Last Plymouth blood



When I got home I suddenly realised I would never see these people again. I had been donating blood in a nearby church, and I always enjoy that: all the people working at the blood bank have always been nice to me. The guy who calls me his stalker, for showing up at practically all of the donating venues, even knows my name, and always comes over to joke around a bit. And in the UK, they won’t let you donate more often than once every four months. It’s January now; by the time I am allowed again it’ll be May! I’ll be moving to York then! I regretted not having said goodbye. I might send a card… and I’ll keep on donating blood up north!

To the beach during working hours


If you want to know what lies under your feet, you can of course try to drill a hole and see what you find. You can also use more modern ways, and use geophysics, such as Ground Penetrating Radar (GPR), to get an idea. But you can also just sit around and wait until erosion strips off the familiar surface layers and grants you a look below. 

About two years ago, anAmerican hydrologist spent his sabbatical in the southwest. He was an oldfriend of Roland, and they worked together on a project that involved hydrological modelling of a coastal valley. They knew there was a 3000 year old peat layer in there somewhere, which made that valley hydrologically interesting. In order to gain input for the model they took cores of the subsurface, and mapped it with GPR. All well so far.

And then the sea stripped all the beach pebbles off of this peat layer. An opportunity not to be missed! Having a look is always more telling than the other, rather indirect ways of perusing. Locals who knew of Rolands interest in this peat contacted him about it, and he wanted to go and see for himself. And survey the whole package in. That’s a task that is best done with more than one person, so he asked me to come along. Prancing around a beach during working hours? Oh well, I’ll sacrifice myself! 

We gathered early at the university’s equipment store, loaded up the differential GPS, and drove over the quiet roads below pink skies and past valleys filled with morning fog to Hallsands. It’s a nice beach I had never visited. And the peat layer was impressive! Red tree stumps were sticking out. I took some pictures while Roland started the assemblage of the DGPS. It had been a while since we had last used it, and it took us forever to get it going; I had trouble getting the tripod exactly above the benchmark (that Roland and his mate had put in earlier), and perfectly level too. Roland struggled with getting the software to work. But we managed! And from then on it was easy: the equipment does the work. Just hit “measure” and go. Which was good; the weather was deteriorating! When we were done Roland tried to download the data in the dryness of the car, and that’s also where we had lunch. It was properly pissing down. In a short dry-ish spell we dissembled the DGPR again, and off we were. By now, all that data has reached the USA! I think that model will improve significantly…



This is how we found Hallsands

It looked a bit less picturesque when we were leaving!

More CSI


“That’s not a proper knot!” We were in Kents Cavern, looking at staged scenes of underground incidents, after having all swooned over the new team Landrover. We had done a few trainings in CSI before; we had practised searching areas for clues while not stomping all over the place and obliterating things such as footprints of suspects, and trying to get an idea of what happened from the clues we found. The thought behind this was that as cavers we might come across crime scenes, either by accident or on request, and we would have to know how to act in such a situation. You might come across some lone caver that slipped somewhere, and fell to his death. That would, of course, be an accident if it happened that way, but an unexpected corpse is always the scene of a potential crime until the police has ruled otherwise. And we sometimes get asked by the police to look out for missing people; it’s not unthinkable a southwestern murderer would dispose of a body underground. 

This evening would be the denouement of these trainings. This time, we had actual police crime scene experts (I suppose they would automatically also be accident scene experts, as it is vital for their work to be able to distinguish between the two) with us, looking at how we managed. Depending on how we performed, they may decide they can leave a body recovery to us, if it for instance involves tricky rope work. I thought the main point was to convince them we would not thrash a potential crime scene, and would indeed find all the clues present, but I came to realise there was more to it – they were there to see what we would see that they didn’t. It’s one thing to know how to put a body in a body bag in a way that preserves all the evidence and excludes the possibility of contamination; it’s another thing to recognise a way of rigging that is not up to standards.  

The first scene we found involved an invisible body in a belay belt, and some rigging. It took some suspense of disbelief to reconstruct what had happened here; the body had fallen to his death, but the ceiling was so low that could in reality hardly have happened. But we figured he had been climbing, attached to a rope in a Y-hang. The Y-hang would consist of a loop in the rope on one side, and of a sling on the other side. It had not been symmetrical, and a fall had landed on the sling, which had snapped. The full force of the fall then landed on the other side of the Y, where a karabiner broke under the sudden jolt. An accident, evidently; but an accident can still be a crime, if it is due to gross negligence. 

