Intake Dale Mine

Discussions following on from the Bradwell Catchment Symposium and after reading reports from the 80's of natural rift and chambers, EPC members have re-descended Intake Dale Mine and embarked on exploring it further.

 Intake Dale Main Chamber

Since opening up the engine shaft back in June, getting a proper lid sorted and installed has been firmly on the "to do" list. The Eldon are therefore extremely grateful to have recently had one of the best traditional metal workers in the world join the clan. Hal Debes, with his apprentice young Dylan, work at Portobello Engineering and over the summer have put some of their skills to work on the task. Lockdowns and Cussey momentarily took attention away from Intake Dale, but in November the new lid was bolted into place and a good few whiskies enjoyed to celebrate the moment (or crappy lager if you’re a Dylan). 

And oh boy, what a lid!

The site was later cleared of the scaffold tripod and all the crap that was hauled out of the shaft. All that now awaits is the finishing off of the walling around the lid front, which the DCA have again volunteered to do once the weather improved (supposedly due to the mortar curing temperature, but we all know the real reason). As with Cussey, a large Derbyshire key is required to open the lid, however curious visitors are asked to hold off until the lid walling is made good.

(Luke Cafferty & Jon Pemberton)

Just Luke and I tonight adhering to the law, we met for pre-beers at the usual layby and discussed the housing market, general chit-chat led to our target for this evening – heading back to Isolation which we discovered on 19th March 2020 just days before the first lockdown (see previous trip report). Our plan was to rig the entrance and connect it with the westward extensions rope, armed with drill, ropes and a ruck of bolts we made our way across to the entrance.

Both keen to get underground as it was freezing up top I took a quick leak only to break the zip on my over-suit (completely unzipped) – buggery, a catastrophic failure! Hal & Dylan’s lid on the entrance is truly one of the best lids in Derbyshire only to be surrounded by a great mound of stacked boulders including steps – top work to all involved (we can’t take much credit as we just dug a hole… typical TA.)

I rigged the entrance and abseiled down, the rope only needed re-tying into the existing anchors leading up to the westward extensions and didn’t warrant any more bolts. I got to a safe place and hollered Luke down. I then guided Luke through the next few sections to the TAP Room (you kind'a forget how much dodgy stuff is in here, I can see why Dave didn’t want to come back.) Once in the TAP Room we reshuffled the bag and dumped a rope, I told Luke how rubbish the next part was with Rob’s shady rigging – he wasn’t surprised. We headed along TAP Traverse pointing out to Luke the T’owd man’s footprints, we abseiled down at the end and were only 2mins away from Isolation, a simple traverse led by an awkward thrutch to a dodgy thrutch over a tight hole (probably wants a rope) leads to a climb down into a funnel of boulders and dodgy stacked dead’s to a slot in the floor – this leads to Isolation.

FINALLY!!! – after 6 months of dreaming, not being cave fit this trip had already felt like a slog! Once Luke was through the slot I quickly started rigging the pitch we had left behind all those months ago. I backed it up as the rock sounded dreadfully hollow and the back-up made for a good anchor in the traverse line too. The pitch was 8m deep and had a very natural feel to it. East the passage headed off into a large boulder choke underneath the Isolation chamber with a mud filled rift heading off North (no draught). A squeeze between boulders and a loose back wall led into an extension of the cartgate as seen before the Isolation traverse. This continued for 20m or so heading through solution pockets and largely covered in mud (obviously floods) to a forefield, a choked shaft heads up on the northerly side but no ways forward. I exited this section with great care as I didn’t want the whole choke running in when I was here on my own.

Once back up the pitch we de-rigged and ran a traverse to the opposite side, here we dumped the drill and most of our SRT gear and progressed fast and light heading deep into the hillside. The first obstacle was a small squeeze at floor level through tailings. This led to a loose climb which belled out above me but what was stranger still was I seemed to be looking up through a perfectly round hole in a solid floor some 6m above, the workings above us must be quite extensive. Back at floor level a further squeeze at floor level led to a choked section but looking through boulders in front it looked and sounded pretty big and the black space between boulders was a dead giveaway. Luke joined me in the passage and once out of the way I pushed a climb up and over between more loose dead’s, here I could drop over beyond the choke and was gob smacked by what was in front of me…

I was in a large flat roofed bedding chamber with a solid wall on my right, to the left the chamber was approx. 6m as far as I could tell but this was blocked by a humongous slab which had detached from the roof. What made this more impressive was that the slab was some 1m deep and probably the size of my driveway threatening to flatten anyone who comes near it – WAIT did I not mention it appears to be held up by hopes and dreams? Actually a little book sized nodule from what I could see. I waited in awe for Luke to arrive so that I could see his face and reaction thus we came up with the name - Stop Flattening Me!

