Great Stoney Traverse Trip Report

This is the story of the (as far as we are aware) fifth ever crossing of the Great Stoney Traverse from Milldam Mine to Stoney Middleton – the longest through trip in the Peak District. I have also created a video of our trip that goes into a bit more detail about the history which can be found here:

That’s enough faff, onto the tale:

Halfway down Lancaster Hole at NCHECC our resident DJ starts trying to convince me to come on a “trip of a lifetime” when we get back on Monday. The trip, as he described it, was a 7.8km through trip starting in a 2024 mine and travelling back in time to some point in the mid 1700s. It would consist of a little bit of trespass, two sketchy mine collapse crossings, a terrifying traverse, some unstable ladders, and a short swim. Ben spent the rest of NCHECC convincing me how sketchy this trip would be, eager to earn some hard caver points I agree to join.

The Monday morning arrives, I hand my last will and testimony to my flatmate and depart for a layby near the TSG hut. Upon arrival I am greeted by Merryn, another member of our five-person party and, an adequate caving delay later, Ben arrives with Daniel and Jack, the final members of the team. We change into our wetsuits and oversuits and pack tackle sacks. We then embark on the 10-ish minute drive from where my car is parked at the exit of the system, to the entrance. It is only at this point that it hit me just how long this trip will be.

Arriving at the entrance to Milldam Mine, we park a short distance away and run from the car down a farm track, keeping low to avoid being seen by the farmhouse. In an attempt to keep people like us out, the entrance shaft had been closed up by a series of metal scraps with small gaps between them. Many people would have given up at this point, but we are cavers, and tight gaps are our forte. One gap just wide enough for us to squeeze through, Merryn and I go in first before Ben makes his attempt. As he is halfway through the squeeze, struggling to get his natural insulation through, we hear a quadbike engine. The two of us already in the mine exchange a worried glance and bolt down into the mine to hide in a dugout in the wall. We wait tensed, hoping Ben and the others make it through before the farmers arrive.

Thankfully everyone gets in with no issues and we carry on the jog until we are confident that we cannot be seen from the surface. We then spent some time stomping through passages large enough to fit a lorry down, exploring the remanence of a mine that shut less than a year ago. We saw break rooms with expired powdered milk, dump trucks, pools of radioactive-looking green water, radon sensor stations, first aid points, ladder shafts, and many other bits, all the while getting in depth explanations on what they were from Ben and heading towards Black Engine escape shaft.

Our path is blocked by some of the green water, Bwn just stomps on through but the rest of us hesitate considering what health effects could come from submerging our lower halves. After clearing the water pools, we make it to Mushroom Gorge, a fault supported by steel trusses and wooden boards with clumps of Last-Of-Us-esque mycelium sprouting from them. A short walk from Mushroom Gorge leads to the gate between Mildam and Ladywash.

Ladywash was characterised by black sooty walls, rail tracks, and a strong scent of diesel. Ben advised us not to touch anything and to walk in the waterways to avoid kicking up dust. The floor went from solid rock to sand and silt, intermittently splashed with bright red, yellows and oranges. A short mix of wading and walking later we came to collapse one. Ben goes first, shouting back the encouraging advice “don’t touch anything,” and the rest of us follow one by one. We continue, now wading, through the passages and junctions towards collapse two.

Once again, Ben goes first, taking a route over some unstable rocks. I’m next, and he suggests a different route below and around. I glance down the suggested passage which consists of a short squeeze under the unstable rubble Ben has just clambered over and a climb round the back. I follow Ben’s route.

Once everyone is through, we climb up some shale and sand piles to approach the traverse that has been hyped up the whole trip. This turns out to be a slight disappointment. Its “terrifying height” is no more than 8 or 9 meters, and it is probably only the same in length. While there are not many footholds, it is quite easy to brace between the two walls, and the foot holds that do exist are sturdy. We all make it across with no issues. I can, however, imagine that before Ben re-bolted this traverse it would have been terrifying.

