In Search of The Northern Lights, OFD2 – August 20th 2017

We were getting close to our destination now, the Northern Lights in Ogof Fynnon Ddu2. We were three members of Brynmawr Caving Club, Myself, Rob and Mick, and had got to a point where there was a squeeze up through a dug out section over boulders and under a low section of roof. Mick and I had slithered into the comfortable standing space beyond and were watching as Rob tried to get through. Unfortunately Rob’s efforts were coming to nothing, “It’s my chest” he groaned as he tried a different contortion. “Try moving over a bit” we helpfully suggested, “Or on your back,” but, try as he might, Rob wasn’t going to be seeing the Northern Lights that day. I had visited there on a couple of occasions and Rob and Mick were yet to see this impressive part of the system. We made a quick decision that we’d stick together as a team and retreat as one. After all, Rob could lose a bit of weight and the next time we’d be sure to get through. Life has a habit of getting in the way and I ended working the other side of the country, Rob moved away and tragically, we lost Mick at far too young an age and so it was, that return to The Northern Lights with a slimmed-down Rob was never made.
It’s now August 2017 and after the passing of nearly twenty years, I have grown a bit older, a bit greyer and also a bit outwards, but am still enjoying trips into many of the South Wales caves. Tom, a young whippersnapper caver, and I were trying to decide where we would go at the weekend. I suggested OFD and thought that I detected him mumbling something about ‘showcaves.’ “How dare he?” I thought to myself and so suggested that we should visit somewhere a bit off of the usual tourist routes and head for The Northern Lights in OFD2. I quoted the description from to him “That is accessed through a rather complicated and sporting route” and so it was settled. It was agreed that we would head for the Northern Lights but that bearing in mind that I had a hazy memory of it being a difficult place to find, that we’d be happy with just heading to that part of the cave with the intention of getting to know the area better.
On the day we were joined by Vicky and Zeb for the long walk up the track to the entrance. Luckily, we weren’t too far from the cottages when I asked who had the survey. Blank looks all round meant that they’d been left somewhere other than with us. “I gave them to you when we were filling in the ticket” said Vicky cheerfully as this meant that she could abrogate all responsibility and it was down to me to walk back and pick them up where she’d left them. So, I placed my Pelicase with containing the ‘F—ing camera’ as it was known to some and hurried back. At least now I could claim to have travelled further than even Young Whippersnapper Tom and have a reasonable excuse for being knackered later. So, I ambled back to where they were sitting with curious smirks on their faces, retrieved my Pelicase and we were off up the hill again.
The entrance was soon reached and as everyone was adjusting their kit, I produced my camera announcing that we had to do the obligatory selfie. I’d been sure to charge my camera as I love taking photographs of trips to record the experience. Many will inevitably turn out to be ‘crap’ but even these are valuable memories to be stored for later years. So, it was with a puzzled face that I looked at my camera as it failed to turn on. Repeated pressing of the power button gave nothing and I wondered if it had frozen so opened the battery compartment to remove the battery and reset it. The empty battery compartment induced a sense of shock, horror and bewilderment which gave way to comprehension as I connected the missing battery with the smirks seen early. “Okay give it back” and a few choice words resulted in my battery being sheepishly returned. I must admit to losing it slightly, there are some things people shouldn’t mess with, redheads, The Zohan, other people’s wives, and a photographer’s camera(I like to think I can call myself one). Now it was my turn to look sheepish as I got my way with the selfie and we opened the gate and entered the cool dark of the cave..

