I thought that you might like to see a piece of an actual shipwreck. The waters of Lake Michigan were crystal clear on this particular day and as I looked over the side of the boat - voila! I could see a small part of history.
The area of Lake Michigan shoreline that I visit in the summertime is part of the Manitou Passage. The water in this area is home to 16 shipwrecks and occasionally bits and pieces of them sweep in with the waves or are uncovered after decades beneath the sand. FYI - shipwrecks are protected by the State of Michigan. It is a felony to remove or disturb any artifact found in the Great Lakes.
These beautiful (and dangerous) waters attract scuba divers (and marine biologists) who are thrilled to get an underwater look at two hundred years of marine wreckage. Can you imagine how interesting it would be to see the schools of fish that live in these underwater homes?
