About this map

Johnswood sits near the western edge of this island landscape, where the international boundary between the United States and Canada cuts through the waters of Lake Huron. The terrain is defined by a series of significant coastal features, including the prominent Marble Head in the northeast and the sweeping curve of Big Shoal Beach along the southern shore. Inland, a complex network of wetlands and small water bodies like Jarvinen Marsh Lake, Pine Lake, and Dickenson Lake suggests a low-lying, water-dominant environment characteristic of the region's geography.

Transportation is marked by remote corridors such as S McKenzie Rd and Glen Cove Rd, which provide access to the various points and coves. The presence of False Detour Channel at the southeastern corner underscores the maritime importance of this area, serving as a critical passage between the islands. This survey captures a moment in the early 21st century when the balance between small settlements and the surrounding wilderness remained largely unchanged.
