There's a reason no one has ever entered this cave. Not even once. 

Great protein hit

Saying "the amount of spiders in here is significant" is sort of like arriving in Hell and saying "the heat down here is significant" lol 😂

This is insane. You legit created an entrance to a hidden cave with a boulder, then crawled into it despite it being a spider den.

I recommend this experience to anyone with both claustrophobia and arachnophobia

Give this man an award. He makes entrances into unknown caves that are spider infested and decides to do it for fun and content. What an absolute unit.

I really can't overstate how much this entire video had me saying "nope, nope NOPE!". It's like watching someone checking off a laundry list of intense common phobias. "Unlnown passage into dark places?" Check, "extremely narrow and claustrophobic spaces?" Also check, "But can it also be filled with spiders? Oh and make sure the spiders fall on top of you? " check! Madmen.

I keep praying you guys make it to old age. You are rare and valuable underworld pioneers. Not many men would squeeze themselves into spider infested crevices just to peer into the unknown. I hope you guys discover something huge one day.

Most scary thing to me is imagine you are walking through the woods, no other plans just a nice walk , and you end up slipping through a cave hole entrance.

Small spaces and spiders climbing on my face and into my shirt?! That’s what my nightmares look like!! Kudos to you two. Keep up the good work and amazing content.

im grateful that you're doing this. no way i would ever keep my cool in a place thats raining spiders

Well, just when I think I've seen the worst you guys can show, along comes the claustrophobic horrors with a liberal dose of spiders raining down by the hundreds. No. Just no. But God bless you guys for living it!

The spriders thought it was safe down there and suddenly an enormous worm in red shirt show up

When I myself consider activities to enjoy in my free time, I must say that backing into a previously unknown spider infested slit in the earth, to have slightly better odds at not becoming stuck is at least 5 activities below parachuting with a pillow case. That said, it's like I can't look away from these videos. Even knowing there must be a favorable outcome I find myself holding my breath to the point of light headed-ness. Sending prayers the caving gods will be with you always. Not my cup a tea, but every one of those days invested with your son will be forever cherished by the both of you. Cheers!

Those spiders (opiliones) raining down on your head and face is the most horrific thing I've ever witnessed. This one will guaranteed stick with me in my future nightmares.

Harvestmen are a gregarious bunch and form these dense, dark bunches that look almost furry from all their long legs. They can pack themselves into a surprisingly small volume which makes it even more dramatic when they are disturbed and they begin to scatter and flee, it's just a shame how fragile they are- they drop legs so easily when pinched or dragged and I feel terrible when I clumsily damage them like this. That cave has likely been a popular overwintering spot for myriad animals including all the Opiliones for the entire time it has been open to the surface (and it may have been blocked off for some periods by movement of soil or debris), the temperature is likely quite stable if somewhat cool in the lower portions year-round.

You two are something amazing. Not many people would willingly shove themselves into tiny caves filled with thousands of spiders. You are one of the people that would though. Props

Man I’m a plumber and I have to crawl under houses sometimes but I can dig it out or worst case I could cut through the floor ( on a remodel lol) but this is next level. It made me uncomfortable to watch, I don’t think I could calm myself enough to do it. Props to you both

you prove that the human body and mind are just the most incredible things ever. the body because you are able to control and contort yourself to fit and the mind for being able to stay calm and not having a panic attack. another great and very informative video, I'd love to go down a cave one day but i have negative experience and i would just end up injuring myself and more than likely others.

4:50 Calvin: “Jacob’s out there freezing.” Jacob out there: “BRBLRGBblblbl!” 🤣🤣 This is literally why I watch you guys. Yeah the caving is neat and all, but you two are fun to watch no matter what you’re up to. Also 7:50, I did not know that! That’s super interesting. How would you describe the smell?

I’ve just found ur guys pages and have been watching new videos every day . Your amazing ! Stay safe 🫶🏼 thanks for the videos !

Happy, found you guys. Great chemistry and atmosphere. You are brave man raising a brave son. Huge respect.

*Yes we are aware that harvestment are harvestmen. *No, we cannot wear different clothes. *Yes, it is generally recommended to leave the critters in caves alone. *No, it is not generally recommended to dig open your own caves. This can be both dangerous to you and harmful to the environment. *The music is slightly self made. It's music I like, turned backwards and slowed down. *Shout out to Brantly, Waylin, Jackson and Lakai. I'm sure I spelled your names wrong, but thanks for supporting just the same.

I stumbled upon your channel recently, and I am hooked. Like most of the other people commenting here, I feel tremendous anxiety and fear, but your narration helps me to feel calmer. So many times I find myself thinking things won't end well, but then I remember you must have survived if the video was uploaded. :) I truly admire you and what you are teaching Jacob. The world needs more men like you.

It's crazy to me how few subscribers you guys have. All these videos are one of a kind, top tier quality. I've seen crappy, half assed stuff with millions of views, I don't understand how every one of these videos doesn't have a couple million each at least. Well, thanks for the education and great entertainment. Stay safe guys.

Educating people on ophiliones!! Awesome stuff guys! Been binging your content all week!

