This cave remains unexplored for a reason /// CATANAMATIAS CAVE 

This video got me super excited about never going into a cave. Stoked bro.

I like the fact that the locals can still hold on the idea that the cave still holds the giant golden tree. I love the fact that this legend will not be spoiled today.

A lot of adventure shown to us in less than 8 minutes. Nice work and thanks for sharing!

There's a strange amount of hateful people in this comment section. I think they're not particularly interested in caving... Just algorithmic expatriats

That's the best bit of cave exploring footage I've ever seen. So many videos are "mistake" videos or "death" videos or "dumbass crawls headfirst into a tiny hole and ends up upside down with about a thousand people called in to rescue him" videos. Good to see one with decent size caves, repels down, climbs up, water, dry bits and new mapping. Enjoyed that one.

You folks are very brave, I can't imagine being in a small space that you aren't sure you are going to be able to get out of. Be safe, thank you for sharing your adventure.!

Should have used Toyotas

Awesome adventure! Your map and good rapport with the locals is everything!

14 second drop should be just a little more than 3,000 feet if anyone is wondering lol

Very cool. Reverse mountain climbing has always been an interest to this old spelunker. The bad air must be nitrogen and carbon dioxide from the decaying organic debris, which is seen in the video, even in the lower passages. Harmful gasses are especially concentrating in the dry sections isolated by sumps, and in the lowest, poorest breathing sections of the cave. I would be careful using a lighter as a testing device. Methane could be present, methane being a highly flammable gas also produced in the process of the decay of organic matter. I am so pleased this dangerous expedition produced no extreme drama and all returned safely to the surface, a credit to your planning. Kudos to that small Italian team as well. Were there even LED lamps and lithium batteries 30 years ago? I remember when we used acetylene miners' lamps in the late 1960's.

It's the worst feeling. Going through some really crazy stuff only to see a name scrawled on the wall, or a bolt set like yall found. Ok, not the worst feeling. It definitely leaves you with a sense of wonder at what the people who were there before you had to go through with even less technology than you had. Hoping yall have more adventures to come with yall being the first ones ever inside plenty more caves!

I can't breath watching!! How brave. Grateful for explorer spirit

Appreciate the pics and vid’s and especially your brevity. Thank you for sharing. Glad you’re all well.

I wanted to see that underground waterfall so bad

These are bucket list adventures. Thanks for sharing your journey

your tires looked over pressure for off-roading, which makes a major difference in the ride quality and doesn't shake your ride to bits.

Awesome af, you and your team, fcuk the haters. Be safe out there and keep going

Ahhh... a Jeep in it's natural form: Broken down, on the side of a trail.

Glad this has a lot of views - shocked that the channel isn't much more popular.

the level of planning and skill to pull off these adventures somewhat safely is insane. kudos to you guys for pushing the boundary of human exploration in the 21st century.

I've heard about a whole bunch of caving disasters, but if I'm being honest, leptosporosis was not on my list 😂

Great effort. I must admit the thought of being trapped underground would stop me from going caving so I admire what you all do

Very cool video. Thanks for sharing your adventure.

Yall just have fun but most importantly be safe, yall live the dream i want and live through the vids

I was only going to comment: I't might be as well, the cave system remain unexplored to the very end. That way the theory of the golden palm can live on. But reading through some of the comments I was surprised of so much negativity. Not fun to get that response. Guess there's easier being a keyboard warrior then actually doing things like this expedition.

looks like a blast, cheers for sharing your experience and making some beautiful maps!

I'm so glad to see you guys are able to do that for us to see

Muchísimas gracias por excelente video 🇩🇴🤩✨ I'm from Dominican Republic and my family lived for a long time in the nearby city of Las Matas de Farfán, never to the cave but I've been told many times about the legends and curiosities of the cave, what a great effort of yours producing an accurate map. I hope that one day, the Dominican authorities make a similar effort and produce maps and information about the caves publically available. Thanks so much and I'm glad you had a great time in my country.

Maybe that waterfall was the raging river the other team mentioned?

