Wreck Location Map
Vessel Type
Wreck Type: Construction Crane
Description
The construction crane lies upright on the lakebed, with its massive boom collapsed forward and partially resting on the bottom. The unusual positioning of the crane and the intact nature of the wreck create an extraordinary underwater landscape. This unique site offers divers a chance to explore a modern piece of industrial equipment, providing a stark contrast to the more traditional shipwrecks found in Lake Huron.
History
In the fall of 2005, a tugboat towing a barge laden with heavy construction equipment encountered rough seas near Drummond Island while heading toward DeTour Passage. The challenging weather conditions caused the tug to lose partial control of the barge. During the struggle to stabilize the vessel, a large construction crane toppled from the barge and sank to the bottom of Lake Huron.
Efforts to retrieve the crane were unsuccessful, and it remains submerged to this day. The incident highlights the risks of transporting heavy industrial equipment across the unpredictable waters of the Great Lakes, where sudden weather changes can escalate routine operations into hazardous situations.
Significant Incidents
- The crane rests at a depth of 70 feet, positioned south of Espanore Island along the southern shore of Drummond Island.
- The site is approximately 3.75 miles east of DeTour Passage, a heavily used navigational route.
- Coordinates: 45°55.163′ N, 83°49.463′ W
Final Disposition
The crane is largely intact, with its upright position and collapsed boom offering a dramatic underwater scene. The lake’s cold, fresh water has helped preserve the structure.
Current Condition & Accessibility
The depth of 70 feet makes this wreck accessible to recreational divers with moderate experience. The site provides a unique diving experience, though caution is advised due to potential currents and weather variability in the area.
