Lake Huron surrounds the northern reaches of Drummond Island in this modern 2023 survey of the maritime boundary between the United States and Canada. The map highlights a complex archipelago of limestone islands and treacherous shoals, featuring the Harbor Island National Wildlife Refuge and numerous family-named points and bays. Inland, the southern portion of the sheet reveals the road network of Drummond Island, including S Sturgeon Bay Rd and S Sims Point Rd, which lead to the Drummond Island Airport. This area is characterized by its significant hydrographic features like Potagannissing Bay and De Tour Passage, which have long served as vital corridors for Great Lakes navigation. Local landmarks such as Seastone Point and Wreck Island reflect the area's nautical history and the physical challenges of navigating these island-studded waters.