There is something beautiful about watching and feeling anxiety throughout your videos thank you for bringing us on your adventures man, it's weird I can't explain this but early I felt at rock bottom and the last hour of watching your channel has really soothed me. Really thanks for what you do!

At first when I began to watch your videos I was all tensed up when watching you crawl the narrowest passages. But....after a while, after hearing you talk about how you approach this, I understood that even though it looks bad, and for all intents and purposes is bad. There's a method behind your madness, and a very specific mindset. Which in turn made watching you a little less nervewracking, and let me empathize with the calm you must have when doing stuff like this. It's both fascinating and interesting to watch. Subscribed!

your videos are awesome. slowly over coming my fear of tight spaces because of you two!

You have the scariest and most adventurous channel and you make it all so fun and thought provoking, I love listening to your thoughts when you are squeezed down there, what a unique man you are!

You two are so hardcore, I think my head would explode if I ever tried that . Keep it up and stay safe

Great video, fellas! Anxiety inducing, crazy, good quality, informative, respectful and got my heebie jeebies going with all those spiders….great job, once again!

Dude you are absolutely amazing, I just came from watching caving and scuba diving accidents. Please be so careful 🙏 I love watching your videos and you are so passionate about something that most of us are terrified of!!!!!

Watching your videos is therapeutic. It makes some of my life circumstances seem not so bad because I could not imagine being in these circumstances... geeez

You guys are amazing! When I first discovered your channel(s) I literally got nightmares from tight caves. But now this video I'm at a point where, if I had to choose between tight spots and an endless amount of harvestmen crawling over me, I would choose the tight spots anytime! At least as long as there is nothing crawling over me...

The patience and self-control are amazing. would you say the skills learned in caving help you guys in other parts of life?

These are amazingly entertaining videos, I can’t help but notice how perfectly human sized these canals are you keep finding. Almost like you were meant to stumble upon them and explore.

entering a cave, knowing no human being has been there ever before must be such a amazing and adventorous feeling.

I once had a recommendation for Cave exploration videos, and now I'm hooked!

You guys are like astronauts to the earths depths!

Glad i discovered this channel ! You blokes are tremendous 👍🏽 😁

Dude. You got a sub and like out of me, as a man that has worked in mud holes and crawled under houses, you are definitely reliable and relentless. Those are some of the best traits to have as a genuine person.

OMG I have arachnophobia so bad & there's no way I would ever be able to endure what you put yourself thru. Glad you made it safe! Hello from Mississippi!

My anxiety is going through the roof and I’m not even in the cave! You got me checking my room now! Thanks for the content. 🙏

I love and hate your videos at the same time, sometimes i have to sit and just breath as i watch it lol. It is good to see this because i'd never go in myself.

"I don't know what I want to do with my life" best words ever said. Godspeed man. After I lost my dog to cancer I said the same thing.

you are a madman, Calvin. Thanks for the upload

I nearly threw up when I first watched your hell hole cover. Now I enjoy watching these and have subscribed.. Thank you both for helping me expand my comfort zone! Actually looks kinda fun...

Man that's just crazy especially since no one else has been in there! I would not want to go in a passage that tight. I would not want to get stuck and you don't know how stable the place is. I pray you will be safe! And also you really should have an O2 meter.

Its risky way of Life but you doing what you Love full respect. Greetings from Poland

2:30 reminds me of Minecraft Beta 1.6 terrain generation. Caves would generate, and the world would form on top of them

respect brother, thanks for sharing

6:57, is the calmest way of saying, DON'T PANIC! I ever heard, and will be stealing for the future.

The humor is what makes it fun. Keep on caving guys

Whoa, this is insane, and awesome! Enjoyed as always! Claustrophobia isn't enough, gotta throw in arachnophobia as well!😜

I think we invented houses to eliminate the need to go into caves.

This is all my fears rolled into one right there! You guys are my hero’s:)

Really can barely believe my eyes. I wish you guys safe returns forever.

They are harmless spiders. Not deadly. Just trying to find a safe place... And now they're terrified because the only safe place they knew suddenly becomes a scary and deadly place... Bless them and their families.

man my claustrophobia is kickin just watching you, i dont know how u have the guts to this but youre beyond strong

You two are absolute legends. I could never ever do that. Cheers.

Just got into watching these kind of videos after watching the guy who passed away in the nutty putty cave,I admire your guys thirst for adventure and is an experience for me to watch this 🙂Amazing

They group up like this because they're trying to keep warm! I love these arachnids. They're so docile.

Bro your a great personality keep the good work up

i love those direct experiences and the sound design is great

I can’t be the only one who thinks this, “if I was caving like this dude, I would carry a 38 with some hallow points JUST in case I get stuck like ole dude in that nutty putty cave, I would just blow my brains out… imagine no way out just stuck all constrained barely able to breath, no one can help you! So much anxiety to even watch lol but the videos do help with giving me nightmares.

stuck in a cramped space with spiders raining down on you and you're calm enough for an exposition

This is one of those videos i find really interesting to just listen to xD that's enough for me, glimpsing once or twice and then juuust listening xD

At 10:53 it literally looks as though you're crawling out of the mouth of a demonic face, what you've done there is unintentionally opened the entrance to hell the spiders are just the welcoming party. But with 99% of my free time away from work being on the internet for the last 14 years there's almost nothing that gives me genuine anxiety in video form but God damn these videos put me on edge.

