Nicholas, was there a chock-stone at the top of Dexter? I've dont it numerous times but I don't remember a chockstone, it is several years since I've done it though. Is it possible that the chockstone is a new feature after a less recent collapse than the latest?
Do you have any photos of the chockstone before its demise?
I've done most of the lines on Bristly Ridge many times. I quite liked the Dexter of several years ago, but even then I would only ever do it there was nobody above.
I don't think I will be going anywhere near it for the foreseeable future, there is to much debris and probably other stuff waiting to come down!
