An older article from Discover Magazine's Karen Wright discusses the quandary of "America's Stonehenge" and the mix of what appear to be post colonial additions and "stone-on-stone" quarrying methods. Will all the possibilities ever be sorted out? Probably not. The article, Yankee Doodle Druid is light-hearted, but includes information from Gary Hume, the New Hampshire state archeologist at the time of the article, supporting that at least some of the stone on the site is made from precolumbian stone quarrying methods and that it should be listed in the National Register of Historical Places, if only because, ".... it had been celebrated in so many dubious theories of pre-Columbian visitation" and "... exemplified nineteenth-century commercial stone-quarrying techniques as well as Native American occupation."
Something is not right. This message is just to keep things from messing up down the road
