2017 Map of Lime Island

About this map

De Tour Village stands at the maritime threshold where the Saint Marys River meets the northern expanse of Lake Huron. This 2017 chart delineates the complex international boundary between Michigan and Ontario, winding through the shipping channels of the De Tour Passage. The landscape is defined by an archipelago of limestone outcrops and islands, including the prominent Lime Island and the cluster of Sweets Islands near the mainland. Inland, the terrain softens around Caribou Lake, where local landmarks like the Sacred Heart Cem provide valuable touchpoints for genealogists. The map also captures the intricate coastal geometry of Potagannissing Bay, dotted with smaller features such as the Pipe Island Twins and Andrews Island, reflecting the area's enduring character as a strategic waterway and recreation destination.
