The delta of the St Clair River defines this 1936 survey, where the international boundary between United States and Canada threads through a labyrinth of channels and islands. On Harsens Island, a network of secondary roads such as La Croix Rd and Columbine Road connects small riverfront settlements like Sans Souci and Maple Leaf with local landmarks including St Marks Ch and the Harsens Island Sch. The mainland community of Algonac sits at the northern edge, bordered by Oaklawn Cem, serving as a gateway to the intricate waterway system.
