You have to see the plaque to answer two questions.
S 33 51.ABC E 151 07.DEF
ABC = The year that 92 English-speaking prissoners captured in Canada were exiled in Van Deamen's Land minus 1296=ABC
DEF= The year this plaque was unveiled by Pierre Elliott Trudeau, Prime Minister of Canada minus 1711=DEF
A picture would be appreciated but not necessary
So calculation would be needed to arrive at the coordinates fo GZ.
Thank you to my new geocaching friend Calypso62 to make this encredible cache accessible to all geocachers.
