Me and Ant explored the whole adit today once we dug out a channel to drain the water as it was over wellie deep. The adit goes for around 300ft with a few blocked off passages with rocks. One passage you could crawl thorough but we didn't have suits on to try.

The elderly farmer turned up on his tractor whilst kicking out a drainage channel . After a short chat he let us borrow a pickaxe to help with the digging.
