With Tav, Brockers and Jonathon.
My turn to dig, Tav clearing away, Jon on top of the slope, Brockers doing the haul and shuttle, bags and rock were stashed in the entrance.
Eventually, Tav sorted the dragline on the skip to make spoil removal from the dig-face easier. Digging was a bit slow to start, space was limited and just a bit awkward, as the space increased, excavation improved, and the little spade came into use. The saw was located and Tav shortened the handle on the mattock, this action made it easier to use. How able to sit-up in the dig and get to work properly with the spade, unfortunately, time had passed quickly, and the session was drawn to its conclusion.
Brockers and Jon had, earlier, moved back to clear the spoil from the entrance out to the surface, 34no. bags and 1no. rock. There were another 8no. filled bags left on the top of the slope.
I have arranged a return on Tuesday for more induced rapid speleogenesis, to make some more space and aid forward progress.
