I visited Redhurst - perhaps 10 years ago? The months leading up to our visit had been much drier than the average summer (whatever that is now!). In fact, that summer had seen very little rain up to that point; none of those major flooding events that other summers have had!
There was still a couple of ducks if I recall correctly. One duck, had an eye-hole above that could be passed through, but others found it easier to totally submerge (where it enlarged in size underwater) and pop up on the other side. It was somewhere near here, where a climb up is reached, and looking back down makes you realise if the sump rose at that point (which it does) would lead to a very serious predicament!
We almost reached Pink Chamber - somehow lost the route, but from reading the description afterwards again in the pub, we must have practically been right next to it! To be perfectly honest, there was a last-minute-forecast update, of a very small chance of a small thundery-downpour much later that evening (after we'd planned to be out), so we opted for a quick in-out. Even with the forecast good for the actual trip (with some leeway too), I think it still played on our minds a bit (it did mine anyway) - and distracted us a bit towards the end of the cave. As it happened, a thundery-downpour never materialised.
Some returned a couple of days later, and made it to Pink Chamber with no problem at all - a couple of days later the weather broke - big time!
