Below is a link to an article on exploration work in Ogof Igam-Ogam by CroydonCC and CDG members. Meant to be appearing in the CroydonCC Newsletter Pelobates 96 in the not too distant future.

How long is Sump Four?  How long is Thirty Years Itch?

Very interesting, thanks !

What a fabulous cave name

A conservative estimate of the horizontal passage in Thirty Year Itch and Sump 4 is 200 metres. Sump 4 is about 80 metres long.
Total cave length 700 metres+

Concerning the name it means zig-zag in Welsh which you might know. It got its name a long time before the kids TV program of the same name. With a Welsh dictionary clasped in one hand, we were initially going to call it Ogof Gwib which I think means slippery like a snake. However, on talking to Clare Jones of SWCC  whose Welsh was obviously better than ours, its name got changed to Igam-Ogam which much better sums up the nature of the passage.

Good stuff!

"....the almost mythical Pant Mawr Master System,,,"

Understandable, but we know it must be there.

Really good read Adrian! I enjoyed that.

Thanks for posting that lad, very enjoyable read. Best of luck with the continuing explorations.

Thanks for that. Hoping to get back in once it dries up a bit!