We also found someone who had gotten lost underground, and whose light had in the end gone out; he had also gotten cold, hungry and thirsty, and died of exhaustion and hypothermia. And a murder victim that had been dragged in, leaving a trace of lost items and fragments of clothing and whatnot. And another rig, where again a rope had snapped.

The constable we had with us was quite pleased with our performance. He didn’t know enough about rigging to recognise a failed Y-hang, and didn’t know what sort of knot you use for tying a rope around a rock. I think they’ll be in touch when something terrible happens underground! And during the de-brief we were pleased to hear it had taken quite some effort, and two Landrovers, to produce the broken and stretched karabiners… that may be one of the reasons why such incidents as we imagined that day are so rare!

Underground landrover

Should you have a car if you need it about once every two years? Maybe! The Devon Cave rescue Organisation does not get many call-outs, but we make sure we keep our skills honed for in case we are desperately needed one day. So we train every month. And most of these training require stretchers, ropes, resuscitation dolls, underground radios, or whatnot. So somebody has to go to the store and get all that. And if there's a call-out, someone really needs to get to our equipment storage quickly. And it tended to be our practice officer who ended up lugging stuff around in his private car all the time. Not ideal! Buying a team trailer was considered. That at least keeps team and private kit separate. But then we were offered an entire Landrover for much less than a trailer would ever cost... to be precise: for £1. Who could resist that? Yes we've managed fine so far, but sometimes one should seize opportunities. So even though such a car would require a parking space, perhaps lots of maintenance, insurance, and whatnot, thereby making it more expensive than that one quid, we decided we would go for it. And it's cool, too!

It was the Kendal Mountain Rescue Team that needed a new vehicle, and offered us the old one. Behind the scenes, it had been handed over, and give a make-over to make it a proper DCRO car. And now we would be presented with it. We combined this with a training in Kents Cavern; more about that in a later post.

Floodlights were ready for our vehicle to give acte de presence. It arrived with flashing blue lights and siren! We were all very impressed. James Hull of Kents Cavern handed the keys over to our chairman Brian, and then we could all go and admire it. A bit strange they did all that in the shadow of the car; not good for pictures! After the training we did a little photo session on the other side of the Landie, though not all of our members were willing to pose.

If someone now gets into trouble underground somewhere, we can show up with all our kit in less time, and get the casualty out in less time. And with more style! I won't be driving it; they asked for drivers, but I'll be buggering off soon, and I don't have the desired experience in driving 2000kg+ vehicles. But I trust our dear team will have a good time with this new toy!


Admiring glances in the direction of the Landrover


Was it Gandalf who gave a speech? No, our very own Brian, who unfortunately suffered from a back injury.

And this is the beauty!

And we're quite handsome ourselves, come to think of it!

Nietzsche and Kant read the newspaper

It rhymes, and therefore it is true! What rhymes? The book title above, if in Dutch. When my friend Henco had read it it he offered it to me, as he knows I like philosophical books. And perhaps because he is eternally in peril of not being able to enter his own house because piles and piles of books are in the way. I had heard of the writer, as he is (or until recently was) a columnist in the newspaper. But I didn’t know much about him.

Then I started reading. The book turned out to be a collection of columns in which Wijnberg tackles current societal and political issues using philosophy. And I thought he did a spiffing job! And I thought I’d illustrate that with a few examples. I have retold them in my own words and often added my own examples. And I know there are readers of this blog who don’t read Dutch, so who won’t be able to read this book, but maybe the examples are in themselves worth reading too.


Wijnberg starts off with the curse of choice. There is, in many ways, more choice now than ever. That should be a feast! But it is not rarely described as a curse. And I suppose we've all sometimes perceived it as such. You want a new pair of shoes, but where to start? Too many shops, too many shoes within a shop. And for bigger choices it holds too: what topic to study at what university? What person to date? It’s not one of the bigger problems of society, but it’s a small one we all know. Wijnberg explains, referring to Isaiah Berlin, who wrote "Two concepts of liberty", that if there is more to choose from, the difference between the various options becomes smaller, and there is less reason to choose one over the other. In that sense, too much choice is indeed a hindrance. Berlin also pointed out that choices are easier to make when you have a stronger identity and personality. And only one or two generations back, you were born into an identity; you were born in a social class, in a religious community, in a village or town, and you were not at all likely to leave any of these. That made the choice of where to live (where you were born), what profession to pursue (the one your parent had) and what to believe (what your parents believed) very easy. Nowadays many people grow up in a family where no specific religion is adhered to, where you don't do what your parents tell you (if they tell you at all), and it’s normal to choose your own path, and end up somewhere random. So for many of us, it holds that you will have had to make many choices before you had even figured out who and what you were... not easy!

