ScienceDaily (Aug. 24, 2006) — Cave-dating research published by Australian geologists has found that the Jenolan Caves, in central NSW, are the world’s oldest discovered open caves.

This one’s a big surprise, so first make your guess and then peek here

Sure, but they stand on terra firma. But to see a 20 foot stalactite hanging down from the ceiling, wih just a little drop of water at the tip is an awesome sight, especially when they come in a variety of subtle colors depending on the chemicals the water picked up leaching down from the surface.

I had the good fortune to visit Carlsbad Caverns, NM. some 750 down. We used the Natural Entrance route and it was awesome. Later we watched the bats swarm from the cave, by the thousands. For awhile the sky was completely blacked out.

Caves are cool and all, but what really fascinates me are the critters that live in them.  Especially the troglobites.  Those things can be freaky.

It’s stalaCtite from the Ceiling

and stalaGmite from the Ground.

That will be 50,000 years of Chinese water torture dripping from a stalactite.

Thanks for the correction, .... red face

But only people with infinite patience would attemp such torture…..I’d prefer to endure a more direct approach…..waterboarding.
