At this point I am not quite sure to what to make of this particular location. The two stones in the center of the photograph have vertical grooves on their entire lengths with a single horizontal groove near the tops. Whether the two were spilt naturally or by hand I am not sure.There is no other evidence of colonial quarrying for a few miles. The stonewall visible in the background appears to be entirely made of natural field stone. The area at the bottom center of the photograph appeared to be the partially-buried entrance to a hole or chamber. This one is going to require a return trip in the Spring. I also need to go through Thorson's "Exploring Stone Walls" again as well as Mary and James Gage's fine publication "The Art of Splitting Stone" which is a fascinating treatment of colonial quarrying methods. Thorson's book cleared up a mystery for me a few years ago when we came across a massive stone wall while living in Maine. This wall was over six feet tall and over ten feet wide. It ran for perhaps 300 feet thru the woods in a straight line. In all my years of traipsing the woods of New England and the Maritimes I'd never seen a stonewall so massive, until I saw a picture in Thorson's book which he termed a disposal wall used in field clearing. This thing was massive, and I concluded it made sense after studying more of the area. In fact...I think I will dig out a couple of photos from my Maine days and post them:
