The underground world of hobby tunneling

2 years ago (bloomberg.com)

If you all enjoy digging hobby tunnels, then can I interest you in someone excavating their basement using only miniature remote control construction vehicles?

> Ritchie isn’t digging with any destination in mind; he digs for the pure joy and meditation that comes with it.

> “I just feel like a kid again,” Ritchie said. “It really puts me in the moment and relieves stress.”

In a world saturated with "productivity porn" and side hustles, I just absolutely love that.

  • I’m nearing 40 and when I’m at any beach with sand you better believe I’m gonna see how deep I can dig a hole. Brings back a lot of that childhood joy of being absolutely certain I was almost about to dig through the earth’s crust once it started to get hard.

    Only about 19.999 miles short if we’re talking about averages.

    • The fact that digging a hole on the beach somehow summons children and adults both out of thin air excited about the project and offering to help is something I love oh so much.

      The best I've done was a three tier well rounded circle about 15 feet across and it took the better part of two days for an entire house party size crew to dig. In tiers because it was sunken seating around an even more sunken firepit, to keep it out of the wind and solve the smoke-in-faces problem. While sitting on the first level your shoulders would be level with the surrounding ground. Far enough back to be above the tide, and when not in use we put traffic cones around it so it would be at least a little obvious in the dark and not a death pit. Filling it in at the end of our trip was a ballache but the only proper thing to do.

    • I'm past 40, my older child is 9.

      First time I went to the beach with her, I had this sudden memory blast: we should dig a hole. It is indeed a weirdly satisfying feeling which I had forgotten.

  • “Get a hobby: work with rocks and cement like John Dunsworth”[0] - you can tell that this actor really dug it!

    • John Dunsworth was such a gem. Arguably the best portrayal of alcoholism on-screen ever. One of the kindest people ever, according to absolutely everyone. Brilliant actor, and an excellent stonemason privately. He explicitly wanted his hobbies to outlive him.

      For those who don't know, John played Jim Lahey in the surprisingly excellent series "Trailer Park Boys". Give it a watch, you may be surprised.

I have a crawlspace under half my house, and made the mistake of watching a YouTube video about how to do "underpinning". Now I want to dig it out down to 10ft to use for some desperately needed storage space, maybe some gym space. Our local building office is amazingly supportive of DIYers, and I appreciate them double checking my work.

  • You don’t need to dig it out to get more storage space: https://www.youtube.com/watch?v=-k3mVnRlQLU

    • At the time that video came out, I highly considered something like that, but honestly I'm already using that space, I just need more of it. :-)

    • Unless I'm mistaken, we both read the same physical copy of Cliff's book back in '99. Talk about a small world, running across this comment was wild.

  • Oh man, don't send me down this rabbit hole! I've always been annoyed at the original builders of my house for the half basement/half crawlspace - I mean, how much could it have possibly added to the cost of construction to just dig that last 4 feet on the other half?!

    • My Grandfather’s house was like that when he bought it. It was built on a hill that sloped down from the street. The ground floor was actually several feet below the level of the street, with just enough crawl space at the front edge of the house. He jacked the whole house up to street level, dug out the basement, poured a concrete slab under the whole house, built concrete block walls around the whole thing, and built a staircase up to the main hall on the ground floor. Half of the new floor became a basement workshop, and the other half became four bedrooms and a bathroom for the children (there were only three bedrooms upstairs). Even then six of the children were still sharing a room.

  • I did that in a low basement once. I had to replace the crumbled concrete floor anyway, so I figured I’d dig it down a foot or two while I was at it… then I found out the house was sitting on a shale ledge.

    Turns out excavating shale by hand or with a jack hammer is incredibly difficult! It breaks into tiny pieces, bit by bit. Then you have to shovel said pieces into buckets and haul them out. Really heavy buckets because rocks.

    One of the few jobs I threw in the towel and hired out. It still took 3 people 2 days to dig out about 18 inches. Never again!

Youtuber Colin Furze is in the midst of some underground shenanigans and I really love watching him.

  • I do recommend his videos. He's got a very strong personality that may be to the disliking of some (including myself initially) but the more I watch the more I think it's genuine and have even come to enjoy it. But his work ethic and "just do it" attitude are really inspiring in a way. I was glad to see him called out in the article.

    • I love that he doesn't force content. It's ready when it's ready. He does have a newish channel "2 Much ColinFurze" which I like. It's less polished content, but I enjoy it.

Philosopher Susan Wolf talks about the "meaningful life" as, "lives of active engagement in projects of worth." A classic example that is given about how important both are is the idea that while one can actively engage in digging a hole in their backyard, it won't lead to a "meaningful life" because it's not a "project of worth."

This hobby I suppose could serve either as a strong counterpoint, or would reveal a whole bunch of empty souls. Up to you to decide which.

  • Is it ironic to pick up a hobby of digging a hole to fill that hole in your soul? For some of these people, it could be "meaningful" enough - after all, meaning and value are subjective. Or, perhaps the very meaninglessness has value for them, like a game without a practical purpose.

  • The nihilistic view is that nothing matters anyways. The sun will die. It doesn’t matter if you are Bill Gates. In 1,000 years, most traces of our existence would have been forgotten. Look at the ancient kingdoms and rulers. Sure, the pharaohs we care about, but some random king elsewhere? Maybe not.

    • That's the nihilistic future. The optimistic future sees the human raise up further and further and beyond the solar system. Not as humans anymore, but evolved. There is no limit.

this is the final frontier. we've conquered the land, the oceans, the skies. some people live in orbit, men have walked on the moon.

but you can still carve out a new world for yourself. you can still go down. there's enough room down there for a whole new world, with different borders and nations. and another one below that .. layers and layers like an onion. one hundred billion mole-men, saturating the earth's crust --

  • thought your comment was going to become a quote from the Artilleryman from Jeff Waynes musical version of War of the Worlds!

    "We're gonna build a whole new world for ourselves. Look, they clap eyes on us and we're dead, right? So we gotta make a new life where they'll never find us. You know where? Underground. You should see it down there – hundreds of miles of drains – sweet and clean now after the rain, dark, quiet, safe. We can build houses and everything, start again from scratch. And what's so bad about living underground, eh? It's not been so great living up here, if you want my opinion."

  • Futurama's (old) New York. But that's the domain of the sewer mutants. They flush their unwanted reptilian pets to the sub-sewer, where they become monsters.

This is awesome Sandland got some mainstream news. I look at them as a hackerspace with professional members, and sometimes mining engineers. Not mentioned is City Museum in St Louis. They let little kids roam the tunnels!

Colin Furze gets a mention in the article. If you enjoy this kind of content his recent videos (and his “too much Colin Furze” extra channel) are good fun.

I love the story of William "Burro" Schmidt.

He was a miner in California. He had a reason, somewhat flimsy, to dig a half-mile tunnel through a mountain. Nominally it was to connect his mining claims to a smelter.

He started digging the tunnel, by hand, on his own, with pick-axe and dynamite. And, once started, he kept going, straight through granite, for thirty-eight years!

Finally he succeeded. He got to the other side.

It must have been a disorienting feeling -- "I've been digging for thirty-eight years, and I've achieved my goal. What do I do now?"

You'd think that maybe he'd finally start to set up his mine and run cars full of ore through the tunnel. That was the point, right? The whole justification for the project?

Nope. He sold his claim and walked away.

https://en.m.wikipedia.org/wiki/Burro_Schmidt_Tunnel

It's the most wonderful, absurd, existentialist story, and it's real.

I forget where I first read it. This telling looks like it captures the right feeling:

There’s an old myth that Seymour Cray used to dig tunnels in his backyard.

A friend of mine said in Moscow Russia people use to dig basements under precast concrete car size storage units. Every once in a while the the whole unit would fall in the hole halfway or more.

This article reminds me of 3 Alarm Lamp Scooter:

Such a sad yet interesting story.

I wonder if there's DNA markers that predispose people to this type of "hobby". There's evidence that humans lived in caves and underground bunkers for extended periods of time. There's even ancient underground cities with dedicated water sources and ventilation systems.

See: https://en.wikipedia.org/wiki/Derinkuyu_underground_city

  • There is certainly some psychological component at play. One of my favorite childhood memories is of me and my cousin digging tunnels for our hotwheels cars in a 10' mound of dirt my grandpa had hauled in. I recently tried this new Enshrouded game with another friend and we dug a tunnel for our base (for no reason). I just find it... cozy?

    I think ancestral cave dwelling may for sure be a factor here, wrt evolutionary psychology (a scientific domain I wish was not as primitive)

  • Great notion! Are there any projects or publications attemtping to map preferences like 'invigorated by mountainous forests', 'enjoys building and living in underground tunnels', etc to DNA markers? It seems plausible that these preferences could be genetically embedded based on ancestors' living conditions.

Here's a really interesting one.

Tradie somewhere in QLD, I am guessing. Perhaps underneath a condo or small hotel.

At some point, they become a bit 'psytrance music video', from what I remember.

  • Judging by later videos his tunnel collapsed (no casualties) and he moved to some other outdoor location and activities.

    I can’t imagine this being safe at all in a city, with the amount of underground infrastructure and weight of buildings, houses, sidewalks and pavement all around you. Seems irresponsible.

    • Oh absolutely.

      I'm surprised that no-one located (somehow) and reported him before then.

      I'm sure the digger would say that it's just rubble (nothing structural) he was touching, but there are of course plenty of issues & it's besides the point / could be incorrect anyway.

Honest question: aren't people afraid of cave ins?

  • Yes. The people who do this and actually get far are painfully aware of the risks of cave ins. You can do a whole lot to protect yourself but it is always a danger that's looming.

Famous tunneler: Seymour Cray ( https://shop.minimuseum.com/blogs/specimens/cray-supercomput... )

In his spare time, Cray dug a massive tunnel under his house, complete with a periscope, and joked that elves in the tunnel would help him solve whatever computer problem he was faced with. As Cray himself once said: "I'm up in the Wisconsin woods, and there are elves in the woods. So when they see me leave, they come into my office and solve all the problems I'm having. Then I go back up and work some more."

