Trouser Filler to DADES Choke
It is worth noting that, from REU to this point, the passage has trended up-dip through the mountain in a northerly direction, but things are about to change. Take the northerly passage from Trouser Filler and follow it as it trends immediately westwards through a series of small chambers and walking and all-fours crawls. Just before it degenerates to a long, flat out crawl, the Sand Swims, a passage on the right, The Warren, heads north, mainly as a thrutchy crawl, to a 6m pitch up, possibly still rigged with an antiquated ladder (care), through a series of sand-filled chambers whose connecting digs require regular clearing, ending in a lead with spectacular aragonite formations that would be more viable if there was a bit more stacking space without the likelihood of blocking yourself in. Another contender for the southerly continuation or Trident Passage or, further away but well-aligned and similar in nature, Midnight Passage in Agen Allwedd?
You now resume the long see-saw back down the mountain with a tedious, flat out crawl, with one all too brief respite, through the Sand Swims heading due south and, after 100 metres, reach the large passage of Friday the Thirteenth. Ignore a dig up on the left wall, Gwyn’s Surprise, which doubles back to the north before fizzling out, and head down the impressive main passage. Bypass a boulder choke by climbing up and along on the RHS to drop down to the continuation, note an impressive hole up in the roof before eventually coming to a passage on the left, Shit Rift, which continues for over 100 metres, becoming increasingly narrow until impassable to even the slimmest of anorexic cave tigers. Just beyond the start of Shit Rift, in a moderate-sized passage, you arrive at a dug out, sandy u-tube (which needs regular clearing out as sand is carried in by each passing caver) and a banged dig, Another Bloody Valentine, above which a short climb heads up into a bouldery rift with an enticing draught continuing upwards, with spaces between boulders, that may reward a committed siege with a good drill. 5m up the rift a gnarly, constricted, horizontal squeeze past blocks brings you out into Payoff Passage, a parched, crumbly, breakdown passage which is followed, gently downhill, mostly on all fours with several unrelenting constrictions, for about a hundred metres until, just before a short wriggle, a small inlet on the right, Bad Bat, is reached. When it was discovered Bad Bat had a promising draught that was lost, possibly due to spoil being stacked to the sides while digging. Parties on subsequent trips have experienced bad air problems. Bad Bat trends westwards for some way as a low crawl with squeezes, heading close to, but at a higher level than, the extensions beyond Iles Inlet in Agen Allwedd.
Continue south, through the wriggle, along the main passage and pass over a narrow slot, through which stones can be dropped into a tantalizingly out of sight, lower level void, to eventually arrive at the massive boulder choke of DADES (Do Androids Dream of Electric Sheep?) Choke. This is one of the closest points for a connection to Agen Allwedd, and gets to within 35m of Priory Road. A connection has been attempted, and abandoned, from the Agen Allwedd side and would require long-term, committed digging through a large, unstable boulder choke. Regular diggers on the Daren side have hitherto opted to leave the two caves unconnected to preserve the unique nature of this extremely remote section of cave (not to mention the long term siege tactics required for the project!). In the floor nearby is a choked dig, Stingray.
