Below the Chihuahuan Desert in southeastern New Mexico, lies an extensive system of limestone caves, among them the pristine Lechuguilla Cave and the famed Carlsbad Cavern, home to one of North America's largest underground chambers. But there’s more to this subterranean world than gigantic geological formations. It's also ground zero for a microbial war that’s been raging for thousands of years, right beneath our feet.
Untold Earth explores the seeming impossibilities behind our planet’s strangest, most unique natural wonders. From fragile, untouched ecosystems to familiar but unexplained occurrences in our own backyard, this series chases insight into natural phenomena through the voices that know them best.
Untold Earth is produced in partnership with Atlas Obscura and Nature.

I found them endlessly fascinating and beautiful. This was wonderful to watch, really brought me back to the sense of awe I had touring those amazing spaces. Thank you!

it's normally because of the environment. Some people are afraid to enjoy the sciences because they put a lot of focus in social status and are afraid of being seen as a nerd. Some have had bad experiences with science as in a snooty professor or peer who was condescending when they didn't know a fact correctly. I haven't met one person who isn't into science, just some people who aren't aware their passion contains science. Same with math...that stuff is EVERYWHERE!!

It really makes you wonder if all planets and moons in our solar system are truly devoid of all life or if there are caverns like this far below the surface(or under ice sheets). Where bacteria and simple organisms have been going at it for millions if not billions of years.
@jandrews6254
@jandrews6254 Месяц назад
Given that earth life exists inside active volcanos and in the deepest parts of the ocean where there is incredible pressure, absolutely no light, no oxygen, just black smokers, I’d say the planets and moons mostly have life just not 9’ tall blue humanoids with boobs. We need to see past our own egos and recognise alien life when we do eventually find it.

I finally visited recently, and it truly is breathtaking. It's kind of like seeing the Grand Canyon in person. You can look at a million gorgeous pictures of the place, but it doesn't do justice compared to seeing it in real life. I would easily recommend this for a bucket list visit, at the very least. Just a few tips, when visiting. Wear comfortable but supportive shoes and get ready for a serious calf workout. The trail down there is miles long and almost none of it will be level. If you have breathing conditions such as asthma, please be aware that there will be pockets where it isn't as easy to breathe. I definitely regretted not bringing my inhaler with me. PLEASE DO NOT TOUCH ANYTHING. Keep it beautiful for future generations to enjoy. Be safe and have fun!

@RobinTheBot The ranger told us to avoid touching anything aside from the handrails. This was back in February 2024.

The rangers seemed pretty serious about it, talking about preserving the biological climate down there.

My family toured the caverns when I was about hand high to my dad. I say it that way because, I got too close during the tour and he turned suddenly, accidentally striking me in the mouth. I lost a "baby" tooth in Carlsbad Caverns and as far as I know, that small part of me is now a very small part of the cavern system. Even with loosing a tooth, that visit to the caverns awed me at the time, and have ever since. I'm 67 and still remember the beauty of Carlsbad.

My dad and I visited Carlsbad Caverns back in 1976. I couldn't believe how big and open it was. It was still relatively new in that they were still making discoveries in areas that hadn't been researched or even found yet. While I had a hard childhood I was lucky in that the rare good times I did have were of incredible people, places and things. Good thing I always try to find the silverlining. ;)

If you visit Carlsbad Caverns, be sure to take the natural entrance if you are able. If you take the Visitor Center entrance instead, you'll just go down an elevator and step out into the Big Room. Kind of anti-climactic and boring. It won't be _nearly_ as impressive as going down the natural entrance, where following in the footsteps of explorer Jim White, you'll go down and down and down and down, entering chamber after chamber, each one bigger than the previous one, until you finally end up in the Big Room, so large that when White held up a lantern, he couldn't see the roof of the cavern. That's how you experience a little bit of the wonder he experienced!