Obligatory Selfie

The plan was to head through The Brickyard to Gnome Passage and then The Wedding Cake. From here we’d head down Salubrious and a quick viewing of The Trident and The Judge before on to The Crossroads and the beautiful Selenite Tunnel, Shatter Pillar and then sort of find our way from there relying on the surveys and my memory.
It was soon apparent that someone was having oversuit trouble as it had obviously ‘shrunk’ causing some trouble when needing to climb in the Brickyard. No worries though, we carried on and were soon out and in Gnome Passage and turning into the passage that leads to the Wedding Cake. A short stop to admire this formation and, as usual, wondering who would want a cake like this for their wedding. It would be more accurate to call it the Wedding Splat. Young Whippersnapper Tom was eager to get going and led off down Salubrious and I followed. The odd little tearing sound as we clambered over boulders seemed to indicate that the oversuit situation was gradually resolving itself and we turned off for another short stop at The Trident. I was getting twitchy at this point as I hadn’t taken any photographs, this wasn’t normal. The camera was in the Pelicase instead of my inner oversuit pocket so it couldn’t be whipped out so easily. I had taken some pictures of the Judge and Trident last time I was here but was not happy with them and want to have another go with a bit more thought to the lighting. This wasn’t going to be the time though as we were off again to The Crossroads, across President’s Leap with me again telling myself that I shall have to find out why it is called that one day. In Selenite Tunnel I was allowed to take a photo and shot a couple of Vicky looking down the passage.

After this, we headed to Shatter Pillar and headed down where we had a choice of passages on the survey, the ‘straight way’ and the ‘wiggly way’ as we called them. We chose the ‘straight way’ which we followed to Cross Rift where more boulder clambering brought us to Mignight Passage and then into the top of Midnight Chamber.
We were running late by this point, we’d dawdled a bit and along with getting into the cave an hour late we loitered in Midnight Chamber and pondered where to go now. Someone did mention something about a nice pint of ale in the Briton but we weren’t going to head out yet. It was decided that the elite team of Young Whippersnapper Tom and Zeb The Snake would head off toward the Northern Lights with the survey and some vague recollections from me. These amounted to the squeeze where Rob got stuck, a longish ascending squeeze into the start of the Northern Lights and an ascending tube to be climbed. “Nothing too bad though” I said.
As the others headed off, Vicky and I went for a look down Midnight Passage. It’s not an unpleasant passage and you can soon hear the streamway up ahead. Pausing to take photos, we soon had used up half our alloted time and retraced our steps back to Midnight Chamber to find our intrepid explorers moaning about squalid crawls and water, “I really don’t remember any of that” I said. “Anyway, I want to try out my bulb firer” and produced a strange contraption that I’d made up from an old bulb firer and some spare wire. Vicky was placed at the end out of sight and Tom was told to stand in an ‘epic’ sort of way. “3, 2, 1 fire!” And there was light, lots of light, it worked!
Midnight Chamber
By now, the pub was calling and we headed off. Tom and I had a quick look up the passage that goes off below Frozen River and then we returned back via ‘Wiggly Way’ where we were surprised by some nice helectites and crystals on the walls along with a band of some fine fossils.
Wiggly Way HelectitesWiggly Way Fossils

The rest of the way was uneventful and was pretty much the inward trip in reverse until we emerged back into the outside again and back down the hill to change and a welcome pint in the Ancient Briton.

I don’t think I will ever tire of Ogof Fynnon Ddu, there are always places to go and new things to see in there. It just needs you to head off of the tourist routes and have a look down the small passages on the survey that you’d never bother with usually.
Young Whippersnapper Tom is keen for a visit to the end of OFD3, somewhere I’ve never been to yet. I think I should add it to the list.

Daren Cilau to Ogof Cnwc Through Trip – 13th August 2017 by Trig

Early start for this one as we had wanted leave a lot of time for route finding, with a belly full of bacon sarnies I set off for , The weather being a bit too nice for the 500m plus of crawling about to ensue. As I get to Abergavenny Tom texts to say his car key is in the washing machine so there will be a slight delay!
We meet in the car park and discuss whether maybe getting a key to OFD would be a more sensible option or even a wander in Dan Yr Ogof showcave. But after a nice cup of “Man Up” we find ourselves at the start of the entrance crawl.

Slithering into the icy waters the swear words could have probably be heard in Aggy but once we both negotiated The Vice the going eased off and normal conversation was had and pictures taken and plenty of “not as bad as I remember” remarks were said. We cleared the entrance in about an hour, stopping only for a drink and a couple of snaps.

