2011 Map of Green Island

About this map

Green Island sits in the waters of Lake Michigan, appearing here as it was surveyed by the U.S. Geological Survey in the early 21st century. This specific quadrangle focuses primarily on the maritime environment of the bay, with the small landmass of Green Island serving as the central navigational landmark. The mapping reflects the essential character of this portion of the Great Lakes, where the isolation of the island is clearly defined against the vast surrounding waters. Researchers interested in the coastal geography of Door County will find this sheet provides a precise record of the island's shoreline and position within the lake during this era.
