ok, i've been looking at aerials and satellite images of downtown atlanta for years...several years...and have never seen or heard about this mine less than a 1/2 mile from Georgia Tech. Used to roam around that area all through the old railroad buildings until 3 or 4am, sometimes even until sunup. Anyways, who wants to go out and take some pictures sometime??? I still can't believe i've never run up onto or even heard about the Bellwood Quarry...
Here's a recent aerial i screen captured of it...