One thing that annoys me about Daren is how the entrance just stops and you are suddenly in walking passage! God send really. We didn’t hang about and pressed on, Tom hadn’t seen the crystal pool before so we decided to go and have a quick look in there before Jigsaw, as its pretty much en route. Worth noting this part of the cave is quite easy for navigating as there are handy reflectors pointing you in the direction of Jigsaw Passage and vice versa for the Entrance/Exit. After a picture of the dried up Crystal Pool we pushed on into Jigsaw Passage and through The Wriggle.

Arriving at the logbook in ‘Big Chamber Nowhere Near The Entrance’ we signed the log book and consulted the survey. We both had been in the cave both and Tom had done the route before, but in reverse and we all know how different caves look in the opposite direction so this was going to be a good old fashioned survey and description following kind of trip. We carried on as per description but took several attempts and a compass reading! to find ‘Epocalypse Way’

Now this is when I started to realise what an amazing place this is, as after only a few minutes in the easy going walking chamber on the left hand side in the far distance something catches your eye…..a pure white glow. The pace increases to reach the famous formation of ‘White Company’. Can easily say it was breath taking and well worth the few hours of caving to reach such an epic. We stayed here for a short while taking pictures and having a rest and generally taking in such a sight for sore eyes.

Continuing on still impressed with White Company we are rewarded once again with a short climb into a very very very well decorated oxbow, ‘Urchin Oxbow’ to be exact with its deposits and crystal lined roof and yet again another reason to side-track from the planned route. Just round the corner from Urchin the aptly named ‘Kitchen’ is found, where we stopped for lunch and refilled water bottles with some of Llangatwgs finest council pop.

Now turning left and then left again we appeared in ‘Antler Passage’ and yet again the cave reveals another one of its secrets in the form of a gorgeous set of Helictites named ‘The Antlers’ (for obvious reasons). Now here comes (in my opinion!) the hardest part of the trip. Antler Passage is long….really long and its 99.8% boulder hopping up and down boulder slopes of which this mountain and its systems are famous for with the remaining 0.2% being awkward small pitches with ladders and lines in situ with one being rather tight at the top where I managed to sub humanly bend my knee in un-godly directions. Its easily to navigate funnily enough as its one long passage with ‘Man in the Roof’ dropping back into the passage at one point. But it does eventually end in the form of a lovely wet boulder choke and another climb……..decent.

Popping out into ‘Busman’s Holiday’ here our survey improved somewhat and route finding was relatively easy until we reached ‘Prices Prophecy’ which is an amazing, well decorated chamber where the way on looks to the right ( I have previously read about some guys a few years previous who took this route and never found the connection with Cnwc and had to turn back and travel the full 4-5hours back through Daren!) but is actually off to the left into a further decorated chamber and low behold a helpful sign reading “Cwnc exit this way!” too easy!
What else can I say about Cnwc…it’s a dig, it’s not hard but it certainly isn’t pleasant but certainly beats having to go all the way back. We exit covered in mud but high, very high spirits into the warm summers day. Back in the car park we entertain some holiday makers with our tales of crawls and endless passages much to their amusement.
Definitely one of my favourite caves and trips of all times and I think Tom would agree!

Bridge Cave – 4th July 2017

Vyvyan and Bevita

Two of Tom’s work colleagues had expressed an interest in seeing what this caving lark is all about and so we agreed to take them to Bridge Cave for an evening trip.

Bridge Cave is relatively short but has a large and impressive stream passage as well as some formations. It is part of the larger Little Neath River Cave system that was originally discovered by divers when they passed the sump at the end of the cave.

We all met up at the car park near Blan Nedd Isaf farm and paid our parking fee before changing and heading off to the cave. Another nice feature of this cave is the very short walk, a hop over the style and it’s just around the corner.

The cave starts out a ‘bit crawly’ and leads to the small boulder choke where it isn’t a good idea to stop and ponder how long the bit of wood has been there holding it up before dropping down and through a narrow bit into the stream where you then shortly pop out into the large stream passage.

None of this fazed Vyvyan or Bevita and they were soon admiring what Bridge Cave has to offer. I’m not sure what they expected, maybe a lot of crawling and mud but were very pleasantly surprised at just how nice this caving thing could be.

