It's caused enough problems already. Some investigators, including local real estate developer Ed Godwin, say the site is nothing more than a hoax. But it's still unclear why they went to all the trouble to make it look like some kind of modern Stonehenge. The strange complex does bear resemblance to England's famous circle of stones. There are also chimneys and cairns and ledges and portals and an astronomically correct rock calendar the size of a cow pasture.
Some skeptics say the stone construction was the work of an Indian clan.
But radiocarbon dating indicates the site was built some 4,000 years ago, more than 3,000 years before the arrival of the Pattee tribe. One scholar who examined the ruins shortly after the turn of the century found evidence that convinced him the builders were Phoenician in origin. Another, William Goodwin, was convinced that outcast Irish monks were behind Mystery Hill's construction more than 1,000 years ago. But Bob Goodby, president of the New Hampshire Archaeological Society and professor of anthropology at the University of New Hampshire in Durham, said that no reputable archaeologist took the pre-Columbian lure seriously. There are no signs that are associated with other megalithic sites elsewhere in Europe.
