2011 Map of Thompsons Harbor

About this map

Lake Huron and the northern reaches of Grand Lake define this coastal section of Presque Isle County. The shoreline is characterized by prominent landmarks like Observatory Point and Black Point, which frame the sheltered waters of Thompsons Harbor and North Bay. Inward from the coast, a complex network of islands sits within the larger lake basin, including Grand Island, Macombers Island, and the Three Sisters Island. The drainage of the land is visible through several waterways such as Schalks Creek and Monaghan Creek, which wind toward the coast. Local transit is facilitated by a grid of rural routes like N Grand Lake Hwy and Old State Rd, serving the residential developments around Black Bass Bay and the wooded interior toward Warren Creek.