The next obstacle immediately followed. A very sketchy downclimb over a collapse that was filled with rubble and scrap metal. While I waited for the others to get down, I had a quick bite to eat and changed GoPro Batteries, we were not even halfway so I was going to need to be more conservative with video from here. Finally, it was my turn. I clambered down over the first section of rubble using the knots in the rope as grip. The knots ran out just as the climb became super sketchy. I used a crab from my cowstails to tie a munter and abseil over the worst bit, but as I did this my footing slid slightly, dislodging a huge metal pipe above my head. It fell about 6 inches before settling again and made me seriously question my decision making coming here. It had been smooth sailing up to collapse one, but now it was getting scary.

Safely down, and now in Glebe Mine, we could continue along Crème Brulee Passage, so called because of its orangey sand and water with a crisp red sheet on top. I agree with previous trip reports here – it definitely knocked a few years off each of our lives. Thankfully it did led to some incredible passages that were filled with old mining equipment, pumps and minecarts. These passages seemed to go on for miles, and were filled waist high with water, making the going quite tough and tiring. Eventually though, they did end, and we were free to engage our final two obstacles.

We climbed through a little hole in a wall and then and other little hole in a little grate which led to a third little hole in some rock that opened into a not-so-little ladder shaft. The genius who designed this ladder shaft had put the first ladder on one side of the wall and the other ladder on the wall opposite, with a lovely (just out of reach for anyone under 6’4”) stretch over a roughly 15m drop between the two. Thankfully there was a traverse line rigged between the two wobbly ladders. While Ben and I are waiting at the top of the ladder he informs me that the ‘short swim’ he had advertised was in fact 2 kilometres long. I had been annoyed by how hot and sweaty my wetsuit had made me in the three hours leading up to this point but hearing this I was very glad I was wearing it.

The bottom of the ladder opened straight out into the swim, which turned out to be my favourite part of the trip. It led through stone lined passages that varied from knee high stooped wading to swimming with your head turned sideways to fit in the airgap. I found the best way to pass vast sections of this was to hold onto a tackle sack being dragged by another team member and just float down the stream. After about an hour of swimming and wading, Ben announces we are three quarters of the way there. Another 15-20 minutes of the same and he corrects himself – we are now actually three quarters of the way.

The final stretch of the swim was a sensual nightmare. Tight crawly passages, with only your head out the water (which has been mudded up by those ahead of you so you cannot see what you are touching), and roots, lots and lots of slimy roots - brushing past your face and sides, with your hands and knees sinking into the spindly mess of them on the bottom of the passage. Grim. Thankfully this was the final stretch. A manhole cover above our heads showed we were back at surface level, and eventually we popped out into someone’s garden. A short stomach shuffle up another streamway under their garden wall and we are out on the side of the road.

We dried off, collected the car from where we left it by the entrance 10 minutes up the road, and ended with the obligatory pub discussion of the day’s events. An absolutely incredible trip, it took 4.5 hours total. While it was not quite as death defying as described, it was most certainly still some hard caving. I would really recommend to anyone who likes mines and swimming. If you do want to talk to do the crossing talk to Ben or those at EPC, I have heard rumours of a route description in the works.
 
Myself, the mine manager Rob Ridley, Nick Hardy and others.
I wrote a report (which i still have) slides too, however the company wouldn't let me publish them because of public liability in a working mine.
 
@T pot 2 I guess the '96 traverse would've gone straight through the main drag (pre collapse)? Rather than the oxbow/traverse in the stope? The level has a name which I can't for the life of me remember (I have Old Hay or something similar)... There's a plaque which you only see when doing the trip in reverse which warns miner's about entering another mine.

