It turns out that C. W. Anderson lived in Mason, New Hampshire, not far from where I live, and the lost quarry is in the woods near the center of Mason. It's a pleasant hike or mountain-bike ride and the quarry is quite large and filled with water.

Though the quarry has not been active since the early part of the last century, there is still a great deal of evidence of the operation, including old roads, foundations, the Boston & Maine railroad bed, and some rusted cables and bolts.
