    Potawatomi Islands

    The Potawatomi Islands is the most common historic name given to the string of islands that delineate the transition from Green Bay to Lake Michigan, one of the Great Lakes.

    Overview

    The Potawatomi Islands is the most common historic name given to the string of islands that delineate the transition from Green Bay to Lake Michigan, one of the Great Lakes. The archipelago was previously named the Noquet Islands by early French explorers after the eponymous Michigan tribe, and the Grand Traverse Islands by American settlers. The largest of the islands is Washington Island, in Door County, Wisconsin. Washington Island accounts for 62% of the islands' combined surface area. Others include Plum Island, Detroit Island, Hog Island, Pilot Island, and Rock Island in Wisconsin and Little Gull Island, Summer Island, Little Summer Island, Poverty Island, Rocky Island, and St. Martin Island in Michigan. The broader term "Green Bay Islands" is used when additional islands located to the southwest are included in the island group.
