crystal caves

Did anyone catch the special “Into the Lost Crystal Caves” on National Geographic channel over the weekend? Totally amazing… (more after the jump)

What kept tripping me out was how hot it is in the caves. I always have had this preconceived notion that it would be cold, I guess because of those Superman movies or other sci fi movies. Anyway- as I mentioned before, Totally amazing, and fascinating. If you can catch it again (supposed to repeat this Sunday), well worth watching. More info, photos, and footage on the NatGeo site.