Hello friend thank you for sharing your cave tour ❤,you both did an amazing job 👌❤️🙋❤️. Greetings from England 🇬🇧 Simon and Beth ❤️ 😀 ❤

You guys are awesome and so brave mapping the cave, good job. Thank you for sharing, much love. xx ❤

This is so well made! Glad you guys had fun and stayed safe :D

The action adventure twins would like this!

that waterfall was probably the river the Italians couldn't pass

Excellent video!!! Well narrated and edited!!! Thank you!!!

1:39 That is precisely why you should have your own off-road vehicles, instead of trusting a rental company to actually do maintenance on their vehicles.

Brilliant video team 👏 lots of good information, well filmed and captivating. Good job 👏

Its always scary to go so deep.. So many people lose their life by exploring. Your a group of brave men and woman. Respect!

Very cool! Thanks for sharing.

I had a friend who got into diving, then into rescue diving and then into cave diving. When he wasn't diving, he decided to do the cave exploration on land and got into spelunking. Me... I will never ever understand the mentality it takes to do that. I could probably do regular diving, but never into a cave....ditto with any cave, below or above water. I just have a deep fear of dying, trapped in a dark place, pinned and unable to move, due to something like not being able to get through a small tunnel, or a rock shifted and pins ya, or in the case of cave diving...getting an air hose snagged/ripped and not being able to surface. I think I would rather be burned alive than trapped like that, or say in the rubble of a building after an earthquake, just not being able to move, and just having to lay there and endure that until I die. My friend couldn't explain to me why he found it fun, and challenging...even when he tried to tell me about all the wonderful things he saw that maybe less than 100 to even a few 100 people in the history of the world got to see, to experience. And yes, even the thrill of finally getting out and breathing fresh air and feeling the sun on one's face or seeing the moon up in the sky...he said it just makes a person feel more alive. Still... I'll pass. I find it interesting what ya all are doing, but I also think you are all a wee bit crazy to be doing it. :P

What a cool video! The RU-vid algorithm pointed me to this and I really enjoyed it! You’ve got a new subscriber! Funny, as an avid outdoorsman, this is the only sport that truly creeps me out. I’ve summited mountains, spear fished around sharks, rock climbed, mountain biked, cliff jumped, sky dived. All in various cycles of my life’s adventures and hobbies. But this? Whew…. You guys are a special breed!

You guys should have considered adding a miniature drone with your equipment to further explore areas that you found too risky to enter. Even though you may not have received much more data from it, that little bit would have been a great advantage. At least you would have had glimpses of parts that were inaccessible by the Italians.

Thank you for this video, I could never !! Fascinating video, stay safe. ❤❤

A full-blown waterfall a little further down and a huge pocket of bad air. One day somebody's going to find what everybody calls Agartha. What's a daydream without imagining an advanced people that went 16 to 18 miles down. To get away from the Savages above start a new life.

Very educational & informative content. Will surely be used by future explorers.

Incredible video. Amazing adventure. Well done. Crow✌️

holy crap, this is awesome work! I hope your channel blows up in popularity!

Exploring caves, something I would love to do, but will probably never get too deep into. Two reasons; I'm too big and to be honest, I don't think I could handle the constant dark and tight spaces not knowing what's beyond. For now I'll have to stick to show caves and the one time I did a spelunking tour at Wind Cave in the Black Hills. Kudos to those who do this.

Caving is fascinating and horrifying. This cave looks to be one of the most dangerous possible . Heights and tight squeezes are 2 things that really scare me. My uncle is an accomplished caver in the southwest , he has been places no other humans but him and his wife have seen. He even discovered a previously unknown extinct bat . I dont think id be able to do that mentally. So much can go wrong so easily and youll never be found.

Caving is incredibly fun and nothing in life is safe. But still cant bring myself to enter any caves with the possibility to flash flood, yall are brave af

This is so wonderful, Lukas! Kudos to you and your team, and thank you for sharing. :)

Very cool adventure!

One thing bothers me - you say you couldnt find the river, and perhaps it was the wrong time of year. I've seen so many videos of cavers drowned, just from a thunderstorm. What kind of research did you do before going down, and how did you know you wouldn't be trapped by a flood?

nope. I've worked in tunnels. University infrastructure climate, communications tunnels. 3x4, bringing in a pee bottle and totting in tools. supplies and food for a 6-hour workday. A full hour crawl in and out for the 8 Nope. slimy, fungus and ...nope. A whole bag full of nope. I've gone caving , but in Eastern Washington. We see dry caves. I love that 10 foot down in the summer, those caves that go deeper are soo cool. literally. any hoo, even though my own heeebi geeebis come in to play, Love this video! keep your head down!

