This may be a bit of a silly question but I’m trying to research this for a fanclan and I cannot make a fox’s tail out of the non twoleg workings

So how would you/Windclan go about reinforcing the tunnels? Used to think it was just ‘put a thick branch up there and every few fox lengths, it’ll support all that’ and that doesn’t seem quite right anymore. Please and thank you 🐈‍⬛

I'm gonna try and keep this reply simple and not get into the in-depth mechanics of digging holes, that's a post for some other time and I'd have to talk about depth and learn math and shit

So very simply putting it, usually, you would naturally dig square tunnels, and this is where all the tension of digging comes from. See, a square tunnel is really bad for physically holding things up, so beams are there to help.

Think about a tunnel kind of like building a bridge. The tunnel is a structure that needs to hold up the dirt above it. Really, functionally think about how many bridges are truly flat; it's not many! You want Arches.

And, it just so happens, a tunnel ALSO wants to be an arch. I'm not sure if I'm explaining this well so I drew a little diagram of a cave-in;

[ID: A drawing of a square tunnel with a dotted line showing the arch of where the dirt will collapse. It progresses into the second drawing of a rock fall, revealing the arch of the first drawing.]

Most cave-ins aren't the ENTIRE tunnel collapsing, it's the part of the tunnel that WANTS to be arch. Arches good. Arches are physically the best way for holding things up. Problem is that you can't dig like that without dropping however many pounds of earth on yourself.

So really, what you want is a beam, not just a stick in the middle of the hole. You want to put a beam from wall to wall, supported by two columns beneath. Like minecraft.

Other various things;

Older tunnels are, actually, usually more structurally sound. There's been more time for them to "stabilize."

The deeper the tunnel, the more stable. This is because the earth above the tunnel is packed in better. You do NOT want to open up a staircase downwards like minecraft, the entrance will COLLAPSE.

However, naturally, a collapse in a deeper tunnel is more deadly and severe for obvious reasons.

Just to state the obvious, sand bad. You do not want to dig in sand. Sand Bad.

Canon vastly overstates the severity of shallow tunnel collapses. Cats will die in less than a foot of dirt :/ There's this part in DOTC where Jagged Peak activates a quicktime event and a burrow collapses on him and it was so profoundly stupid it's been in my head ever since

suffocating in an old animal burrow... girl... do you think rabbits are constantly dying in collapses? genuinely? In soft soil?

Gray Wing is like, "you almost out bro?" and Jaggy-P is like, "ya im coming" and then WHOMP. DIRT. thats not how this works thats not how any of this works

And as a final note... the problems with WC's portrayals of shitty parents aside, it actually makes perfect sense that Tallpaw would think his father Sandgorse is a lunatic for feeling safe with going right back in after a collapse. Tallpaw doesn't know that some kinds of cave-ins actually make the tunnel more safe, but Sandgorse, an experienced digger, would.

(unfortunately the writers don't know this. but i do.)

Poll Redux: Tunneling

WindClan was unique for their Tunneling and Moor Runner systems back in the day. These systems ended under Heatherstar, but times sure have changed.

Am I the only one who thinks that one of the last things tallstar should have done was bring back the tunneling system when they got to the mountains? like, I think that would have made things alot more interesting and I hate how they introduced the tunneler job thing in Tallstars Revenge (and maybe other books too i dont remember) and dont mention it or bring it back

The first lines of my WIP

I have for you all the first lines of my current WIP, tentatively titled Tunneling unless I conjure something better before finishing it. This is from the prologue of the second draft, but these lines have been through more than just two passes, and I expect this to be just about the final version.

As these are the first words you would read upon opening the book, there is little need for context. All I will give for now is that this is a sci-fi/fantasy story spanning several planets (I find it difficult to pin it to any more specific of a genre). Here are the lines:

For a time, the universe paid no attention to humanity. The reverberations had fizzled into the vastness of space quick enough to make no effect. Stars flew on courses in galaxies groaning to the rhythms designed for them, and the universe was content from the conductor’s seat. Harmony dominated. It was not perfect—it never was. A missed note there. An off-key melody that wobbled some planets. Those had always been fixable, though unfortunately, the best way to stop a faulty instrument from ruining the orchestra was to destroy it. There were plenty of stars to drown the silence that followed. But never before had a broken instrument produced music once more.

My hope is that this sets the stage for the tone of the book, and for the remainder of the prologue, there is a POV character setting the spark for the rest of the story.

(Note from the final author: If you're interested by any of this, I will be posting the premise and some of the worldbuilding behind this series soon. It's planned to be 5 books (with 3 sequel books, of course, because I can't help myself). The series is called Seven Forces in my head, but I will think of a better title eventually.)

Tunneling: Methods and Applications

In the vast realm of civil engineering and infrastructure development, tunneling stands as a pivotal and fascinating aspect. It plays a crucial role in connecting people, places, and resources, allowing for efficient transportation, access to resources, and even scientific exploration. This article delves into the intriguing world of tunneling, exploring various methods, their wide-ranging…

I hate Heatherstar for destroying tunneling, and it's one thing I'm grateful Onestar brought back. It makes Windclan unique, ya'know?

I mean I wish Onestar brought it back, but modern WindClan tunneling isn't really digging like it used to be, unfortunately. It seems to have just been used that one time to attack ThunderClan.

Which is unfortunate because it's such a good and interesting skill, y'know? I really loved the glimpse of it we got in Tallstar's Revenge. The way they could hear and differentiate pawsteps underground was super cool, the idea that Tallpaw's running skills didn't translate to moving fast underground, all the discussion of digging in different types of terrain...

Really, I think my favorite thing in warriors is when the cats problem-solve, LMAO. I'll be hooked if you just put a bunch of cats together and have them figure stuff out.

Every time there's a scene where they're like, "How WILL we reinforce the nursery brambles in leafbare" I fall for it hook like and sinker like "omg dustpelt how WILL you reinforce the nursery brambles... girl the brambles won't be soft and pliable until greenleaf when there's new growth..."

#which is why the opening half of bramblestar's storm before it becomes a shipping book is the best stuff in warriors #I ship Me x Gross Blanket That Needs To Be Stretched Over A Bush to Dry #WindClan #Tunneling #The death of tunneling is so upsetting to me that it gets beefed up a lot in the rewrite as something Heatherstar smothered-- #Not just because it was dangerous #But because it prevented WindClan from battle training #I don't like how Tallstar's Revenge made Cedarstar into another evil ShadowClan villain #Like... this whole time it was all ShadowClan to blame and not a problem with the warlike culture?

A report just came out from a Palestinian hostage saying he was strapped with bombs and sent into a Hamas tunnel, with Israel prepared to blow the tunnel up with his body if fighters were found inside and yet people are still making the “Hamas uses human shields” arguments that have been confirmed to be a myth with no supporting evidence

#the hostage also said the same thing happened to a 15 year old boy hostage #both of them did survive as they were pulled out of the tunnel when no fighters were found and then released a few days later #the amount of people (including the US president) who still talk about the Hamas human shields is alarming #since no one has evidence of it and we have more then one piece of evidence of Israel using human shields #palestine #🦢

Abandoned Tori Gate found in Japanese Tunnel

Such gates are used to mark the entrance to sacred grounds or gods' territories. "The tori gate symbolizes the division between the sacred and the profane, and is considered a spiritual gateway between the physical world and the spiritual realm."