Yes we indeed go through the mine ventilation fan housing into the main drag then on to ladywash visiting the wet west, loco battery charging house, fitting and electrcians shops, the winch house down to sub one, up the main level to the bottom of ladywood shaft and beyond. Then to the boil up at glebe where in the event of flood the loco's would be lifted above the flood zone.
Onto the bottom of glebe mineshaft to look up to daylight, back to metal grill seperating glebe and moorwood sough, down the metal ladder and into the sough proper.
Going with the flow of the cold water we plodded on until we came the Victory level, on reaching its end and made our way back to the sough and out to Stoney Middleton brook. Total trip hours 9.5.
As an aside i assisted in the removal of the Glebe mine headstocks while the site was cleared. I also fabricated and installed the metal shaft cap that seals the top of Ladywash mine, if you happen to visit you may see my name and date welded into the metal ( T pot 1981 ).

Awesome video! Whenever I try record underground you can only see around 3m in front. Any tips?
The camera I was using (DJI Osmo Action 4) had a low light mode that worked really well. If you are shooting on one without that you can try bumping the shutter speed down, this may make the image a little less crisp as it will include a bit more motion blur but could be worth the trade off. You can also bump up the ISO but this will add noise to the image. Best bet is probably just a much brighter torch!
 
Unfortunately I don't think this trip will be possible again at-least for a while, the main adit entrance has been completely walled up, because of metal thiefs going in and pulling wires down (and the roof). It's a pity as we only got as far as scouting probbably half way (as far as the roped traverse and never got to do the traverse). The other entrance which involves a 90m pitch I believe the landowner would cut your ropes so that's out too.
 
I think it's 105m. The landowner let us go down a few times circa 2011-13, but I'm not sure of the current situation.

I was talking to Dave Shearsmith about this the other day and he mentioned that they do open up Milldam main entrance once a month so the trip could still be possible if you time it right/ask the landowner's permission.
 
Aye its properly walled now, not just blocks half way up anymore. The landowner used to move the blocks to let people in I believe if arranged through the right people, but the metal thieves were the "last straw" in the landowners words, so it is properly walled it up, that and council had been apparently demanding that he secures it, "for safety".

I am sure if someone talked to both the council and landowner maybe a secure Derbyshire gate compromise could be installed funded by cavers, but that's up to the DCA to deal with I guess. I assume he would also want proof of liability insurance too.

P.s. how do you get in via Cussy? I thought the only other entrance is the other end of the through trip in the vicarage, also difficult considering you sneaking through someone's garden I believe.

I think the final straw for the owner was that he blocked an opening in the adit gate that the metal thieves had made resulting in a party of 6 explorers being "trapped", when he returned later in the day he had to let the 6 guys out. The owner was concerned about being held accountable if anyone got injured, that and people damaging his property.

Cliffstile Mine also drops you into the sough, further upstream - halfway to Glebe Mine in fact. But it is a deep shaft, so would require jugging back out again at the end if that route was used.

I've been in and out several times via the sough tail, and never sneaked through anybody's garden, but I think it was probably always 'arranged' - not by me though, which is why I'm being a bit vague. But it is possible - and really good fun going through all the tree roots :)

I have no idea whether an access agreement for the adit could be set up via DCA, but I'm guessing it might be problematic - not least as the mine closed so recently (and rather controversially), so all the hazards (and arguments) are well-known and documented, as opposed to guessed at, or 'beyond living memory', as most long-abandoned mines are. Sallet Hole still has ex-workers around, as will Middleton Mine, Long Rake (Youlgreave), etc.

Plus there's all the legal bullshit which I'm sure is still ongoing behind the scenes, with mineral rights, compo (or not) for the surface collapses, royalties, etc. I'm no legal expert, but I suspect BCA PL insurance in this context may be seen as a bit flimsy, and not fit for purpose. And obviously offers zero protection to cavers for personal risk, which would probably be classed as 'considerable' by the same legal experts.

I think given there at least five other 'legal' entrances into the system, that range from 'no access issues' to 'definitely needs arranging with the landowner', it's best to focus on those for now, and see how things develop over the long-term. The villagers of Great Hucklow also need to be considered too, as it is all literally on their doorstep.
