2023 Map of Point Detour

About this map

Garden Peninsula and its southern tip at Point Detour dominate the northern landscape of this coastal survey. The terrain here transitions abruptly into the vast waters of Lake Michigan, which occupies the majority of the quadrangle. Further south, the map identifies Summer Island, part of an archipelago chain that historically served as a critical navigational waypoint for maritime traffic entering Green Bay. The sparse land features emphasize the maritime character of this portion of Delta County, where the topography is defined more by the shoreline and the submerged depths of the Great Lakes than by inland development.
