All photos: National GeographicBeen meaning to post this one for a looooong time--and thanks to Eiglophian Press for jogging my memory! These are absolutely amazing and REAL! National Geographic did a story in 2008 and ran a TV special on Mexico's Cueva de los Cristales (Cave of the Crystals). The cave boasts some enormous crystal structures (among the largest ever discovered). The cavern is part of the Naica mine deep under the Chihuahuan Desert. It's like something out of a Jules Verne novel, but REAL! But don't take my word for it, from National Geographic:
Hidden deep beneath the surface of the Earth is one of the greatest natural marvels on the planet: a giant crystal cave with crystals up to 36 feet long and weighing 55 tons. But this scorching cavern could kill humans after just 15 minutes of exposure.
Take a look...
Seriously, this is just about the coolest discovery I've ever heard of.
