I recently read the account in Boyd Dawkins's book Cave Hunting of his descent of Alum Pot in 1870, which was organised by John Birkbeck (of Gaping Gill fame). This was a direct descent by winch, following Birkbeck's earlier descent via Lower Long Churn and The Bridge in 1847.
I seem to remember there was a Descent article about this a while back - does anyone recall which issue? Or have a copy they could scan and send to me? And does anyone know anything about the "three ladies" who went to the bottom in 1870?
Finally, does anyone have any further info or references about Birkbeck and his friend Metcalfe, who also took part in these expeditions?
Thank you in advance.
