2018 Map of Green Island
USGS Topo · Published 2018About this map
Green Island sits at the maritime intersection of Wisconsin and Michigan, positioned where the waters of Green Bay meet the open expanse of Lake Michigan. This 2018 survey documents the precise aquatic boundaries between Menominee County, Michigan and Door County, Wisconsin, illustrating how state lines are defined by deep-water channels. The map is primarily hydrographic, focusing on the navigational relationship between the small, isolated landmass of Green Island and the surrounding bays. It serves as a modern record of the shoreline and jurisdictional limits in a region defined by its Great Lakes geography and interstate shipping lanes.
