I received an email yesterday from the epigrapher who deciphered the hieroglyphs on the GT Stone and he assured me the stones are not part of the Soper Forgeries.  He also provided me with some additional information about the stones which we hope will lead us to their present location.  I have another theory about their whereabouts, but am hoping to prove myself incorrect.  This is such a mystery and while it may remain as such, I am learning so much about the culture of the more primitive races of Michigan in the process of chasing these tablets, that the search is well worth the effort.
