I browse an All > New to find communities I like. There’s not really so much content that it’s overwhelming, unlike if you did that with a huge site like reddit.
How is that not what cheese is? As far as I understand, every cheese uses a bacterial culture, mesophilic or thermophilic. Blue cheese is different because it also has a fungal culture. But sure, usually it's put in on purpose when the cheese is made, not something that comes from the environment.
Yeah, the articles about this explain how there was a multi day rescue effort, several people were so traumatized they never wanted to cave again, one rescuer got smashed in the face with a pulley that came out of the ceiling, and the cave ended up being sealed with concrete. It was known as an easy cave though and the rescuers weren’t otherwise in danger.
I could see what he means, and that happens to me sometimes too. I've thought background noise is all sorts of things. it is very quiet down there (we were I think at least a mile underground, having walked roughly horizontally for 5 hours). It's still to me just a classic amusing 'oh great' thing to tell someone in that situation.
It is pretty awesome, really. Definitely adventurous. I'm sure for people brave, fit and unwise to enough to do it, that's an amazing experience. People do it under the ocean too. The problem is being hours down in a cave that can only be accessed by experts at rock climbing and scuba diving is just about the most remote location possible.
We had some interesting times on the one expedition I did. It was fascinating and I would recommend trying it at least once... doesn't have to be dangerous. Even going to Carlsbad Caverns, which is a National Park and while not the real spelunking experience, pretty cool. I went to Wolf River Cave in Tennessee. Most of it was just like mountain hiking, but with a ceiling. Questionable parts included crawling in light mud on our hands and knees for 600 feet through an area where the ceiling was about 3 feet high. Also one part, you go through a 'door' and have to drop down ~5 feet onto some rocks... people told me "be sure to go left when you land!!" and wtf was to the right? This giant dark pit of rocks at least 20 feet deep. Okay... then at the very bottom, there was this area with a bunch of trickling water and awesome stalagmites where you could sit on rocks by this weird little stream and ponds. We split up and sat in different rooms... the guy from Kentucky I sat with, who I'd never met before, told me "sometimes when I'm down here... i listen to the water... and it sounds like people talking..." Uh, okay.
But anyway it was an amazing experience and profoundly strange... the 'rooms' and 'hallways' are oddly reminiscent of human construction. And if you get stuck or hurt, if you've done things properly and signed in and people know you're there, experienced cavers will come and rescue you.
Some of the stuff describe in the spelunking journal is insane, like "okay, we'll rappel down this giant cliff, then there's a pond at the bottom, so we brought our scuba gear..." Cool to hear there's videos out there! I had never thought to look for some reason. When I went caving (around 2005), it was a 9 hour journey and my digital camera died on the 2nd photo, which sucked.
