I've wondered where this was of for a few years but as a consequence of legendrider's recent additions I may have worked out where, I'm not too sure but the entrance looks a bit like Mr Mikes's 2007 and LeeW's 2015 photos of the drainage level without the addition of Dad showing a worryingly masochistic side to his nature. I hope AditNow's version of netnanny doesn't treat this as mining porn! :o

Anybody feel bold enough to a) look at the photo, b) comment on the possible location, date probably mid 1980's.
