A quick pre pub trip on a Friday night. Doing the tourist trip in reverse.
Portering cylinders to Chamber 9. Gavin then preceeded to dive to '62m in sump 25 while filming for the new wookey video. He also lost a ?350 lens in the process. Sump 9 looked very inviting (until the divers stirred it up). MA and I then walked round the showcave to look at the other sumps and fit tourists before leaving.
Back down to the aven by sump 2, which we previously bolted to. MA and I looked at it again but concluded for the 2nd time that the calcite blockage was terminal. As MA was abseiling back down I noticed the floor was sounding hollow. After deploying the lump hammer I broke through the false floor into thick mud before hitting a layer of sand and a second thicker false floor. This was broken through and more mud excavated. The floor can still be lowered but forward progress was limited by tougher calcite. Back at the streamway a dam had been built by all the spoil thrown from the aven (sump 2 was blocked anyway). An exit was made with a return trip in mind.
Yet again back to the aven by sump 2 this time with more digging tools. MA and PW went on a pretties trip (PW 1st time in cave) while MG and I attacked the harder calcite with crowbars and lump hammers. Progress was slow due to the thicker calcite. We exited and convinced J-Rat to apply chemical persuasion when he got round to it. We will see what dent the explosives make in the blockage. Could this be the by-pass to sump 2 '''
