De Tour Passage Underwater Preserve, Protected water area in Michigan, United States
De Tour Passage Underwater Preserve covers part of Lake Huron and the St. Mary's River near Michigan's easternmost point, with Drummond Island as a key reference. The preserve protects multiple shipwrecks resting on the lake floor that divers can explore.
This passage became a critical shipping route in the late 1800s, connecting mining operations to major industrial factories across the region. The wrecks visible today are remnants of that peak era of Great Lakes shipping activity.
Shipwrecks scattered across this preserve tell stories of the maritime trade that once connected mining regions to industrial centers. Visitors can sense how vital water transport was to the region's economy by observing the physical remains of these vessels.
The wreck sites here are found in shallow water, making this location accessible to divers without advanced deep-diving skills. Check local regulations before planning a visit and avoid anchoring directly over wrecks to protect the historical remains.
What makes this preserve special is the presence of wooden ship hulls that have survived remarkably well in the cold waters. These wooden wrecks offer a rare chance to see construction techniques from maritime history without requiring deep diving.
