Dang, that looked like a LOT of fun!!! More of this!

It's caving, it's an addiction, so true!

As a caver myself this was pretty cool to watch. Always figured the forces would go up while ascending but seeing it done is super informative. Thanks!

Thanks for starting this series!! You can tell your slightly out of your knowledgeable area of ropework, but that makes it even more fun as you can tell your exited about learning it as you go.

Amazing, love this twist of HowNotTo

Can we see the full caving expedition????????

This video I learned the most from. I'm a TRT or part of a technical rescue team. 95 percent of what I do is rappeling. Absouloutlety brilliant. Thank you. By far one of my favorite channels....

Careful or you may never go back to highlining or bigwalling. Come to the dark side.

I am a canyoneer, I sometimes train with cavers since we use similar technical skills to manage our rappels. It would be awesome if we could test forces the way that canyoneers use rope and anchors. We often are carrying everything we need such as wetsuit, dry clothes, rescue equipment, extra rope, food, and water in our backpacks, I wonder what that adds to forces. We also use natural anchors such as knot chocks, dead man, rock piles and retrievable setups such as the fiddle sticks and others. I would love to see how much force is required to break a fiddle stick, or slip and fail. I can send you one if you are interested. and the bigger question is how much force do we need to stop someone while belaying... The longer the rope the harder and longer pull required to slow someone down. For example while doing the 300ft rappel at Englestead Hollow, the belayer was unable was able to slow me but not stop me. Awesome video, I am a fan of your channel. Do you know any good mom jokes? Since we also do canyons with water in them, I also noticed that one rope in particular gets a little more frictionie (not a real word), I wonder if we can prove if some ropes get more friction when wet.

This was also really cool to see because I went caving last weekend and have been wondering what forces are involved and then bam! This video comes up. Awesome work.

your channel is pure gold my friend thanks!

Awesome. My heart ❤ is racing. I'm panicking and loving this. I do feel alive just watching you guys. Love it

Great one, hope there will be more caving in the future!

Sweet zebralight! The best headlamp ever!

This is why I support the channel🤓

Dude if you ever want to come to Utah I can take you to some absolutely gorgeous alpine caves

Look forward to more caving content

Cool video Rachel!

Great video and really well explained! I’m really glad to see an engaging video with useful information about caving on KZfaq. Hoping you make more!

Pleease make more videos about this! Awesome video!

As a keen caver I found this very interesting and informative. I'll be looking forward to seing more.

Loving this, hope it becomes a series

I was a climber who started caving...watching those guys put the fear of death in me...

This is so rad!! I want to explore every cave now!

Suck video dude. Love how you are finding new ways to record content. Keep it up!

So cool! Always loved cave formations on the surface when hiking. Never had the guts to get into the subterranean world, great to get a peek at it like this!

Love this. More of this!

Thank you! I felt like I was there.

Looks like Highline 🍁 rope. Danger rope. Good stuff.

perfekt video and beautiful cave.

Awesome episode. More of that cave please !

Forces in action!

Lmao i work in a cave and its my birthday today and you posted about caving thats dope

Hey, I was here last weekend! It was definitely one of my favorite vertical trips thus far!

Never been better time to go under ground :) I'm so clueless about caving while there're so many caves around where i'm... Thanks for sharing!

Awesome!!

Nicely done!

Great video, very educational, cool to see the numbers in real life. I was wondering if you guys have thought about doing a video on UV damaged soft goods, slings, dog bones, ect. Break testing some dog bones that have been left as perma draws would be interesting. Thanks, you guys are awesome! We appreciate all your hard work!

