As Dale pointed out yesterday in the comments, this quarry is located along Route 641 as you are leaving Newville, enroute to Newburg. He is the only one that had anything to say, maybe I need to put out an all call like Kevin did to see who if anyone is out there. I have a good idea who is looking at the fire history site but only know a few of you looking at the photography site.
This was a great place to stop and shoot, it gave me a chance to play with my wide angle lens. If you look close the sign in the center says no trespassing, but I didn't have my glasses on and I didn't think they meant me. I don't know how these look on your monitors but I do them on my laptop and the colors look much more vibrant and the black and whites look more alive not as flat. Maybe it is just my home monitor, or I need new glasses.
