This chap has contacted DCA a couple of times now about help with making a shaft safe (on limestone). Being DCA, we can't help without landowner permission, which he does not have. I've directed him to UKC forum but if anyone wants to talk to him directly, go to the DCA Facebook page, and respond to his comment on our most recent post. His name is Jon. He is obviously keen and has the smarts to be asking for help. If anyone down south end of the Peak can help, drop him a message.