We spent a good while exploring the stream passage, heading down the side passage where Tom explained where the water comes from and then down to the end and under the bridge, the span of rock that has been left from the cave formation and which gives the cave its name. The sump was visited and the formations admired while Tom crawled off to have a closer look at the sump whilst Huw and I explained where the sump leads and how caves and formations are formed.

After Tom rejoined us we climbed up by the bridge to view the grotto that can be found there before heading back upstream and out of the cave.

Vyvyan and Brevita definitely enjoyed the trip and I hope that they will join us again sometime soon.

OFD1 – Main Streamway – 2nd April 2017 by Barry Burn

A somewhat poignant trip for me as this was to be Rob’s last caving trip before leaving South Wales for a life of retirement sailing the ocean’s and visiting far-off shores.

Rob and Myself along with Mark Wedlock were a regular team that explored a lot of the underground world of South Wales back in the 90s and early 2000s, but sadly, events transpired so that we gradually stopped caving together. Rob has now retired and is planning to whisk Paulyne, his wife, off on a life of mad adventure sailing the globe. But, before that, he wanted one last caving trip and especially one into OFD1 that he hadn’t visited for quite a few years.

A fine spring morning saw us meeting up at Penwyllt. Rob’s daughter Ruby joined us for her first taste of OFD and along with Dione and Trig we made our way to the layby where we changed and headed off to the entrance.There had been a fair bit of rain recently so the streamway promised to be sporting but we decided to carry on and to see how things looked when we reached The Step.

We had soon all descended the ladder and re-grouped in the small chamber at the bottom and then headed off into the cave. Ruby’s experience up until then had been much smaller caves with Porth yr Ogof being the biggest and so this was a suitably impressive step-up for her and she was obviously enjoying herself as the cave passage got progressively larger and better decorated. Rob, went into some sort of dreamlike state reminiscing about previous through-trips and we swapped tales about trips into the far reaches of OFD2 and other caves as well as fun times such as when nearly all of GCRT (us included) became trapped on the wrong side of a collapse.

A few photos on the way and we were soon at the calcite climb up into Column Passage and Trig kindly obliged to climb up first to rig a hand line. All were soon up and then along the passage to the small chamber that contains The Column where a fair bit of time was spent admiring it and trying to get Ruby and Dione to lead the way on to Eagle’s Nest through the duck. After is was clear that there was a sad lack of gullibility on this trip, we headed back and down the climb with varying amounts of grace.A few photos on the way and we were soon at the calcite climb up into Column Passage and Trig kindly obliged to climb up first to rig a hand line.

At The Step the streamway was indeed slightly sporting, but just enough to make it more fun than the usual sploshing upstream, and so entered the water and progressed upstream. Everyone was more than eager to head off as some caring soul had decided that the passage just before The Step was a great place to relieve oneself and the stink of stale urine was overpowering here.

Heading upstream with more photos and a short diversion up to the start of the Maypole Wire and then a stop for a short break in Boulder Chamber before heading back downstream. Climbing out at The Step, we sent a few helmet-fulls of water onto the rock in a hope of cleaning it up a bit.

An obligatory visit to the passage beyond Pluto’s Bath and then back to the entrance. Trig and I went for a quick look at Gothic Sump before we headed back into the open air.

A shortish trip, but thoroughly enjoyable. It was great to be caving again and hopefully Rob’s travels will bring him back to Wales in the not too distant future and maybe then we can drag Mark back underground again. Ruby professed to having enjoyed the cave and was keen to see more so I hope she’ll continue the way she’s started and join us on some more trips.

So this would be my first trip into this cave, I’d never really thought much about it until I joined Brynmawr and heard a lot about it so I was pretty keen to do this trip. Tom suggested a generous call out time so we could really see the most and reach the end where it is, oh so close, to the beast of Daren Cilau next door.

The day started by meeting  Tom and Adrian in Asda car park nice and early where I followed them to the car park (layby) to start the age old caving discipline of getting naked in car parks. After a quick ‘’before’’ shot we were off  to the entrance and after a quick faff with the gate we were in and straight away greeted with formations and straws! Through the first boulder choke, up the ladder we went and into a fun wet crawl (well I found it fun as my tackle sack *ahem* floated quite nicely behind me) which took minimal effort.