I hate tight space but when u explained and talk to the camera, I feel like u r guiding and comforting me. Thankyou

I am having a panic attack just watching you scurry around in this cave 😱 so glad I am comfortably watching you from my warm bed! Cheers

You are a legend to deal with spiders in such a tight space. Respect

I've never had the creppy crawly shivering chills sensation more in a single watch of a video than I have with this one..... *shuddering noises*

You have the inner strength that 99.999% of people do not have to do these type of cave exploring. I just can't comprehend how it would feel to be so tight in small areas 100s of feet under the earth. Thanks for showing us into your world. I still get a certain feeling watching these videos & cant explain it but it's a fear for sure. 😰🤘

So I'm not scared of spiders. Not much fear of them at all except the healthy fear of the poisonous ones, but watching those , THOUSANDS! of them crawling all over you was intense to say the least. Once again a great video making my palms sweat and my heart race. Keep it coming we can't get enough of these.

People always say they would never go caving because its too dangerous and scary, but i feel like thats the part that always takes me back to the deep. The exploration, and the thrill of a new adventure is the best part.

I always love the little animations, just kinda moving the person around, like coloring outside thenlikes

I wonder how making your own entrance will ultimately effect the overall cave structure and integrity. Just curious. Maybe one day these caves could be larger and more exposed due to just the small act of forming an entrance. Edit: the spider cave scene made me actually scream in panic for you lmao

Wow this is insanely impressive.. You found a new cave never discovered from looking at the ground and knowing where to dig. Then went in, unknown, into a tiny passage 😱 It was terrifying watching you go down.. Thinking OMG how are you going to get back up! What if there's a sudden drop and you're going backwards.. Very cool. Very scary!

Yeah. This seems like a reasonable thing to put yourself willingly through You earned this subscription

Just watching this literally made me anxious lol. NOW THAT’S CONTENT

Jacob is such a good kid. Understated, humble, hard worker and respectful of the things around him. What a fine man he will be in his life.

I've just learned something about myself today. I have extreme arachnophobia, literally everyone I know jokes about how scared of spiders I am, more than what is normal. Yet those opiliones do not bother me in the slightest. Weird.

Man you guys are a unique breed of humans. It’s so wild you do this stuff for fun. I consider my self a pretty brave dude but just watching these caving videos gives me anxiety! Then throw in the spiders… no way!!

You just had the perfect storm of nightmares. Spiders in a hole I cant get out of. lol

Do you sell timeshares ?

I love you guys, I really do. I've been into caves with my son here in Idaho and we have so much fun. I'm originally from Oregon and haven't explored many caves in Oregon yet though. I've been to the lava tubes outside of Bend and done some stuff at Spencer's butte. I love the feeling, I love the videos you guys make. I love the messages you give. It just makes me smile. I could say more but I'll leave it at that. Thanks for sharing what you do, thanks for being amazing!

Fascinating when you’re the first human to explore a passage. And 8:37...holy crap, the ceiling is alive with harvestmen!

Insane. Crazy. Mental. Every video makes me want to go caving even more.

No amount of creative horror story writing could ever compete with what this man does just for fun.

hey guys i have a question. is a full crawl cave more rewarding as an experience or is it better if it opens up to a gallery? thank you so much for filming the depths of the earth for us folk too scared to venture in ourselves!

imagine youre in such a cave and someone tryiing to open it above

These all look like harvestman, generally harmless, but super creepy crawly. They eat tiny bugs that eat rotten moss and junk, so caves are perfect for them. They're also a bit closer to crustaceans than spiders ended up, so like that bit of moisture in the air

I started to "feel" spiders crawling across my neck as the video went on! CREEPY! CRAWLY! Thanks for the upload. Cave on!

Holy crap, when I finally understood when you lay there in that tunnel what it was falling all over you I seriously shat myself(thought it was small rocks or something).. sorry for that but that was one terrifying image right there. Thanks for doing it though, inspiring in a scary way.

possibly one of the craziest things i've ever seen. Well done.

bro just casually crawled into deepnest from hollow knight

Love this channel and subscribed! I’ve got a deep fascination with caves and the overall geology of our Earth’s crust. I find your philosophy on fear and conquering it very interesting and it caused me to be interested in human psychology. Do you think that exploring those tight caves could actually help someone with claustrophobia… I guess you might call it “exposure therapy”…..expose yourself to what you fear until you train your brain to realize that it’s no longer as scary as you thought it was? Yes you might have a wave of panic but you learn to ride the wave and let it come and go until your fight or flight symptoms lessen? Sorry if that’s a strange question…..what y’all are doing is very inspiring especially the fact that you have fun doing something that would otherwise be horrifying to many ! 😅

Never seen anyone break their way into a cave before, that’s awesome !

For this man no cave is too deep, no crevice too tight

You guys make this look so easy wild so wild
