OK so I have been asked the question and I did not know the answer. Bit of a nerdy question really, but what bit of natural passage in the UK is deepest vertically from the surface? Not from the entrance rather rock above.
Only really of practical use to those playing around with cave radios, so perhaps CREG know.
Unexpected contenders might be White Scar or Dalebarn.
Thanks