We reached a junction and I was shown the famous ‘’North West Inlet’’ where we decided that could wait for a hot summers evening maybe. Continuing on, we approached two small pitches. One with a ladder and the other with a fixed handline but feeling slightly exposed at the top. This led straight onto the lovely 2nd Choke. Now this choke was slightly uncomfortable as it climbs and winds upwards but safe in the knowledge that  it could only be easier on the exit we pretty much flew up it.

Our heads poked out of the choke one by one like meerkats….relieved meerkats and we pushed on into ‘’Travertine Passage’’ with its stunning Travertine Dams and formations. Stunning place! But the best was yet to come as next was ‘’The Hall of  The Mountain Kings’’…..WOW what a place, I’d seen this in various books but nothing could prepare me for this place. Thank god for modern cap lamps which helped illuminate this place that day!

After a quick drink and the usual non-caving chat, we set off again to the right through the 3rd choke and on to ‘’Severn Tunnel’’ a nice crawl where at one point many a larger caver has not been able to continue. This uncomfortable passage turns into stooping after 200-250m or so. Here my memory is failing me and all I can remember now is being at a large junction with boulder choke 5 and the pitch down into Promised Land. We dropped the bags off at this point and spent considerable time looking for possible leads which there is no doubt but just need finding or effort. We also went to visit the famous ‘’Helictite Passage’’ a stunning  little passage but with amazing formations where only 2 cavers are allowed at once, now this is why this cave was so strictly controlled in its earlier days.

After a lot of admiration we carried on back to collect the bags and onto the pitch down into Promised Land where we met a small stream. The way on is right but we turned left to go and admire yet another formation in this cave, ‘’The Pagoda’’. Back on track we made good progress hopping boulder to boulder and then turning right we entered an oxbow from the stream which had a few crawls and chokes to overcome before re-joining the stream. We carry on gaining momentum and then suddenly it ends. If only there could be a way on into Daren. We have a breather and drink/food and do the honest thing of turning around to go home to our families to treat them all with our muddy smiles and bruised bodies!

The way out is un-eventful and the 2nd Boulder choke is a breeze with gravity on your side.

In summary its certainly is a highly decorated cave and certainly can provide a good days caving. I cannot wait to return hopefully by the end of the year. No pictures underground sadly.

5 or 6 hours underground…I think.

Having sampled most of what OFD1 has to offer, I needed to get back to OFD2 and start to re-discover the delights that the more complex part of this system presents. So, it was that Tom and I were joined by Nick, an old member of Isca who was returning to caving after a long break.

Meeting at Penwyllt we soon discovered that opting for a trip on a CHECC weekend has it’s own problems with the huge numbers of hung-over students that were milling around looking for their trip leaders. At one point, Tom and I were examining the survey in the common room when we heard a subtle groan and discovered a comatose male student looking up at us and wondering where in the seven circles he had found himself. We offered to show him an eighth one but he just cuddled up under his blanket and tried hard to ignore us.

Tom was on his second trip into the system that weekend having helped out with leading hordes of students around the OFD2 system the day before. He was at pains to point out that technically he’d actually done 1 and a half trips as on exiting the cave with one group, he’d been grabbed, before he could escape out of the entrance, to help show another group around. He pointed out that this was the reason for the state of his kit, although I personally couldn’t see the difference from a normal trip.

The three of us did the usual trudge up the hill, Tom dripping mud, whilst Nick and I looked more respectable alongside him (although Nick was glowing slightly in his nice new oversuit), to the OFD2 entrance. A pause for a selfie and we were off into the relative warmth of cave.

We were soon heading past Big Chamber Near The Entrance and via The Brickyard into Gnome Passage. The plan was to do one of the trade routes down Salubrious and then via Selenite Tunnel to Edward’s Shortcut and then back into Gnome Passage before heading out.