Excellent video. Well edited and filmed. Would love to see you make more.

That was so incredible.

Seems like the biggest challenge to any caver is "bad air" 🤢 Moreover, the deeper it gets, air quality becomes worse.

Nice! Been deep a number of times in Oaxaca and Chiapas. In my sixties now so those days are behind me now. You did a good job on your presentation.

Great video. Well done

im almost 3 mins in before they head in and bro that goose has me dying. their guide is a kind soul. thank you for being you.

This is a fantastic video and im not sure why people were so negative in the comments.

Those Italians were incredibly skilled cavers to get possibly further 30 years ago then cavers with even more modern gear can today.

That was brilliant. Thank you for this. Enjoyed ti very much. You two are very brave.

That’s so wicked. I’m totally envious of this type of exploration. Quest on, brother!!

It makes you wonder how Leptospirosis got down there as there were no rats? There must be a filthy water in fall from somewhere?

That’s so awesome! I love caving videos. Just… please be careful!! And stay safe 😊

WOW!THANKSFOR SHARING!ICOULDN,TDO THAT!

Those maps make all that struggle worth it

Its crazy that down in a cave that isnt a mine has contaminated water and bad air.

Great content, hope to see more!

Good stuff

As a jeep wrangler owner I can say Honestly it's the most unreliable vehicle I've ever owned

I like how the guy checks the air with a lighter.

What an amazing and so well planned explore indeed.

Incredible video !!!

personally i am afraid of dark, deep, narrrow places like caves and may never venture inside (depends if i get a opportunity then what i will do) but thanks for people like you to show the hidden world

Thanks for taking me caving with you all! I deeply enjoyed the trip! When will you all go back and finish the trip to the very bottom?

Looks pretty darn good!

Wow! Right next door to me. I'm a caver too here in Haiti. I live in Port-a-Piment that has the longest mapped cave in Haiti, the Grotte Marie-Jeanne. I've led several cave exploration expeditions with multi-disciplinary teams from the US (University of Kentucky) see NSS newsletter January 2014 dedicated to caving in Haiti. On one of our expeditions we came across a deep vertical cave but did not have enough rope with us to make the descent. I took a couple of photos of the entrance I could send you. The cave looks really promising and no one has ever been down it. If you're interested in verticals let me know.

And most importantly: You shattered the legend of the golden palm tree at the bottom of the pit.

I had to join after watching this awesome video! please keep them coming, I'll tell others about your channel,GBU

Soooooooo.... maybe there STILL IS a palm tree of gold down there!!!

For adventure with people it may be another 30yrs but for pure exploration and mapping it may only be 5-10yrs with drones.

the cave is amazing inside

What a great video. I'm very happily a new subscriber after you showed up in my feed. Looking forward to more.

Very cool exploratiion! Thanks for sharing! Excellent mapping work! I'd love to know more about your mapping techniques. I used to be a surveyor but we never mapped any caves. cheers!

I appreciate the video and knowledge. Obviously I will never venture into such a place. So you and your friends exploring are our view of such places and I thank you for that. Just be careful and watch for dead air situations. By the way, when I was younger, I too explored caves with others...

I also hate dry passages, and unbreathable bad air.....but I'm glad you were able to continue! 😉

Good video!

That has got to be a giants intestines.

That's incredible. It's great fun as long as you all make it out. Sorry for the spelunker who was hospitalized.

Very interesting. Thank you.

There are less and less of truly interesting posts on youtube except this. I really enjoyed this radical adventure/ science presentation.

Love this! Thanks for taking me there!

Change in elevation caused wrong Mapp sensor reading to computer. Disconnect battery ground to battery for a few seconds, reconnect and try again.

intriguing...

This is pretty neat. Spelunking is deadly but SO interesting

1st mistake was driving a jeep on that road. Should've driven a toyota.

Never liked caves and amazed folks such as yourself do these things. Daring and dangerous.
