Redhouse Lane Swallet Update

After a quiet few weeks, we had a busy weekend in Redhouse.

Chocolate river team 4/10/25: Andrew Atkinson and Matt Jones

Aim was the end of chocolate river via the white forest. The end constriction was passed quickly but was immediately mud choked. We dug at another lead in the higher passage in conglomerate layer, where Andrew broke into a small chamber. A small passage continued upwards, with what we thought was a small air-flow, but needed a chisel or something more to help clear the constriction. Wouldn’t say was the most promising..

We then backtracked continuing upwards, where it feels like you’re going back at a high level over chocolate river. Matt squeezed up (tight) with help of lump hammer to reach roof level where the crease limestone meets marl. A junction right in crease went too tight. Possible passage beyond, but solid rock constriction for a few metres.

The other way, following roof ended in flat out marl choke. Maybe 25-30m found in the two locations.

West End trip 4/10/25: Tiff, Pete, Joel, Dan, Gareth and Ian.

Planned to photo + derig the Wild West pitch, dig at the end ‘Crow’ dig and to bolt climb the inlet at the camp.

On the way to the end, Joel climbed the dripping inlet in the gour chamber just before HH. He made it look easy, but unfortunately all too tight at the top, with nothing in the way to digging prospects, so I think we can tick that one off the list.

Gareth, aided by myself, methodically bolt climbed the 7M camp inlet. At the top a few boulders needed gardening and then those with SRT kits pushed into a large aven. (Joel, Tiff and Gareth). They reckon it’s about 17M and 4M wide, with clean washed sides. Great prospects for getting near the surface (maybe below the infilled depression area?) No obvious passages going off – It will need to be bolt climbed and Gareth is very enthused to return.

By this time the other group were finishing off the photos and derigging. Most of us has a dig at the end Crow dig. Ongoing mud floor, we were just worm holing through, stacking to the sides. Tight, but made good progress – probably about 8-10M on the day. We left it with a tantalising wider section about 3 meters ahead, but were running out of stacking space. Definitely worth preserving with as it’s heading straight to the SY cliffs, but probably needs a drag tray system for the next dig. Very fresh in there, so we were all quite excited about the prospects.

All then made are way out – last out by 9.30pm, just to ensure the dubious glory of a 12hour trip!

White Forest trip 5/10/25. Falky, Alex and Ollie.

Planned to do some taping and cleaning around White Forest. Sadly, Falky pulled his back in the entrance series and soon after getting past NIRA decided not to carry on, so he headed back out. Alex and Ollie carried on to White Forest picking up the spray bottle and tape on the way. These were left at the WF and the drill was brought from HH back to WF, so everything is there ready for taping and cleaning next time.

Science trip: 5/10/25. Mark Tringham - Report to follow..

Also, there will soon be another video from our multi award winning videographer, so keep a look out!
 
Crow Dig and Bolt climb: 12/10/25:
A team of 5 visited the West End. Gareth and Ian bolted the 17M aven above the Camp Inlet area, just beyond the Howling Hole. After 4 hours or so, Gareth got near the top, but no good leads were seen. He would like one more trip back, just to finish it off for definite. Meanwhile, Tiff, Joel and Dan went back to the promising Crow End dig, the most Westerly part of the cave. We hoped that 3 hours of digging the mud floor would be enough to get to a wider section we could see. As it turned out, we only needed 2 ½ hours - The new passage was about 1M high and went on for about 25M from the start of the dig, in a Northerly direction. The passage then changed character, turned 90 degrees west and heading off for about another 25M, in smaller, flat out passage. We reached a larger end chamber, with lots of dead flies decomposing and saw a living fly or two. Very excited, we realised we were pretty close to the surface and making the Wye Valley exit a reality..

We decided the priority must be to photo and film the area before any more visits, next to Radio locate the end chamber, to work out exactly where we are on the surface, then get the survey done.


Crow Radio location trip 18/10/25:
What followed was a week of intense planning, trying to get our ducks in a row, co-ordinating the underground and surface teams, ready for the Radio Location trip.

