Karen,
The Lake preserves bodies very well, because below 100 feet the temperature remains very low year around. There's been some discussion of this on the Great Lakes Shipwreck Research message board. For example, the body of a crewman still exists in the engine room of the wreck of Kamloops, which sank in 1927 off Isle Royale.
In the 1970s, there was a diver who drowned while diving off of the S.S. Gunilda. His perfectly preserved body was found some five to ten years later, entangled in the wreck.
I've even heard a story to the effect that old bodies from shipwrecks have been washed ashore during intense Lake Superior storms. It seems incredible, but then, look at the instances of the Edmund Fitzgerald and Kamloops. So I suppose it's possible.
If you take a look at the Gunilda website (
http://www.gunilda.com), you can see how well stuff is preserved in the Lake. Gunilda looks like how I hoped the Titanic would look - - before we found out, in 1985, what she actually looked like.
Dave, I haven't attended any, but I did watch the Discovery Channel program about the memorial services, and you're absolutely right - - bring a hankie, and maybe six boxes of kleenix, too.
Take care, everyone.
