2022 Map of Green Island

About this map

Green Island sits at the maritime intersection of three major regional counties in the waters of Green Bay. This survey captures the isolated landmass and its surrounding nautical environment, where the boundaries of Menominee County, Michigan, and Marinette and Door counties in Wisconsin converge. The map is defined primarily by the open expanse of Lake Michigan, emphasizing the island's role as a distinct navigational landmark in the bay. The precise boundary lines cutting across the water highlight the complex jurisdictional divisions of the Great Lakes, showing how these invisible lines segment the water between different states and local governments.
