Alpena/Thunder Bay is known as "Shipwreck Alley of the Great Lakes"

“Shipwreck Alley” is the final resting place for scores of ships that have fallen victim to Lake Huron’s murky fog banks, sud­den gales, and rocky shoals. These range from wooden schooners more than 150 years old to side­wheel steamers to modern freighters. The cold, fresh waters of Lake Huron slow down natural processes that corrode iron and degrade wood, so even the oldest shipwrecks are often in excellent condition. The shipwrecks of Thunder Bay tell us a great deal about life on the Great Lakes over the past 200 years, and offer opportunities to study the structure, rigging, and other details of sailing ships that are hard to find any­where else in the world.
