At it's height Bolehill Quarry was one of best sources of millstones or grindstones until foreign competition virtually closed production overnight. The old stones were just abandoned and are slowly being reclaimed by nature. There's plenty of compositions to be found but this one particularly caught my eye especially during the short break in cloud cover letting the nicer winter light through.
