204 - Underworld / Sirens push + survey
Finally ready to roll pushing: looked at 03-29A rigged handline to edge of large chamber – no rope so leave that, plus 03-30B which needs a high-level traverse. (See our 22nd July trip.)
Ticked off + surveyed 03-28B, 03-27B and 03-26B. I think 03-25B can be downgraded to a "C" QM. Then up to crystal pool. Surveyed chamber at 03-31B. Nial climbed up to the mud filled pocket on the left of the chamber – apparently choked with mud. The small pit in the floor of the chamber is blind except for a miserable boulder-filled hole which you can get to the other side of from a small passage on the opposite side of the passage as 03-25B. There is a hole over your head in the chamber but Nial said the banks of mud would make it very hard to get into, plus a miserable little hole on the opposite wall. Then surveyed from 03-21B to 03-22C to complete a small loop. 03-20B doesn't exist, just mud-filled, though there is a miserable thin rift in the floor of the chamber it's in. 03-19C is still there (actually there are two roof tubes but the more promising, higher one would be tough to get into). Re-checked 03-23C – not at all promising, and 03-24C likewise – a v.steep climb.
That seemed to tick off all the horizontal leads in Sirens (boo-hiss) so we went back to Eeyore and Earl started to bolt 03-3B. Whilst he started, I checked 03-5B – it's a blind pit, only 4m down. I also went down to 03-4B – it's a smallish pitch/rift which looks like it would connect to 03-2B + big, chossy boulders at the top. Once again not at all enticing. Neither 03-7C or 03-6C look to be much.
