As much as I would like to beleive this is a dolmen, the faux celtic inscription was a dead givaway. If this were true, surely archeologists would be deciphering this inscription and the general public would have some knpwledge. Not to mention the simple truth, what would an ancient group of explorers be doing in the North Salem area? There seems to be no major river or natural landmark that would draw any foriegn peoples to the area. I have to side with geology, this is an 'eratic' rock, and still worhwhile checking out.
Something is not right. This message is just to keep things from messing up down the road