From here on we vaguely looked at the leads which were popping up everywhere. There was most definitely at least one higher level above us if not more. Walking around the back of the slab a big black space could be seen down a gravel slope. Luke dug his way through whilst I admired the massive scallops covering the roof. He made the entrance big enough to slide through and shouted me through. We were now stood up in the continuation of the large natural stream-way seen in the eastern extensions of the cave but it was short lived and continued through to a larger chamber with a blocked continuation which’d need digging. The air movement down in this place was dead and we made our way back to the slope which was a lot trickier to exit from but not before having a quick look at the downstream continuation which seems to be lost under the large collapse from the chamber (again not inspected properly).

We discussed turning around at this point and thought to do a quick scout to make sure the main level (running parallel to the natural below) didn’t suddenly crap out. A small slope led to a wider section where all of a sudden the draught appeared again and the air felt a bit more breathable. Looking above use were extensive workings and levels heading off in both directions. Carrying on west the main level rose again blocked by a some stacking and a backfill of tailings which will require a little dig to gain access to but completely open beyond. We also noticed a potential mined passage heading north some 5m above us although this could just be a solution cavity.

Here’s where we turned around, baffled by the place and rather exhausted we knew there was some way to go before we reached the surface so started plodding on out. Luke was not a happy bunny by the end of TAP Traverse and once on surface we were bitterly cold within seconds due to the crystal clear night and a view to Mars. Someone had walked by the entrance whilst we were underground and opened the lid – any takers? Also it’s a longer ascent than you think back up the engine shaft from the Westward Extensions!

Cold and defeated we didn’t fancy a post beer and decided to bugger off home for warmth instead.

Another memorable one for the books.

It’s been over three months since me and Jon walked into Lockdown and both our minds are very much still there. However due to the government’s restrictions on playtime plus the extra spicy nature of the hanging death at the far end of IDM (well, all of it actually) we’ve felt it best not to return yet as rescue implications at the moment would be very regrettable embarrassing.

In the meantime we’ve located the engine shaft on the surface and spent a couple evenings digging it open. What was first sold as a 1.4m deep project soon became a +5m deep dig, but now Derbyshire has itself another fine 70m freehanging mineshaft to add to the portfolio. Since then over a few weeks the DCA have done some mighty fine pointing up of the top 5m or so of the engine shaft walls, making it look far too appealing a place for the average caver!

   

In the meantime aspirant members Hal and Dylan have been working out ways of securing their place in the legend filled halls of the mighty EPC and so have put their metal fabrication skills to use with making up a lid. Last night the first part of this was expertly welded into place and they only have to finish the top part (and pay their subs next year) before they are welcomed in as equals.

 

A massive advantage of the engine shaft entrance is that it cuts out ~40 minutes of loose and tiresome caving in each direction, including the dodgy Blackjack Choke. Hopefully this alone will be enough to allow the team to feel it ok to keep pushing west in hope of glory and medals? Watch this space…

With the increasing spread of Covid 19 activities underground have finished for the foreseeable. This is additionally frustrating with leaving such a wide open lead at the bottom of Intake Dale Mine, but at least that gives the team something to be dreaming about whilst stuck at home

This break has given the team the chance to update the drawn survey, albeit it still very much work in progress with large parts awaiting being surveyed including a large section of the cartgate and the impressive Isolation. The survey so far can be downloaded from the Club's open survey page:

Again only Rob and I on tonight’s exploits and what a trip to miss!

You know when something snowballs or spirals out of control? That’s what we’re kind of dealing with on the exploration side at the moment in Intake Dale Mine. Each week just keeps getting longer, more technical, harder work, loads more “fuck-whittery” & definitely more dangerous… and silly. So here’s what happened this week…

We supped our usual pre-beers at the normal time and again after deciding on what gear we’d be taking down we made quick work of kitting up and the walk down the dale. The evening was warm in comparison to previous weeks and no gloves, balaclava or strategically placing of vehicle were required to keep warm whilst kitting up. Knowing from last week that prospects at the bottom were pretty slim with the continuation of the Cartgate ending at a collapse we had already planned to attack the obvious traverse in the roof just below The Tap Room. Having been given  some shiny new 60m of 9mm to destroy (thanks to Roy Rodgers) we decided this would be perfect to tackle the project along with the dinky Bosch Uneo drill and a few more bolts and anchors we were well equipped for an adventure.