We arrived at 8am and we were met by Craig with all the equipment. The photo and filming crew - Bartek, Loz and Ian set off first, whilst my rag tag crew of Dylan and Dan from Cardiff Uni and Mikey from the BEC, had a quick briefing for the cave link, VHF radios and the radio location equipment from Craig. Next job was to haul it all down to the Crow dig, 4 hours away..

All went smoothly enough on the way there, with the expected gawps from the newbies going through the White Forest. Cave link worked well and we soon had coms with the surface. Always a positive boost when you are long way from home! (The only issue was the surface Boomers trying to understand Gen Z txt spk.. 😉 ) The radio location gear was set up after Bartek and Loz had finished their photos. We had no luck with the VHF radios, but an hour or so after the radio antenna was set up, and Mike relayed messages to me, via cave link, that a surface location spot had been identified. Sitting on my own for over an hour in the end chamber, you start to hear things – mainly the dripping of water, but I thought I could hear faint tapping.. Standing up and putting my head into the hole in the roof, the tapping started to get louder – definitely hammering from above! Very difficult to tell how close, but also very exciting to hear outside noise, this far into the cave.

Talking with the surface crew afterwards, they have pinpointed the location, but the depth reading was tricky due to the terrain (scree slopes and cliffs) Unfortunately, the end chamber had solid walls and it’s not possible to dig from the inside. We think the height difference is about 20M, so it will be a long term project. Surveying will be completed in a couple of weeks and Ian should have a new video out this week!
 
Those helictites in the White Forest are stunning. I'd be scared to approach too closely for fear that a slight air movement would break something.
Fortunately most of the way through is walking away from the helictites and just sensible care is needed to preserve the beauty.

Some water spray is needed on some passing stal which we have in hand.

Sadly due to a persistently stubborn herniated disc I personally can't sort out myself just now but my wonderful colleagues have it all in hand.
 
Just caught up with Ep20. Everything about the series is top quality - on top of the gruelling 12-hour trips, the conservation work and rescue prep, the videography is suberb, including the editing - everything you want to know is there, but pared down to its essence in 7 minutes. Fabulous!

couldn't say it better..... so true
 
In case you haven't yet subscribed, Episode 22 is out.
Underground survey was completed on Sunday during which the surveyors choked from the incense sticks lit above.
Hammering was clearly heard from both sides.
There is a lot of work to do, including securing formal permission for a surface dig. There does appear to be a significant vertical gap and a lot of rock, so it won't be quick win.

 
Trip Report 9-11-25: Dan, Tim, Rhys and Cath to High North

Aim was to finish off the original survey which thankfully we achieved 😊.

High North is a series of interconnecting rifts, some very tight, with lots of blind rifts off, often 3 or 4 at a junction. It is a nightmare to survey, but does have the benefit of lots of loop closures. I admire the Missed Pot team, it must get very tedious surveying a maze cave.

Surveying mostly uneventful, with a further 84m added, making this part of the cave 319m long.

A new draughting dig was found. The end promising dig was left for another day. One loop that had been previously passed by Big Dyl and Joel is still not able to be passed by normal sized people despite a good lot of work by Rhys and a lump hammer - however survey loop was made from each end. Another loop wasn't quite connected large enough for normal sized people which leads to the newer stuff reported earlier, 10 minutes with a crowbar will sort that.

It was my first caving trip in 12 weeks after my back injury and ensuing sciatica. I have been religiously doing physio exercise and open water swimming 5 days a week and the physio said that I should be OK for caving for a short trip! I had read on this forum that crawling was good for their sciatica. I can confirm it doesn't work for everybody! I had a bit of rough time in parts. At the tight rift in High North, I experienced complete pins and needles and numbness down my right leg when forcing through the squeeze, and the back was very uncomfortable coming out. But it was really nice to be back underground again 😊. Feeling it today though:(

A huge thanks to my patient team and fingers crossed for a trip next week.
