21st September 2017: Back in the day, there may have been more of us, but many of the team fell by the wayside, just me and Tav made the journey.
Along the route, up through Chamber 20 to the dig, there is plenty of evidence for some recent high-energy water flow, many of the mud banks have been washed-out. The water appears to have issued from above, so fast surface run-off likely, it has been rather wet recently. Maybe there's a higher network of passages.
We were not surprised to arrive at the dig and find it underwater. Spent a bit of time tidying away the tools and other equipment, before making our way back out of the cave, taking some stuff out with us. It is still a warm trip, even when a gentle pace, taking time to look around.
