Early French explorers named the dangerous shoal-studded passage between Lake Michgan and Green Bay "Porte des Morts", or Death's Door. Since then, hundreds of ships have dramatically come to grief along these rocky shores. Many fascinating archival, land, aerial and underwater photos bring to life these shipwreck tales, the legend of the Poverty Island Treasure, plus much more.
