With Jake, Tav, Brockers and Jonathon.
A rather disappointingly short session, the induced speleogenesis did not have the desired effect and the debris was quickly cleared. There are fractures but too tight to break-out. The narrow gap in the fissure has become filled with gravel and didn't look all that enticing. We spent some time looking around and discussing a couple of alternative options before making our way-out of the cave, and up to the pub after getting changed.
Following a conservation with Jake, over a pint, we'll persevere a little longer with the expansion of the narrow fissure. I might, just change the ingredients to give a little more oomph to the speleogenesis process.
