates a landscape dominated by complex waterways and island chains, specifically within the northern reaches of Grand Lake. Named landforms like Macombers Island, Bear Island, and the Three Sisters Island cluster near the coast, suggesting a haven for boaters and naturalists. The primary settlement, Presque Isle Harbor, sits near the protected waters of North Bay, served by a network of local roads such as Grand Pointe Hwy and Lakeside Dr.

Inland, the terrain is characterized by a series of low-lying wetlands and seasonal drainage systems, including Schalks Cr and Monaghan Cr. Significant coastal landmarks like Observatory Point and Black Point anchor the northern edge of Thompsons Harbor. The prominence of Us-23 running through the center reflects the area's development as a corridor for travel along the Michigan coast, connecting isolated bays and inlets to the broader region.
