Largest Cave

I just stumbled upon this National Geographic article of a cave in Vietnam. I've never seen or heard of such an incredible cave before! Apparently it is the largest cavern in the world (not longest but biggest) at 2.5 miles long, a sustained 300' wide and 600' high. Don't miss the pictures - they're unbelievable! Many of them have people in them, but you don't always see them at first because they look like ants in the picture!

Update: National Geographic has posted a video in which the photographer narrates and gives a presentation about finding and exploring this cave.

Pictures

I've finally gotten around to posting several albums on Facebook, some of which you may actually be interested in...
One in particular I'd like to draw your attention to is the Luray Caverns album. I Cantori toured this cave while on a concert tour a few weeks back, and the place is just amazing!
Facebook album for those who prefer social networking with pictures.
Shutterfly album for viewing larger, higher quality photos (use a fullscreen slideshow for the best experience).

Hope you enjoy! and if you're ever in northern VA, I recommend visiting these caverns, they're really quite amazing!
