Not sure I deserve any praise after your clues, Adrian! 😂 I don't have time to look for a photo now and I've posted a few up lately so...

Well done Huw you got it!

Nope. Two more clues! In theory, the name of the cave would not be out of place in the Yorkshire Dales

Not that one, this cave is a fair bit shorter.

No not in Ogof Ffynnon Ddu

Of course that doesn't include my little clue about pitch length:)

Yes, I thought somebody might get it with my little clue!

Sorry not Pwll Dwfn. The pitch in this cave is alot shorter than those in Pwll Dwfn.

In theory, I thought this would be easy to get as there are less pitches in S.Wales than up north!

Sorry rather obscure!

Yes, a real collectors item. The sump passage when it occasionally dries out does have quite a draught but the choke prior to the stream...

Yes, photos taken a while ago. The dig at the end has potential, but not easy and very weather dependent (or was) :-) . L to R Me...

Ogof Ffynnon, Ystradfellte?
