Just before on the left a small grovel soon met a 1m diameter phreatic tube. Right ended with the same flowstone blockage, however left went for a few meters before closing down to a strongly draughting dig.
This dig was checked yesterday by myself and Robbie. After a few minutes digging I squeezed through a couple meters into an airbell with a too tight rift in the roof. Straight on the main passage continues but it almost completed full of mud. This is where some of the draught comes from, but it would require a lot of effort to push! It's a cold place
All of our work, including the surveying, is now completed and the pitch now fixed rigging (use at your own risk, it
is 9mm). Feel free to go and enjoy...
