I believe thats how its spelled. But i remember hearing about it on tv. It's an underground cavern that has many narrow but natural tunnels of varying size in the state of New Mexico. For the life of me i cannot recall the show i watched on tv where they showed a couple of people spelunking and eventually swimming in this sprawling cavern that is vast. I don't recall how big but they said it was many miles.

Interesting. If you remember the show, be sure to tell us. Have you tried a google search?

Also try 'ask jeeves' snor:

I don't particullarly like jeeves. It's not as easy to use as google, and besides it always gives me the same answers. Although it is better than searching through MSN.

the correct spelling is Lechuguilla. I have found a website. www.extremescience.com/LechuguillaCave.htm and another site www.mysteries-megasite.com/main/bigsearch/lech.html
