Unbelievably huge and beautiful!

Wow. That's stunning.

incredible!

Yes sir.

Great, now I'm hungry.

mmmmmmm... I'm thinking Arby's now thanks.

nice name and quote change

Cool pics, Rick.

Adrian you know if I were a worldly traveler in my 20s or 30s with your bank account I would have put these caves on my top five places to visit list.

But I'm not, so it's back to work for me tomorrow.

Rick, start up your plane, we'll head an expedition into the unknown!

....better take a few token explorers with us though....the hostile natives ALWAYS kill a few people before any treasure is found.

Like the odd, never-before-seen guy in a Star Trek Expedition, I volunteer.

You mean the guy who doesn't live long and prosper?

That's a nice red shirt you've got there, Mark!

Red Shirt? What ever happened to 'expendable crew member'?

Nice link Rick. That was one of the better issues of NG last year.

You could always head on over to the Carlsberg caverns. Not quite as exotic a location, but still a very impressive set of caverns.

Fred do you mean Carlsbad Caverns in New Mexico? I've been there a couple of times and the whole time I was down there, in the back of my mind I kept thinking "These damn lights had better not go out!"

I couldn't help it.

There are newly discoverted caverns about 50 mi SE of Tucson that were opened only within the last decade. They were discovered in the mid-80's.

They're called Karchner Caverns, I believe.

Carlsbad is cool, especially the clouds of bats leaving at sunset.

A Teuton, still!

The entrepreneur in me says to bring small flashlights and sell them at a big markup.

I think the Fed Park Serv might frown on that sort of spunky ambition.

A spunky spelunker?

Hmm, must have had my mind on some of those cavernous beer halls in Munich.

Yes, the Carlsbad caverns. Lights out would be very creepy as underground caverns are somewhat anechoic.

The guides turned the lights out in a cave I went in down in Venezuela to show us what pitch black really is. Kinda creepy esp with the bats, birds(Guacharo birds that use echo location), muddy floor littered with dead animal carcasses, centipedes, rats, dank smell ect. We were about a mile into the cave when they turned the lights off.

I remember going to Carlsbad Caverns when I was a kid. Two things I remember vividly about it. One, the incredibly oppressive smell of bat shit. Yeah, you think you'll eventually get used to it? No. Breathing through your mouth just makes you taste it. And, two, my whopping disillusionment as we spent the entire tour being careful not to disturb and touch any of the rock formations, as the oils from one's hands discolor everything, in an effort to preserve this wonderfully natural wonder of the earth. . .and what did we find at the end of the tour? A bleeping cafeteria in the basement. WTF?

Watched the World's Biggest Cave on NG HD over the weekend.

Not the most exciting program, but fascinating nonetheless. That last wall is huge. And it was very interesting to learn how the cave was likely formed.

Beautiful! I'd love to visit Vietnam some day.
