It is indeed Cove Hole so over to you Fulk 'cos you were close enough. And it is indeed Kath Gilbert, but its a 'wezzit' rather than a 'whosit' so Langliffe is going have to miss out!
Yes, I agree Toby; there are many questions to be answered about those reef knoll caves.
OK, try this one. What's the name of this very substantial resurgence, which has some similarities with Turn Dub? It's a bit off the beaten track but I'll start with a clue; it's in the Dales. If cavers aren't aware of it they should be, which I think justifies using it here in this fun topic. (I hope I've not used this one before!)
Slightly wild guess but is it up near Great Asby (which is technically in the Dales now)? Not sure how it would resemble Turn Dub but it is off the beaten track.