We reached Tap Room after 30 min from the entrance then after sorting gear Rob took the lead and we both dropped down to the small ledge just below the funnel of deads.  Rob started edging west whilst I belayed him from my makeshift belay, turns out we had fewer bolts than we thought so we spared the one at the bottom of the funnel and tied into the rope hanging down from The Tap Room.

Rob edged west for about 6m to where the rift widened to about 1m wide which made jamming oneself in this space rather awkward. He placed a bolt for mild protection then made his way into the unknown. He shouted back in amazement with his now crystal clear view of the 20+ stemple ladder we gawped at from below last week. He proclaimed that he needed to ascend between stemples to what he thought was a safe ledge to proceed forward. After a bit of moaning and groaning he got himself to the ledge, placed a bolt and was ready to belay me across.

Obviously I had the harder task in seconding the traverse loaded with the survey gear on my side… I started across and once at the bolt re-tied it so we could have a fixed traverse on the way back. At this point we were now free-hanging some 100ft above where we had walked the previous week at the bottom of The Big Rift. Now I was at the tricky part, where the rift widened. The surveying gear made it hard work with it bunching up on one side, I dropped into the rift proper and the sides were slicked with mud. Rob had actually made a half decent job of pushing this on very sparse runners but he didn’t have the surveying gear… After making a meal of the job I listened to Rob’s advice and just let myself fall on the rope. Here I now pulled myself across the traverse like a sloth on a branch and soon found myself at The “Stemple Highway” now named “TAP Traverse”. Rob told me off for wanting to try the stemples and see if they’d hold my weight.

Here we were now comfortably standing with a solid roof above our heads. Rob was WHOOPING away telling me to look forward. In front of us, still heading west was a perfect ledge system on both sides with a perfectly placed row of six stemples. It’s safe to say the next section of traverse was easy pickings. I belayed Rob on the off chance he’d slip trying to dodge the T’owd Man’s clog prints along these ledges. They’d obviously done the exact same thing we were now doing some 200 years before us. After a further 10m we reached a point where the ledges ran out and after another easy bridge where some water ran in from above Rob placed another one of our precious bolts and shouted me across after he hard-rigged the traverse.

Where the ledge ran out the roof stepped up for 5m to two higher levels heading East and West, East looked very inviting, walking height and quite wide with a small stream emerging from it but was the obvious harder option to reach (avoiding stemples) whilst West was an easy bridge, also with a small trickle of water flowing out and the lead I thought carried the draught!

Ok what do we do now?

We had two options based on our limited gear. We had about 30m of rope left but only 2 more bolts. We could either head upwards here and check out these two leads (most likely continuing upwards and to surface) or proceed on the traverse west and see how far we get. We chose West as it looked easy going for the time being and we’d be able to make good progress and extend the survey to yet another sheet of paper. After the bolt a tight, awkward traverse led to a false calcited floor which took weight. After another thrutch and some more stemple dodging Rob placed our second to last bolt just before a large opening which began to appear in front of us.

Here the rift opened up all around it looks like a large section of the north wall had collapsed leaving some large bonnet sized pieces of rock jammed down below us and further in front which left a large open space at our height. Rob was excited as he thought we were still with the draught. Upwards continued out of sight, West continued after a wide traverse and below was a large drop but we were unsure if we’d advanced from last week’s limit. Rob checked out the traverse and after a quick inspection he thought it was doable without much protection. He bridged the wide gap and after 5m and a bit more fuck-whittery he found himself safely on the other side. What was now coming back didn’t sound great. The continuation west tightened up and it looks like our efforts to proceed west had finished for tonight!

We obviously couldn’t progress up here with our last remaining bolt so our next option was to descend from the last bolt as far as the rope would take us as we’d nearly ran out and then see where abouts we were in comparison to last week then survey back out to The Tap Room. Rob re-rigged the hang and slowly descended dodging the false floor and stemples around him. He laughed at what I was standing on as he could see from below how thick the floor was or wasn’t! Good job I was safely clipped in. Rob reached the floor and once clear gave me a big, “ROPE FREE!” I wasted no time in following him down the rope which now made for a quick descent I had to use a cow’s tail as a braking crab to give me a bit more friction on the new 9mm. About halfway down looked a good spot to continue our traverse west but this would have to wait for more bolts (now on 4 leads and counting).

