14th May 2017: with Brocker's. Also, Ray Deasy and Richard Abbot (MNRC).
Brocker's and me planned to dig the choke at the end of Sandy Tunnel, to which end had bought along the capping gear. The other two went for a tour around and into Young Bloods in Wigmore.
We detoured on the way to the choke along the sixty-metre crawl, which is really more like 30m to assess the prospects there and, if necessary formulate a plan. An interesting looking space beyond has cool air emanating from it. The left-hand side is dominated by what appears to be a large, possibly detached flake, a few holes in the more competent right-hand side might be the best option. Anyway, that's a job for another day onto the choke.
Quickly, I got the capping gear into action and reduced a couple of large boulders as required, this enabled more digging. Removing smaller boulders, cobbles and some sticky mud, gaps could be seen at stream level.
Some shoring work might be needed, just to be on the safe side, scaffolding tubes would be a good option.
We were joined by the MNRC contingent briefly before they headed out of the cave. We carried on digging for a while longer before we, too made our way out. Good session.
