Shipwreck Tour of Thunder Bay National Marine Sanctuary

[@johndavies1090]

Sad, but fascinating to watch. I'm amazed by how well preserved so many of these ships are, while others have little remaining. Clearly the way in which they met their end, and conditions below water must have a big influence on what happens to them.

A lot of thes wrecks were dove on when my fathers company "Pan Oceanic Engineering Corp" out of Alpena, Mich. in 1970/1974. B/4 GPS it was a hole differnt game. Not only did we have premium dive gear but we had a 20ton crane with hatch covers off the 'Nordmere",that we used to auger into the sand bottom(where applicable) as ankors over the wreck areas. We rented a submarine side scan sonnar for a week for a paid(by "Loyds of London") salvage of a sunken barge. Found the barge the first day,then found and dove about 20+ wrecks that week
