In the early 20th century there was a wreck dragged out of Lake Champlain at Crown Point and put on "display" in the fort.  It rotted and crumbled until a grass fire consumed it.  When will people learn it is just better to leave sunken wrecks in the water where they can be carefully studied, measured, managed, and preserved where they have already been preserved for centuries???  There is of course urgency to do this underwater archeology because of possible new threats such as zebra mussels.  We just don't have the technology yet to raise and preserve shipwrecks, however.  Even the Vasa in Sweden is deteriorating despite the best possible preservation treatment.  The raising of the Philadelphia by Hagglund at Valcour Island was something of a miracle.

You might also add to that list the "Trumbell" who, like the Ticonderoga was covered by a wooden structure with a slate roof.  When the roof collapsed under the weight of a heavy snowstorm it too was lost.