A classic and tech relevant example - https://content.time.com/time/subscriber/article/0,33009,967...

> Technology: Just Dig While You Work - Monday, Mar. 28, 1988

> Where does the world's foremost designer of high-speed computers get his inspiration? Apparently deep in a dirt tunnel beneath his Wisconsin home, according to John Rollwagen, the chairman of Cray Research. As Rollwagen tells it, Seymour Cray, the company's elusive founder, has been dividing his time between building the next generation of supercomputers and digging an underground tunnel that starts below his Chippewa Falls house and heads toward the nearby woods. "He's been working at it for some time now," says Rollwagen, who reports that the tunnel is 8 ft. high, 4 ft. wide and lined with 4-by-4 cedar boards. When a tree fell through the top of the tunnel several years ago, Cray used the opening to install a periscope-equipped lookout.

> For Cray, the excavation project is more than a simple diversion. "I work when I'm at home," he recently told a visiting scientist. "I work for three hours, and then I get stumped, and I'm not making progress. So I quit, and I go and work in the tunnel. It takes me an hour or so to dig four inches and put in the 4-by-4s. Now, as you can see, I'm up in the Wisconsin woods, and there are elves in the woods. So when they see me leave, they come into my office and solve all the problems I'm having. Then I go back up and work some more."

> Rollwagen knows that Cray is only half kidding and that some of the designer's greatest inspirations come when he is digging. Says the chairman: "The real work happens when Seymour is in the tunnel."

I remember when I was a kid, there was an empty plot of land next to my Grandma's house. My cousins and I took a shovel to it for a couple of days over the summer and dug out a decent sized hole (well, for kids, at least). There really is something just therapeutic about it.

> TikTok’s “Tunnel Girl” has focused fresh attention on the amateur excavators who build their own underground infrastructure — often in defiance of local laws.

Gotta love we’re at the point where digging a tunnel on your own land, which you own, is illegal lol

  • Except she’s digging it in 200sqft of urban housing backyard in Herndon, VA USA. If you have 10 acres and want to dig a hole, go for it. But if you want to dig a tunnel in your backyard and your two neighbors houses are 100ft or less away… yeah, I would think twice.

    • Even if you're in the middle of nowhere, people expect to be rescued if something goes wrong... sort of like that Titan submersible. In the abstract it's fine to take huge risks, but it sucks when people implicitly turn those costs over when something goes wrong.

  • You need permits to dig a tunnel in Herndon (VA), so it’s not illegal. Similar to any major construction on your home. She didn’t secure them beforehand.

  • If it is in a suburban area (as is the case with the creator mentioned in your quote) a collapse would put surrounding properties at risk

    • Not just that but part of why planning exists in the first place is so they can verify things like that there aren't buried unmarked sewer lines or gas mains back there.

    • Right, in a sense, we all own the infra they're endangering.

      Now out on the farm, maybe do what you want.

    • Yes, I'd totally hate my house collapsing over me and my family because the neighboor excavated the rocks that were keeping my house's foundations stable in place.

      I assume heavily changing the water infiltration/leaking paths could also have significant effects on how the ground behaves even outside of the area that is worked on.

      PS: My dumb brain 30min after waking up: "surrounding properties" + "value" + "at risk" was the phrase I first read from your comment.

  • A badly-dug tunnel can be a huge risk to your neighbors' properties, as well as to any underground infrastructure in the area.

  • > “At the point”

    There are many things you cannot do on your property, and that has been true for a long long time.

  • Modifications to structures and land in almost all developed economies is subject to planning law. Even something as apparently free as rainfall collection can be subject to regulation. It can be encouraged or discouraged, depending.

  • Digging can affect utilities, water drainage, cause subsidence… of course it’s illegal, unless you get a permit. If you want to dig without a permit go to some place in the middle of nowhere.

  • it's for a good reason; many people who tunnel don't know how to make tunnels safe, and there's lots of collateral damage when they fail.

  • wait until you find out what happened when the temple of damanhur was discovered

OMG, that's - literally - a big rabbit hole to dig into. I started with the linked video of "ColinFurze" earlier today and I'm still fascinated and watching...

Before clicking into the actual article, I wondered (just from the title alone) if bloomberg suddenly started to cover shadowsocks or something.... lol

This American Life has an episode about a guy in Canada that did this for similarly vague reasons.

Darwin Awards material. I was thinking yeah give your house (most of your wealth for most people) subsidence yay! But in the article they point out yeah you can get poisoned or drown. Great.

Most of the worlds miners are artisanal, millions still do this for a living present day.

Often you can pay a nominal amount to go down into their (illegal) mine. I did get stuck because my western legs were to long to climb out the 10m shaft, I'd go to step into the leghold dug in the red earth but my knee would hit the side.

The reporter who shut down Kala is a pretty awful person (from their past work). Everyone following knew Kala wasn't going to have the paperwork. The reporter enjoyed going about it in a nasty way, which is sad, but that's a lot of todays media.

There are other tunneling TikToks out there.
