Swildon’s Hole and a terminally bad experience in Sump 1 feature in our latest look at caving fiction.
I’ve followed Damian Boyd’s West Country police series on and off over the years but managed to miss out on Death Sentence, which features caving as part of the plot, so I’m grateful to Bob Mehew for reminding me about the book.
Deep underground a woman is attempting to free-dive Sump 1 in Swildon’s Hole for the first time. She’s slightly spooked by her first experience of total darkness when her companion suggests they turn their lights off, but she’s determined to give the sump a go, so she takes a deep breath, grabs the rope firmly and starts to pull herself through. To her horror, no matter how hard she pulls on the rope, she can’t get through, so she tries to wriggle backwards, but that doesn’t work either. She’s stuck and can’t go forward or backwards. She tries to hold her breath, but she can’t hold it forever and she knows she’s going to die …
The dramatic opening will send a shiver down the neck of anyone who has free-dived a sump or thought of doing so, and Boyd captures the horror of the woman’s death well, although a four-hour trip to Sump 1 and back seems a tad on the slow side. But perhaps that, and the change of the ladder climb from 20 to 30 feet, is designed to deter non-cavers from venturing underground. There’s an upside to that change as well, as Bob commented to me – if anyone does decide to take a look for themselves based on Boyd’s description, at least they’ll have the right length of ladder with them.
The opening sequence takes some time to tie into the rest of the book. The main story starts with DI Nick Dixon being called out to look at the dead body of an elderly man in a long-abandoned World War II pillbox. He’s curious about some powder found in the man’s nostrils, which make him think murder rather than accident. When no obvious motive or suspects come to mind, Dixon starts delving and uncovers a complex chain of events from the man’s past as a soldier in the Falklands War.
No one in the military is keen to talk to Dixon, but he perseveres and uncovers the complex web of a cover-up that goes back to events during the distant war. These tie in with an action being brought by some servicemen dying of asbestos-related diseases after been ordered to dismantle three radar cabins. When others connected to the lawsuit start dying, Dixon makes a connection with the woman who died in the cave and he starts to look beneath the surface literally as well as metaphorically.
The caving sequences are well described. Boyd has either visited Swildon’s himself, talked extensively to someone who has, or he’s spent time reading Mendip Underground. Despite that, there’s very much an outsider’s perception at work here, and he seems to start from the viewpoint that caves are inherently scary places and builds plenty of tension from that. It’s worth bearing in mind when he goes underground that this is written from the point of view of someone who’s not spent time getting to know the world beneath his feat. The Wessex Cave Club cottage makes a cameo appearance that will be instantly recognisable, but I’m sure the club would approve of call-out details being left on the board of a seemingly occupied cottage.
Boyd always serves up a good police procedural with a strong West Country flavour. Dixon has slight maverick tendencies but these aren’t overplayed, and the baggage he’s carrying from past investigations isn’t too much of a millstone around his next. And he’s kind to dogs. That’s definitely a bonus in a crime novel.

Damage to gates in Derbyshire is risking access to several mines. Photo courtesy of Pete Knight
Earlier this year, Pete Knight, Derbyshire Caving Association’s projects officer published an open letter detailing damage to gates and the consequences including the risk to long term access. Despite this damage has continued, and most recently all the locks on Homebank Chert mine have again been removed.
In an attempt to highlight the problem and hopefully spread awareness and reduce future damage we’ve agreed with Pete we should republish his original letter below, hoping it will reach as wide an audience as possible.
An open letter from Pete Knight, DCA Projects Officer:
Do you explore old mines or are you interested in visiting old mines?
Have you noticed that some sites are locked or secured with a bolt?
There is a very good reason that you should help us to keep these sites secure. Breaking into mines is a sure way of forcing the landowner to seal them up permanently. The DCA is here to help explorers from all backgrounds visit caves and mines, but some sites must be kept gated – not to keep explorers out, but the general public. Access to these sites is easy though, please read on for more details.
Over the last year or two, there has been a noticed increase in the number of entrances to old mines being broken into in the Peak District area. All these sites have ways for explorers to legitimately enter, either with a key, code or adjustable spanner, without breaking and entering (causing criminal damage). There was no need for the gates or locks to be damaged and having a gate that cannot be secured will likely lead to the owner sealing the site up forever and no one getting back down there. The problem with gates being damaged is perhaps linked to a lack of understanding as to why that physical barrier is there and how to go about gaining legitimate access past it. During its existence, the Derbyshire Caving Association has been asked several times to help landowners and some of the large Derbyshire estates make mine sites safe to members of the public, because they are either on CRoW Access Land or close to public rights of way.
