Term: Death's Door
Definition: the entrance to Green Bay from Lake Michigan. Description from John W. Hunt's 1853 Wisconsin Gazetteer: "DEATH'S Door, the

entrance from Lake Michigan to Green Bay, between Plum Island an the main land of Door County."

Some believe that Death's Door got its name after a large Indian war party was destroyed there in a sudden storm. Early French and American travelers heard and repeated the story about "a hundred Indians dashed against these rocks and killed in a single storm." Some think that French fur traders spread this story to keep others from coming to the area. In fact, the name Death's Door comes from the French name, Porte des Morts. Due to its strong currents, fierce winds, and rocky shores, Death's Door is definitely known as a killer of ships. These conditions have been hazardous (haz ar dus, very dangerous) for all ships, but especially for sailing vessels. Lighthouses built on Plum Island (1848 and 1896) and Pilot Island (1850) helped, but hundreds of vessels have been lost or damaged in the Death's Door area. We hope none of Death's Door Marine's Fleet will be part of this legacy. Our goal is to make safe harbors to prevent further tragedies from happening. Now if we could only get the DNR to agree as well..............
