Hi Rampage,
Thanks for the interesting info.
Yes, remember reading about what was possible when the water levels were down. -Rather unlikely to happen again.
Some time ago, I looked down a couple of chambers off level F near the dam. One, a short crawl down a roofing shaft, lead to a smallish chamber with an awful roof. The rock was sticking out in jagged shards of differing lengths and looked as if it had been struck by a minor earthquake! There was lumps of a hard, cream coloured stone on the floor which I think may have been "chert" and which seemed very fresh. One could look down to water around floor G from there.
The other chamber, back in the direction of the dam, I looked into only briefly via a window. Was wondering if it's one of these chambers which ultimately leads to the top of that stairway?
I think the chambers and levels in this area of the quarry are duplicated either side of a fault, hence why the rock is in generally bad condition. Or alternatively it could represent 2 different veins - (old/new) but never been able to make up my mind on this one.
Don't have chamber numbers to hand, as it's all just a little too far east to be shown on the Cwmorthin plan I generally use, although I remember seeing a plan of this area in Graham Isherwood's Oakeley history.
This area, on the ragged edge of Oakeley, always has been remote and rarely visited and is not really recommended. The area around the dam is I believe now out of bounds anyway!
