Some are from freshwater lakes in Michigan's Upper Peninsula, and Wisconsin some are from Bonne Terre Mine in Missouri . This Great Lakes tug was built in 1912, and as part of its long historic career worked on the Mackinac Bridge. Dive clubs from around the Midwest contributed to the preparation for this hulk to be sunk in Munising Michigan on May 30, 1996. The Selvick was cleaned, painted and had hatchways secured open, making it a safe dive. One schooner still had much of its rigging intact - including deck lines and mooring lines.
Automobiles also look amazingly new.
However, once the materials are removed from the water, they do undergo oxidation at a tremendous rate. Also, winter storms and ice can do a lot of damage to a hulk left in less than 30 feet of water. Many frontier logging camps, tourist resorts, and communities disposed of their garbage by dragging it out onto the winter ice. Neal Skrenes 1996, 1997. Please do not use without permission.
