2018 Map of Green Bay (All Water)

About this map

Lake Michigan and the expanse of Green Bay dominate this specialized nautical survey, where the terrestrial world is reduced to a single diagonal boundary line. This 2018 chart represents a distinct portion of the Wisconsin maritime landscape where no landmasses are present, focusing instead on the aquatic intersection of two prominent counties. The Marinette Co and Door Co administrative line cuts across the water, providing a rare perspective on how legal and regional boundaries are maintained even miles from the shoreline. Researchers of maritime history or administrative cartography will find interest in the precise placement of this county divider through the open waters of the bay.