We were soon at The Wedding Cake that is more of a splat, perhaps it should be rename the Wedding Cake Smash. We headed up Chasm Passage for a look at The Chasm before retracing our path back to the start of Salubrious Streamway.

There was a group of students in front of us when we reached the Corkscrew so we waited to allow them to get ahead.

We soon caught up with them though and they asked for directions to the Trident and Judge. We’d borrowed a copy of the old survey and using this we gave them what we thought were the correct directions. Thinking we’d let them get ahead, we decided to go past the junction and have a look around before coming back to for a look ourselves. However, we soon found ourselves at The Trident and realising that the survey may have lied, Tom went back to get them on the right path whilst Nick and I stayed to take some photographs.

Tom reappeared with the students in tow and they were suitably impressed with the formations although none of them seemed able to ‘see’ the Judge. They soon left back up Salubrious and we headed in the other direction to see Selenite Tunnel.

We now just needed to head back to Gnome Passage via Shatter Pillar and then into Edward’s Shortcut. The climb up at the end of this has always been a slippery awkward climb but since I was there last, it seems to have become a really slippery awkward bastard of a climb. However, we were soon up and then back in Gnome Passage then back out the way we had come into the cold, sleety outside for a chilly walk back down the hill.

OFD1 – A Wee Potter Around – 20th November 2016 by Barry Burn

Barry Burn
Adam Knapp

With a view to visiting the Railton-Wilde series in OFD1, Adam and I met up bright and early at Penwyllt after a period of heavy snow the night before and reviewed the plan for the day. Overnight, there had been a heavy fall of snow with significant accumulations that were now melting. This would mean that there would be a large amount of water that would have entered the system and it was possible that there would be an additional input somewhere that would result in water levels rising again or further. We decided to write out the ticket to indicate an intention to visit the series but also to have a general bimble around the Fault Series and other areas of OFD1.

The OFD system is a marvelous place that I don’t think I’ll ever tire of visiting. There are always other places to find and explore. In 2016, I enjoyed becoming very well acquainted with OFD1 and in 2017, I think I shall reacquaint myself with OFD2. there are some places there I may never see but I would like to get to know this extensive system and revisit some of the lesser visited places such as the Northern Lights that I haven’t seen for a good many years. But for this day, it was OFD1 again.

Driving down to the lay-by and changing, we were soon off down the lane and up to the entrance. A quick selfie (I still can’t get these right) and we were down through the gate just in front of a group of SWCC prospective members that were visiting OFD for their first time.

We quickly moved off into the cave to reach the Toastrack and then on to The Step. Here it was obvious that there had been a significant amount of water that had entered the system and the stream level was quite high. Not the highest I have seen but high enough to potentially give some problems. At this point the following group turned up to have a look and the leader decided that it would be better to take her acolytes into some of the upper series instead and they returned the way they had come. Adam and I stepped into the stream to see if it would be passable and found the stream to be over well over knee level. We found it was relatively easy moving against the current but turning around it was obvious that this is where the potential problems could lie. Without a lot of concentration, it would be easy to lose one’s footing especially when descending the small cascades and water chutes that are in the streamway. We felt that if the water levels were dropping that we would be okay, however, it wasn’t known if there was further snowmelt still entering the system potentially increasing the water levels further. So, deciding it was likely to be a geological age before the Railton-Wilde series went  anywhere, we entered into bimble mode.

We made our way back the way we had come stopping for the odd photograph and looking into most of the small series that can be found around that area such as the Upper Toastrack and Coral Pool series. We then headed back towards the Fault Series with the intention of finding a passage that we thought we missed last time, stopping on the way to have a long chat with a couple of SWCC members.

A quick visit to the stream again by traversing over Pluto’s Bath for a lunch stop and another couple of photos and then we headed off and were soon climbing up into the Fault Series. We found the missing passage but it was taped off and weren’t going to be able to visit it anyway and so contented ourselves with another visit to the previously visited passage and a look at the formations there.

We were soon back on the surface for another selfie (I’m getting better) after a shorter than intended but still thoroughly enjoyable wee potter around OFD1.

(Please note, photographs to be added later).