Once at the bottom Rob shouted over the not so good news that we were back in the climbing section above the end of the Cartgate from last week. Good in a sense that we could now tie in the survey and see exactly how far west the final collapse was but bad in the sense that this was it. We climbed back down to the final collapse and whilst Rob started to shoot splays in the final collapsed, muddy chamber I took a few photos of the wooden ladder we’d forgot to do last week. We climbed back up to the head of the small ginged shaft to where a higher traverse headed west along a ledge. We looked at this last week and thought nah! – looks shit, better off going higher up. Rob said he’d already been across so far and it was wank, normally Rob’s good at this sort of stuff too but not this time.

 I went for a second look and after a few metres there was no indication he pushed beyond. I crawled along the ledge to where I could stand up. From here a tight bridge across a small pot gained access to a rubble slope, here I could see the way on west continued after a further ascending bridge cum traverse over a 4m deep pot. The way over west looked large in comparison and I could feel a draught. The pot below looked natural, it reminded me of one of the small fractured pots at the bottom of Nettle Pot. At the bottom of the pot a small black hole caught my eye, I shouted back to Rob that it looked good and that I was going to climb down and check it out. Rob soon crawled his way along the ledge so he could see what was going on. The pot was really sketchy with both the west and east wall sides stacked way above our heads, we had to make sure not to touch anything close by.

At the bottom of the pot I could see through the hole into a small chamber until my view went out of sight. I couldn’t see much but I could feel the strong draught coming out which is strange as we’ve been following the draught throughout the rest of the mine – Boy! It was now getting exciting again. Rob climbed down as we had plenty of space at the bottom for both of us. I encouraged him to dig the floor whilst I filmed it on my camera. After removing a shit ton of rock which fell straight through into the chamber below we now had before us a rubble slope between two solid walls which dropped down 1.5m into the chamber below. Rob dropped through and as quickly as he’d disappeared out of sight he shouted to come through – QUICK! I dithered about and dropped my camera case and as quickly as possible dropped down the slope.

I was now sat on a boulder floor looking at Rob who was staring down a large natural passage heading north – ISOLATION! We’d cracked it or so I thought! After a bit of WHOOPING and a high five Rob encouraged me to push north along the passage, it was a large collapsed passage with a vadose trench carved through the centre. The passage was very muddy and looked to be a prime contender for the source of the flooding. After a few metres the passage soon filled with mud and although there was still a small airspace present it carried no draught – bugger!

Back in the chamber I dug a few boulders from the rubble floor which seemed quite open but we proceeded west to where a small natural passage entered from the south but was filled with mud. Before us now still heading west the roof shot up showing signs of miner’s activity, we were now back in miner’s territory (up here appears to link back to the passage going west at the top of the pot). We were now stood at the head of a 7m pitch in solid rock. We could see a solid floor but the way on looked to maybe be underneath us. I could hear somewhere in the distance a faint dripping falling into a pool just as I could hear back when we first explored The Hobgoblin’s Hideaway. We were now faced with the biggest dilemma of the evening.

I was keen to push on forward as we could easily traverse the pitch and continue west out of sight but Rob with his serious head on for the first time was the voice of reason. We came to an agreement and decided to head back to where we stopped surveying and continue to survey back up to The Tap Room. This would leave us hungry to come back after the pandemic had subsided but also gave us important survey data that we needed to start drawing up The Big Rift. Once back at last survey station we giddily surveyed back out, up the pitch and along the traverse whilst taking photos along the way. We both agreed that the traverse required a few more bolts for the feint hearted ( Lukey Boy) and we’d be probably be better off pushing the very end by abseiling down a lot closer to The Tap Room and walking along the bottom.

We reached the surface just before midnight and enjoyed a couple of Hobgoblin’s in the car whilst WHOOPING a few more times at what a spectacular, Awesome evening we’d just had and at what could possibly be the end of the world – hence why we didn’t try make the pub due to spread of Corona virus. – Hence calling our natural discovery ISOLATION.

We now have 6 leads to look at when we return but the first job will be to continue the survey to Isolation first, shame this’ll have to wait a few weeks if not months before we get the gang back together and push onwards through what’ll surely become known as The Wild West.

Stay safe kids.
