About this map

Thompson's Harbor State Park dominates this coastal landscape along the shores of Lake Huron, protecting a series of limestone cobble beaches and wetlands. The intricate shoreline is defined by landforms such as Observatory Point and Black Point, which frame the namesake Thompsons Harbor and North Bay. Inland, the geography is heavily influenced by the presence of Grand Lake, which is dotted with numerous landmasses including Indian Island, Allen Island, and Bear Island.

Settlement patterns are concentrated near the water, particularly at Presque Isle Harbor and Grand Point. The map details a network of secondary roads and trails that navigate the low-lying terrain, including Old State Rd and the Thompson's Harbor State Park Loop 3 Trl. Several waterways, such as Schalks Creek and Monaghan Creek, drain the interior forest and marshlands toward the Great Lakes, illustrating the region's complex hydrological connection between inland lakes and the open harbor.