Welcome to the party my friend

Brilliant! Was wondering this fr a while now :-)

Welcome to the Dark Side! As a caver I found your magic strain gauge fascinating. Can you do a video showing how easy it is to break through a cross-loaded locking carabiner on ascent or rappel? Many cavers (especially new cavers) don't realize that can happen just with body weight, unless they read American Caving Accidents annual, which often records deaths on rappel due to this dangerous configuration. (which can happen quite easily when passing rebelays, even to experienced people, if they've got certain combinations of carabiners, descenders, and D-ring.) Maybe you've already got this kind of video but by making it caver-focused you'll reach a whole new audience and possibly save a life or two For reference see ACA-50 (50th Anniversary edition) which records a rare instance of documented "cross-loading rollout failure" of a locking biner sleeve breaking on rappel (26 May 2015 event) (rare because the caver actually lived, so could be interviewed).

This was awesome. You need to test some caving traverse lines and deviations next time.

Siick

Very cool!

The Y-hang seems to be the Karash (aka Fusion as she says), not F8 bunny ears as illustrated with Animated Knots clip.

Great video! Would love a canyoneering video where you test at what force a clove hitch carabineer block slips at.

Great vid. Diggin' the caver love. Natural evolution to your content. We're ugly cousins in a way.....

Great content as usual! Question regarding the bolts in this video. You mentioned the rock is limestone and those are wedge bolts. The bolting bible briefly mentions using glue ins for sedentary rock, which limestone is. Curious because there is a lot of limestone near me. All I ever see is wedge bolts. Are glue ins just the preferred option for limestone? Does it depend on the localized limestone and it’s hardness? Looking forward to the new additions to the bolting bible!

"I have never done a hole this big," looks down trying not to laugh "its a pretty big hole"

Moooar!

GREAT VIDEO. Been looking forward to you doing this for a long time! So you going to breaktest some petzl BAT'inox? Originally they had 50kn shear 50kn pullout stamped on them (I still have an old one like that) then one day without changing the product apart from no longer stamping 50 -- 50 | they now certify them 25 shear 15 pullout. So when do they pullout of standard concrete, 15kn and 50kn are very different numbers

🙄 That was my first thought, when I saw you in a puffy. You'll shred it for sure.

Bro somebody take me caving!!!

2:41 ....Cool 😏

This looks sick! Anyone know of anything like this in Wisconsin?

Why was the term “jugging” treated as taboo? I understand ascending is the super proper term, but it seemed that “jugging” was met with a little negativity

I really enjoyed that. since I always love when you dive into the world of climb ethics, is there also some kind of caving ethics? like don't leave stuff behind; material of bolts; does "trad caving" exist, etc...

That knot looks like 'bunny ears' which is a double figure-8 loop. In climbing we use it to tie in to a belay station. Saves gear and untying the rope between climbers. Same knot ?

How deep was that cave. From the tree to the bottom ? Thanks..

Caves are scary.

I know it's a 1 year old video now, but still got a question, how do cavers stay on track, like (to not get lost), among all the splits in the routes? Do they draw a map? Do they leave temporary signs on the walls?

👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼

Ah what you call a super 8 we call a “rescue” or “a rescue figure 8” 🇿🇦

My inner Michael Scott really wants to say things around 2:35

So next video is highlining in a cave? ^^

Caving is something that scares the crap out of me!

Have you heard of the figure 8 knot variation that can be pulled from both end (in opposite directions) and the loop without loosing strength?

Any know what cave this was?

9:30 minutes. Super safe enough...?

I don't wear a helmet either, I find that I hit my head more with a helmet than without. I also don't bring knee pads, but I do do shin pads.

HowNOTtoCAVE when?

Tennessee?

how is that solid piece of metal giving you any measurements? (I mean how, from an engineering point of view?)

What cave is that?

I'm surprised that they're aren't more dead animals at the bottom.

caving in? you must have seen the girl scout cookies for sale last week

Hey, I know that entrance! What are you doing there? Not a choice for filming though.

One... bolt? :|

What (TAG?) cave is that.....?????

Who's the goth guy ?

I cave like a dumb. If I die a cave will be why

yeeees was looking forward to this so much! such a sweet treat :)

Natural Well

8:34 0.94 km is one hell of a long rappel!