Never has the DCA been involved with physically securing a site that has not had a system for explorers to access it put in place, nor has DCA installed any locks on sites unless this is a non-negotiable condition of the landowner allowing anyone to visit. Where a lock, code or bolt is present, it is because it must be that way, or the site will be permanently sealed. A landowner has a legal obligation to make old mines safe from public entry. This requirement is something that the DCA works with landowners to achieve without resorting to the permanent sealing of the site. If mine gates or shaft lids are not kept closed and secure, a landowner may seal the site permanently, and this has happened many times in the past. Having a gate on a mine does not mean you cannot go down there, it just means that the gate must remain in place and the mine be secure from public entry.
If you are new to caving, mine exploration or have just found this document to read by accident, you might not know about the DCA and its work. DCA is not a governing body, or the cave police, but a collection of cavers and mine explorers who (as volunteers) help landowners and cavers manage cave and mine access, conservation and safety issues. When we are asked to help a landowner install a physical barrier to a mine, it is with explorers in mind that we approach the task. Our intention is always to install the least restrictive access that a landowner is satisfied with. Ultimately, it is their land and they have legal obligations to keep places secure from accidental entry. Our physical securing methods fall into broadly three categories:
No locking mechanism, but a barrier to accidental entry of humans or animals.
This might be as simple as a metal sheet or grill over a shaft or adit. All that is needed is to remove the grill and replace as you go in. Most common for sites on farm land that are away from public rights of way. Please replace all lids to prevent animals from falling into shafts.
A “Derbyshire Key” system.
If you have no idea what this is, it is simply what we locally call a large, adjustable spanner. There are dozens of mine shaft lids and adit doors that are opened and closed just with a spanner. Either use the spanner to remove or loosen a nut or, in some cases, use the spanner to be the handle on a square pin, just like a door handle. We use this system in any locations that have a chance of public access or where there are children at risk if the site is not secured with a tool. Please make sure these gates and lids are always tight shut when you leave, and most gates will allow you to secure yourself inside while exploring. DCA has managed in the past to get some sites with padlocks converted to this spanner system and it is becoming more common around the UK. Buy an adjustable spanner for your kit and the world is your oyster. This system only works for landowners if explorers secure the gate again after use.
If for some reason a Derbyshire Key is not possible to install, or seen as unacceptable by the landowner, there needs to be a padlock installed. Where this is the case, a combination lock is preferably installed on the mine and the combination is issued to anyone who asks for it via the DCA. If the combination is not held by us, then we have details of who to contact on the DCA website. So long as the combinations do not end up posted publicly all over the internet, they will remain unchanged and freely available to those who ask for them. There are three or four sites in Derbyshire that have a padlock that requires an actual key to be used, and that is a condition of the landowner due to either the environmentally sensitive nature of the location, or the extreme proximity to the public or their own property.
In all three examples above, there is no need to break into a site as a tool or code can be obtained with very little delay. All that is required is for you to check up on what you need to get in before you go to a mine and for you to leave the site secure after you go and report any damage to locks or gates to DCA so they can be fixed.
In recent weeks the following sites have been broken into and I use them as an example of how this was totally unnecessary and puts the site at risk from total loss:
Mandale Mine near Lathkill Dale
A Derbyshire Key system used to be in place here. Explorers were regularly leaving the gate undone and the Reserve staff were concerned as this gate is right next to a footpath. DCA was told it had to use a padlock from then on. The padlock was broken off several times. In order to make it easier to get in the mine, DCA then fitted a combination lock, which was also repeatedly cut off. The combination was freely available to those who asked DCA for it. For one last time, DCA will attempt to install a Derbyshire Key system here, but if this is left insecure, as often as the other entrance nearby, the Reserve staff will likely concrete the mine shut forever. This site is at real risk of being lost to all, because an individual or a group of explorers could not be bothered to just tighten a nut back up or email DCA for a code. We have reason to believe it is the same individual or group damaging the locks here and anyone who knows who is responsible is encouraged to give them a copy of this document to read.
