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.
