Mysterious stone found at site of old Maine fort

From the Bangor Daily News:

Last week, crews working on a new entrance to the fort in connection with the nearby Waldo-Hancock Bridge construction unearthed a large hand-worked piece of granite that has become known as "the mystery stone." The granite is 17 inches thick and tapered, with a circumference of 51 inches on the fat end. There is a hole in the center, and the outer edges still bear the marks of the hand chisel that shaped it. The taper indicates that the stone was intended to fit into something, according to Tom Desjardin, historic-site specialist with the state Bureau of Parks and Lands. "Somebody spent a lot of time working that," Desjardin said Saturday at the site. "It doesn't make sense that they would put that much effort into something that was going to be covered up.">
