Been inside Cononley a couple of months back. We only went in around 100m (to the first collapse, 2nd collapse was about another 8m further in but had been shored up)
In this photo I'm stood on the spill from the first collapse, looking out and just under the upper adit (The ladder in the pic allows access to the upper adit, though it should really be placed where I'm stood as the hole above me is too large to stride across)..... For some reason we left just after this pic was taken but there's nice tool marks to be seen in there... There's even still the odd candles sitting on pegs.... I will return, take better pictures and get a whole lot deeper.
