76 - Brave New World
Didn't feel like carrying tackle through the Test Tube again, so took survey gear to tick off some leads (hopefully). The first lead we looked at was the tube on the right around halfway along, near the probable 99 connection. It got progressively narrower, and then there were some small pristine white stals. We decided that it would be hard to get past them without touching them, so surveyed out. Continued into Brave New World, and turned left to survey the oxbow passages, these are small and crappy and the 3 passages end up uniting and going to a pitch in a stream canyon – we surveyed to here and attempted to plumb the pitch. It is ~6m deep. Still had time left so went the other way along BNW, round the pitch and to the chamber we started surveying from on the 25th. Looked down the passage on the right, this gets bigger for a bit raising our hopes of this being the Train Tunnel passage we had been looking for, but it got lower and a crawl led to a big aven chamber which looked not too hard to climb. From the chamber it was not obvious where we had come from as it all looked small, so Olly named it "No Ways Chamber" though in fact I found another crawl out near ours that became vadose passage of a reasonable size to an aven – this is still to be surveyed.