In the Netherlands, there is almost continuous discussion on whether one should be allowed to wear religious symbols in public. Those against often rail against head scarves; they are seen as suppression of women, and as a rejection of western morals. So they should be banned. But in order to stay consistent, then also crucifixes and skullcaps and the lot should be banned. Should they? Wijnberg rightly argues that religions are artificial constructions based on tradition. Can anyone define what a religion is? Should we ban strainers, as pastafari wear them as religious headgear? You may say that pastafari take the piss, but how can you be sure? If I start a religion that reveres denim, would jeans then become religious symbols, and be banned? In other words; religions are arbitrary constructs, as Dutch philosopher Paul de Beer already argued in 2007, and you should not base laws on them. Decide as a country whether you have civilian reason to object to clothing and accessories. If you decide it’s unsafe to have your citizens walk around unrecognisable, then ban the burqa and the full face helmet with tinted glass. But leave your citizens to wear what they want otherwise.


Even though Wijnberg’s texts are all of roughly the same size, my rewordings arent’t. That care for the environment is a prisoner’s dilemma (thought up by Merril Flood and Melvin Dresher, and completed by Albert W. Tucker) is fairly evident, but it’s well-explained in this book. And this observation does not inspire much hope for effective tackling of this issue. Maybe one day environmental destruction will become the common enemy that unites us all; Douglas Hofstadter already seemed to have pointed out in 1945, but it will have to come barging into our very doors (of all of us!) before I can see that happen...

The last example I’ll give is one of which I had no idea. And you can’t come to Wijnberg’s conclusions on reasoning alone. I’ll take his word for it! It deals with democracy (or whatever passes for it) in the USA. That the power is mainly in the hands of a few very rich people (which are not rarely male, white and Christian) is blatantly obvious. Wijnberg claims that is on purpose, and anchored in the constitution; that the task of the government is to protect the minority from the majority, as explained by one of the authors, James Madison. In other words: protect the few powerful rich against the plebs. And if you look at the discrepancies of what the people want (e.g. fewer wars, stricter gun laws) and what they get (none of that) it does make sense. And the low turnout at elections fits in well: many citizens have already noticed that the government will listen to corporal interests, not public interests. And elections are X Factor shows with little attention for the policy ideas of the candidates. And some important changes for the better have been made, such as the abolition and votes for women, but it’s a long struggle.

Beside these four examples Wijnberg discusses 47 more issues, including philosophically inconsistent politicians, the difference between lying and bullshitting, animals' rights, terrorism, abortion, the strange relationship between Christianity and sexual morality, women's emancipation, disproportional salaries, human rights, the nanny state, and drugs. It would be nice if (Dutch) politicians read it too! But it's also recommended for non-politicians. Even for the well-read who find the above examples quite evident I expect a few aha-Erlebnisse!

New building crumbling

When the Marine Institute would raise a glass of mulled wine to christmas they would, of course, do that in their new building; that provided a nice opportunity to have a look inside this newest structure on campus ground. It wasn't what it should have been; the building had only been opened the month before, but already it was falling apart to such an extent that it posed a hazard for all who ventured near. The windows seemed to have been put in inside out (I didn't know window panes had an in- and outside) and the stone cladding was dropping from the walls on all sides. (For the Dutch: would it have been built by Biereco?) In order to let people safely enter the building a covered entrance path had been made. It quite took the glamour out of the entrance! It should have been the showpiece of the entire campus...


Notice the cherry-pickers and the covered back entrance


That rock put there in honour of the building and the Duke of Edinburgh looks a bit silly like this!

Size 5 shoes

When I got my new insoles my podiatrist advised me to gradually make the switch from wearing my old ones full time to wearing the new ones full time. I didn't! That would mean replacing my entire collection, and I'm terribly bad at shoe shopping. I've now used both pairs in parallel and it works fine. And by now I've managed to buy my second pair of shoes (or rather, boots) that fit them. The first pair concerned a pair of black boots - from Debenhams, where my transformation started. And the next pair I bought together with my mother. So I'm now turning into a lady with size 5!
