Once all that was done we went back to 'quality belays' traverse. Wook derigged rope whilst george started rigging a sensible pitch into wellypopper instead. Gardened part of the massive pile of boulders round the edge of the hole. He had trouble with cratering and one bolt cracking and it was getting late so Wook put in last 2 (only 2 hiltis left!). Then we packed up all the (unused!) rope and drill and stagerred out with 3 bags. Eventually got out (leaving one rope bag in china tied to rope, and drill plus other rope bag at Coldest PIE. Forgot (and out of time) to derig connection pitch.

In total back to the future travrse and quality belays pitches have 20 hangers and one sling on them. Details in survey notes. None of the ropes are labelled. BTTF has the one left for a year. 2014 10mm? ~55m? The top is an 11mm 12mish bit. The pitch down is ~18m. Could be joe's rope? +

107, Notwindow into Heat Recovery Ventilation
+ +

+ Very slow start after yesterdays epic. But too hot to fester all day so forced to go + caving. Decided to go and finish Notwindow pitch as not too far down, gear there, and Ol wanted + his hangers back. Set off rigging last ~10m of pitch from pre-placed bolt (!). Wook rigged whilst + george poked hole at back of main drop landing. Turns out this goes through tight spot into + climable rift. George ended up looking into passage at foot of pitch near where Wook was coming + down, but he couldn't actually get through. After putting in a rebelay Wook arrived at the floor. Pitch + continuation is wet and quite narrow - looks like modern development, but there is a passage going + off where you land (2-3m high, 0.6-1m wide rift. Round corner is straight rift for 30m. 10m along + is very windy passage on L(draughting towards you (out of cave). Beyond rift seems draughtless, + but pitch-climb at the end was not descended. QM B. On R opposite draughting passage is smaller + passage which also has a 10m drop after 5m. QMB.

+ +

+ Surveyed up windy passage (Heat Recovery Ventilation). It was bloody cold (and not very big), but + kept going steadily uphill for a couple of hours of surveying (20 legs). We were hoping for it to + get to something (it clearly goes somewhere) but nothing happenend before we had to turn + round to hit our callout, allowing for surveying up the pitch and derigging and dragging drill + + rope out of cave. Interesting passage. QMA (and hole in the floor at last station, QMB)

107 Derig
+ +

We weren't quite sure how many tacklesacks derigging 107 would take, but almost certainly more +than the number of deriggers available (3). So this might turn into a bit of a mission. Jenny set +off first due to being an early bird and set off to go down to china and derig the blown-out +connection rope, into the part-empty tacklesack at the bottom of the cina rope, then head up the +China pitch hoping for someone to turn up to relieve her of a baggie beforeit got ridiculous. Wook +arrived as she was nearing the top of the pitch, so that worked OK, reporting that the other half of +the cavalry (George) was still asleep when he left camp, but would hopefully get sunned out of his +tent and turn up in another hour or so. +

+

By the end of 'Too Bold' we already had two very full and heavy bags of rope, so set off up the +rift carefully trying not to fall off and die. Fortunately we met George at the twin-pitches, so +gave him a fat baggy to take out, and Wook followed, endeavouring to leave the bag such that he +could get back and relieve jenny as soon as she had another full one. This team-bag-shuttling game +actually worked rather well as Jenny derigged steadily and Wook and George went back and forth in +ever-decreasing lengths of cave. There was no danger of being too cold! +

+ +

In the end the 5 very full tacklesacks were all out by 3pm (~6hrs) which was about half the time +Jenny had thought that it might take. So we had time to sort some stuff, take Wook and George's +stuff from the 76 bivi and carry a load of heavy shit down the hill in time for dinner.

+ +

The only thing left rigged in the cave is one hanger and a 12m bit of rope on the window pitch +immediately before Pushing The Envelope squeeze.