OCAF – North West Inlet 13th Sept 2016 by Barry Burn

A short evening trip into North West Inlet (NWI) was decided upon although I wasn’t sure if I would be home from work in time for it. There was to be the full compliment but various childcare issues meant that the ones lucky enough to have children old enough to look after themselves were the only ones able to make it.

Meeting at the layby by UB40 and jumping out of the car made me pause. There was something odd and strange, something was different, then it struck me, tarmac! The layby had been given a very nice new surface that replaced the horrible mud and discarded rubbish.

We were quickly changed and off up the path to the OCAF entrance. Dione, our newest member hadn’t been into OCAF before and was keen to see what we had been waxing so lyrical about.

The North West Inlet trip is (or was) an often overlooked trip that takes you through a very wet approach passage just before the pitches up to the Second Choke. This passage, although never taking you out of your depth (unless very short) will get you very wet as you wade neck deep in places. It soon, however, rises up and leads to a short muddy section and then gets bigger and higher as you follow the streamway. Formations abound, with one of the best being “The Dragon” but also plenty of flowstone and stalctites are to be seen.

There is a bit where you have to drop through boulders to continue and here it was sad to see that people had tried to go past the tapes and the obvious marks in the mud the other side of the route through the boulder bore witness to this. It does make me wonder how stupid people can be to not be able to follow an obvious taped path.

Continuing on brings you to the end of the passage and the dig that John Parker and Jeff Hill pushed for a long time, installing a railway with miniature wagons for the removal of spoil. The dig itself is rather unstable now with some collapses within but I often wonder what the indefatigable OCAF diggers would have found if they’d continued.

A look at the railway and the formations at the end of the passage and we were soon on our way back out and at the cars getting changed.

Judging by Dione’s mad grin that seemed to now be a permanent fixture, I think she enjoyed herself and is now ready for a foray beyond the Second Choke and having already been into Nant Rhin, I have no doubt she will find it a piece of cake.

After a long but pleasant walk from Penwllyt, we were finally at the entrance to Pant Mawr Pot. Huw went down to rig while myself, Malcolm and Helen kitted up and I had one last bite to eat.

Abseiling down in a daylight shaft for a first time made me a bit nervous. All my other abseils have been into darkness, meaning I couldn’t see how far I could potentially fall and lulling myself into a false sense of security. This one was different, being able to clearly see the bottom, seeing how far down Huw and Helen were, really put into perspective how deep I was about to go. What followed was a period of swearing, panicking and holding onto the rope for dear life before I was onto the boulders at the rebelay. Helen made it look so easy, I made a right mess of it. The actual abseil was rather fun, albeit short lived. And before I knew it, I was at the bottom.

It felt like we had left 2016 behind and had stepped back into Jurassic Park. The sound of a waterfall in the distance, ferns high above us and a shaft of bright light piercing the darkness. This is what caving is about! Many a frog had somehow managed the journey from the surface without injury, there seemed to be a thriving colony in the underworld. A newt(?) was a pleasant surprise, I think it’s the first one I’ve ever seen in the wild. After a bit of photography, we started to move downstream, passing the first and second chokes with relative ease. Stopping off at Straw Chamber and the stunningly decorated Chaple, the helictites growing from the walls were a highlight. Travelling down through the oxbow, we arrived at Sabre Junction with the very impressive Sabre shaped formation from which the section is named. There is a rope hanging down from a climb just to the left of the Sabre, but due to the apparent age of the rope we decided against it. Later examination of the original 1959 survey doesn’t make reference to a high level passage there. Onwards through the third choke and a well earned pit stop. A number of small cairns in the area, some very impressively balanced, were the topic of conversation. But we couldn’t decide why they had been built. Next was The Graveyard, which links with The Vestry and The Organ Loft. Huw, Helen and I went off to investigate but shortly returned without seeing them. Next was The Great Hall and The Fire Hydrant, the force and volume of water from which was very impressive. A junction was then met, on the left was The Dead End and to the right the passage continued onwards towards The Sump. Malcolm went to look at the digs and abandoned digging materials, while Huw, Helen and I went to the sump and back. Much fun was had in the slippy mud en route. The fresh looking foam on the roof of the passages gave an indication of the heigh of the recent flooding in the passages. After taking stock of the digging debris left at The Dead End digs, we made quick progress back upstream and to the waterfall upstream of the entrance pitch. Huw made an impressive climb to then appear at the top of the waterfall. We washed our kit in the waterfall and decided to head home. I was looking forward to climbing back up the pitch, only to realise that I’d set my footloop a few inches too short. This made for difficult, tiring and slow progress back to the pitch head. I did get out…..eventually.

