Geez, there are dozens of ships exposed here in NW Mich. after a big blow.
Most of them were cargo vessels, who held basic staples. But,occasionally there were genuine treasure ships that came aground.
They are still out there.
During a 150 year period when cargo was moved mostly in smaller vessels (often built of wood), the average loss on the Great Lakes was one every six days, something like that. Not all of them would be all that interesting. Nowadays insurance fraud sinks more boats than the waves, I’d guess. ;’)
