Enough to make a rock dork drool!

Have you seen the latest National Geographic Magazine? Well, they've found Superman's Lair. Those are giant gypsum crystals that they found in the Crystal Cave in Mexico. The photos are just phenomenal. They're as big as telephone poles...I was watching the documentary on it last night...super cool. Well, maybe not cool. It was like 115 degrees in there. Amazing, huh?