All in all a good trip, I wouldn’t mind a return trip to have a look at the higher level parts of the cave, above Sabre junction and into Dilly’s Despair.

OFD1 – The Fault Series – by Barry Burn

4th September 2016

A short trip into OFD1 for a bit of a bimble up to the Fault Series and a poke around some of the other passages that are generally ignored by the majority of visitors.

There was supposed to be six of us but that had become three by the time we set off in the morning and it was only Tris and me from Brynmawr that met up with Adam from Morgannwg at Penwyllt bright and early.

There had been torrential rain the night before and we had to fend off a number of advisories to keep out of the streamway. I explained that we weren’t that daft and were only planning on a trip to The Fault Series. I did want to have a look at the Main Streamway though so intended to get close to it and see what state it was in.

We did our usual thing of driving the cars down to the layby to change where I discovered that instead of just forgetting my towel or clean undies, I’d managed to forget everything bar my oversuit, hat and lamp. “Ah well” I said, “It’s a dry trip, we’re going to be keeping out of the water” and so off we went with me less cosy than usual. We were soon into the cave and made our way to the start of The Fault Series that is a high level passage reached by climbing up a steep flowstone ramp. It was here that I remembered the unwritten rule of caving that every dry trip will always have a spot where you get wet. There was a lot of water flowing down the calcite ramp and at the top, there is a climb up through boulders where there was enough water cascading into it to give me a good wetting down.

The Fault Series itself is short but well worth the visit. There are some nice formations as well as some unusual mud formations. The whole area is well taped to protect these and they must be observed or the area would soon be trashed.

The passage after the mud deposits becomes larger until progress is halted at a large choke that hasn’t yet been passed. As we had plenty of time, we lingered awhile taking photos before returning back down the calcite ramp.


Getting a good soaking coming back through the boulder squeeze.

We decided to have a look at the streamway at The Step so headed off there to be impressed with the torrent that was flowing. It would be definitely sporting to have tried to go upstream that day. Some foam flecks far above the current stream level showed that it had been considerably higher quite recently.p9040631

Instead of climbing back up The Step, there is a short section of passage, marked on the survey as Loopways so we had a quick look down there. This ends at a drop to the streamway but it is worth the quick look. In Traverse Passage, there is a window that looks down onto this short passage.


A look up the start of the Escape Route and then coming back down the Toastrack, Tris and Adam decided to go through Pluto’s Bath and down to the streamway again. I was feeling the cold by now and didn’t fancy a dunking so elected to stay put. I soon heard calls that I really should come on down and see something. I was able to avoid the water by traversing across Pluto’s Bath and headed down the passage. The lower end of the passage was covered, walls and ceiling in foam and was a stark testament to just how high the Streamway can rise in flood. It must have risen to somewhere around six to eight feet above the current level. At this point is was possible to sit right by the water’s edge without getting swept away and this we did for a while before heading back out stopping briefly for Tris to perform his ‘ablutions.’

Of course, it is almost obligatory to visit the Ancient Briton after a good trip into OFD and so we called in for a swift half on the way home.

p9040672 This was a good fun trip. It was something different, a good easy trip looking into some places in OFD1 that see few visitors. This can be immensely enjoyable and almost therapeutic that allows you to really see the cave and enjoy it rather than rushing headlong to a remote destination for a quick look around and then rushing back. For me, caving is more about exploration and discovery than scoring ticks in the manner of Munro baggers and I always say that more people should slow down and look around them as there is a lot to be seen that is often missed.

Note to self: get your kit ready the day before then you won’t forget anything.
