This quarry was "in the town of South Thomaston, 1 mile west of Pleasant Beach and 7 miles south of Rockland." The granite from the quarry was reportedly a slightly bluish medium gray color with a medium to coarse texture. In 1905 the quarry measured about an acre of ground and had an average depth of 20 feet. Transport of the granite was by cars and horsepower on a track half a mile to the wharf near Birch Point. At the time of the report, the quarry had not been used since 1914.