Holmebank Mine near Bakewell
One of the two landowners covering the mine workings was upset about regular break-ins to the entrances on their land and has since closed access to the parts of the mine under their land. This has caused the loss of the only wheelchair accessible mine for young people on outdoor centre trips and the loss of a cave diving training venue. Explorers had easy access to this mine for years with no problems until the locks began getting broken off. The landowner of the other half of the mine is constantly replacing combination locks. The combination has always been available for any explorers with insurance by speaking to the owner at his business premises which is right at the mine entrance. Access could not be more straightforward here and the risk of total loss is very real if the gates do not get left secure.
Devonshire Mine near Matlock Bath
For years there was only access to a single gated adit on this land. An adjustable spanner was all that was required. Following the change in landowner a couple of years ago, DCA volunteers capped an open mine shaft in their garden and were rewarded with permission to open other entrances on the land, so long as they were also made secure against entry by their kids and the general public. Recently, the old top entrance has had its rusty steel blockage cut out and a new gate with combination lock fitted (with a view to making it a Derbyshire Key in the future). Anyone can get this combination by requesting it from the DCA. This gate has been complete for just weeks and has already been vandalised. If this gate is not left locked, it will need to be welded shut or be concreted shut and we will lose all access to any of the current or yet unopened entrances to the mine. Stupid actions with the gates at this site will only cost access to the whole mine. The landowner’s house overlooks this site so any entrance left unsecure will be noticed very quickly. DCA volunteers will continue to make these entrances safe again until the landowner has enough and concretes the mine shut.
If you are reading this as someone who either has, or is contemplated breaking into a site, please understand that your doing so has a big impact on all the other explorers who want to go to that mine. In leaving a mine with a lid or door open or breaking in so that it cannot be secured again, these individuals are putting the access to these sites at risk for everyone. A landowner who grants access to a mine, so long as it is left secure, does so because they choose to. They can just as easily have a place permanently sealed up and then they have no more issues with explorers or liability. The point I am making here is that if you find a barrier between you and the mine you wish to visit, either return with a spanner or contact the DCA Access Team to get the combination code. Breaking in and leaving a site unsecured may well cause the loss of that entrance or entire mine permanently. A bit of pre-planning or reading on the internet will give you all the info you need about how to legitimately access a mine site without committing a criminal offence or jeopardising access and years of hard work by volunteers.
No one here at DCA wants to prevent people from going underground, we are only helping the landowner administer the access system they insist on. It is that or no access at all in some cases. Keep gates secure and we’ll keep access to these sites for explorers in the future.
The reasons for the recent increase in damage to gates is hard to pin down. Break-ins have always been a problem, just never this frequently. It may well have something to do with the increased appeal of these old industrial sites to different user groups or the large volume of mine exploring videos appearing on social media. “Urban explorers”, for want of a better description, are explorers just like us cavers, but they may not be aware of DCA and why a site needs to be kept secured and how to go about getting in legitimately. If this message can be spread far and wide it might just save another mine being lost to explorers, or another volunteer having to go out and fix a lock or gate. As explorers, we should also consider what is sensible to put out there on the internet for all to see. Ask yourself is the site sensitive, open or at risk of damage? Should you use a mine’s name or show a location in your social media? We are all entitled to post pictures and videos of the places we go, but please consider the audience you might attract to a mine or cave and, most importantly, the long-term protection of the site itself.

Mike Bedford talks about cave radios, cave communications and much more in the annual report of the BCRA’s Cave Radio and Electronics Group.
Our decision, a few years ago, to broaden our remit to cover other areas of cave technology than our initial emphasis on communications and electronics has been evident during 2018. In one sense, therefore, the name Cave Radio and Electronics Group (CREG) is now something of an unfortunate legacy, because it potentially deters cavers to whom we have plenty to offer. With this in mind, one of the main messages we’d like to communicate is that those who have never been involved with CREG in the past might be pleasantly surprised at what we have to offer, even if they don’t consider themselves electronics enthusiasts.
Over the year in question, in our quarterly publication – the CREG journal – and at our twice-yearly field meetings, we’ve highlighted technologies that are of interest to a broad section of the caving community. What’s more, although we do publish the occasional highly technical article in CREGJ, many of the articles are very much practical and down-to-earth.
Our twice-yearly field meetings continue to be an important part of the CREG calendar and are well attended. It’s encouraging to note that, while we continue to see several old faces, new people commonly attend these events and are often pleasantly surprised at the range of activities, and recognise the potential application to general caving.
