John Cooper, Adrian Vanderplank and Jude Vanderplank. Took in 2 bags of sand and capping kit. One mix of cement taken down to bottom. With storm Alex making its presence known the cave was damp! I’ve never seen Four-Tonne Shaft as wet with water entering only a few feet down and making the entire shaft a real shower bath. Fortunately the stream flowing down the bottom tunnel was being captured by the hole Wayne had cleaned out near the bottom end a couple of weeks ago and so did not complete its journey to flow down into the current dig site. The boulder was capped and some of it cemented into wall. Hope the water doesn’t wash the cement out. 2½ hours.
