About this map

Thompsons Harbor and the jagged northeastern coastline of Lake Huron define this 2017 study of Presque Isle Township. The map centers on the transition between the lake's open waters and the intricate network of inland waterways and islands. Grand Lake dominates the southern half of the sheet, its irregular shoreline punctuated by Grand Point and Birch Tree Point. Numerous islands, including Indian Island, Bear Island, and the cluster of the Three Sisters Island, are scattered throughout these waters, indicating the complex glacial topography of the region.

Residential development is concentrated around Presque Isle Harbor, where a grid of modern streets like Ponderosa Cir and Bay Shore Dr meets the shore of North Bay. Inland, the landscape is largely defined by drainage systems like Monaghan Cr and Schalks Cr, which feed through low-lying terrain. The map captures the balance between the established coastal community and the preservation of the natural harbor environments.