Our first meeting in 2018 was at Snailbeach Mine in Shropshire – a new location for CREG – in April, where we were hosted by members of the Shropshire Caving & Mining Club. It was interesting to see some of the encouraging work in cave communication that has been carried out by those SCMC members who don’t normally attend CREG events in other parts of the country. The new Micro Heyphone was on display, and we had the opportunity to see it working in geology that’s different from the usual limestone. Other communications-related tests involved the use of digital voice transmission, which potentially offers benefits over the usual analogue methods, and a demonstration of passing photographs from underground to the surface via cave radio using a smartphone app.

Exploratory work was also carried out into the use of VLF and HF radio for cave communications instead of the usual LF. Beyond communications, we saw a demonstration of bat detectors and loggers, a LoRaWAN gateway (Long Range Wide Area Network) that has potential for data real-time data logging in caves that are remote from mobile phone networks, radiolocation, and continuous LED illumination, as an alternative to flashguns, for cave photography.
We met in the autumn in the Yorkshire Dales for our second meeting of the year. On this occasion, primarily because of the interests of those attending, the emphasis was almost entirely on communication. However, it’s important not to forget the importance of communications in rescue operations and expeditions, while also recognising that, although current equipment provides good service, it doesn’t always perform well in all environments. Improvements to the Micro HeyPhone, aimed at reducing the listener fatigue caused by high levels of interference, were put through their paces. Meanwhile, further tests with HF cave radio – traditionally considered unsuitable for transmitting through the earth – also shows potential and, in particular, was hampered much less by interference than the conventional cave radios used at the same location.

The CREG Journal – which reached issue 104 by the end of 2018 – continues to be published four times a year. It’s encouraging that we’ve had several new contributors this year who recognise the worth of this unique publication in presenting their work to the global caving community. What’s more, this increasing and diverse pool of authors continues to broaden the range of subjects that we are able to cover.
The contents of all issues of CREGJ can be seen here. However, the following provides a brief summary of what we’ve published during 2018 to provide some indication of the rich diversity of our content. Articles have covered batteries and power supplies, cave monitoring and data logging, radio-location, cave communication, cave detection, electronic construction skills, cave exploration with drones, photography and cave-proofing.

We trust that this report has demonstrated that CREG provides a valuable resource for all cavers, whether they’re interested in technology, or even just want to benefit from what technology has to offer to cavers. We remain convinced that subscribing to the CREG journal could benefit all cavers, yet it costs only £4 for four issues of the online edition, which we offer alongside the printed edition. This subscription also provides online access to all back issues. We also believe that many cavers would find our regular field meetings to be enjoyable and interesting, and they’d be very welcome, whether or not they subscribe to the CREG journal. In closing, we should mention the CREG Announce mailing list, which allows subscribers to learn more about CREG’s publications and activities, and the CREG Forum, which provides anyone with the opportunity to ask technical questions or enter into discussions about cave technology.
Report compiled by Mike Bedford of the Cave Radio and Electronics Group (CREG)
With Jon, Nick and Tav.
The Cold Gnarly North was my destination today, the others decided
to dig in the Soft South, which is the easier, more comfortable option.
Drag line attached, bags attached, drill tube and wire reel in
hand I set off along the passage north. I was a bit surprised to find that
there were two puddles of standing water, 50mm – 75mm depth, in the ‘lake’ but
it wasn’t an issue. My plan was to widen the next constriction just beyond the small
rift to improve access and make digging and spoil removal easier. Drilled 4no. holes,
550mm, length x 12mm, diameter and charged. I looked around for “Trevor’s ball
of tamp” that I had put to one side for safe keeping, but it had gone, added to
the spoil heap I assume. Unfortunately, this is probably the only part of the
cave where there is not any mud suitable for tamp. I had to make do with arisings
and the little bit of mud that I could scrape up.
All done, I made my way south, dragging/shoving by bags and kit
along the passage while reeling out the wire. At the junction, the ‘Soft Southerners’
were about finished digging, just the hauling out and emptying of bags to be
done, so I gave them a helping hand. About 70 bags were hauled to the surface
and emptied. When the bags were all empty, I returned underground to bring my
morning’s task to a satisfactory conclusion.
Then down the hill to the farm in the warm sunshine, changed and
up the hill to the Hunter’s for refreshments.
