On a traffic island in downtown Fitchburg, Massachusetts, stands a 110-ton granite boulder, known to locals as “the Rollstone Boulder”. The boulder is a glacial erratic, which means that it’s not native to the area where it rests, but was carried by glaciers from far away land and deposited there when the ice melted away. But the glaciers didn’t move the boulder to where it currently stands. Men did it.
The Rollstone Boulder was originally located at the summit of Rollstone Hill, about a mile away. The boulder was deposited there during the last ice age about 10,000 years ago by glaciers that covered North America. It is believed that the boulder came from around central New Hampshire, perhaps Bedford or Concord, a hundred miles away, because of the similarity in composition of Rollstone Boulder and the stones in that area.
KitsuneFox: syzygy - posts I have made here do not receive much attention. I may do a detailed writeup of the now lost Edgemont Park in PA, one of the first electrified trolley parks in the world, but still debating. I'm missing 1 key bit of information.
