Balcony - 90b
Same place, same time. Took compass and clino this time and surveyed up south end to a pitch. George went back to chamber and furtled through a passage to a place where he came out of the bottom. Also climbed up the rift through high wet bit. Meanwhile Dave had done his pitch and balcony ledge traverse to big passage. We surveyed into it, plumbed down, then across hole. At this point I got suspicious of how fast George was taking notes. Turned out he had drawn no diagrams at all. I went to sleep while Gorge got coached by David. Down the end under a low bit, David pushed a rock off a sandy slope. Sounded like the whole world was ending. Even George lost his cool. We cowered against the wall for 20 secs. The reverberating echo on the ceiling made it appear from above. Detackled, Luke and Rob joined us, went and trampled the dead bat in the north end, while George & I bodged a survey drawing in this chamber.
