    This is kinda cool for folks who grew up watching" journey to the center of the earth" ( no "survival" implications):

    Pictured: The Cave of Crystals discovered 1,000ft below a Mexican desert

    Until you notice the orange-suited men clambering around, it's hard to grasp the extraordinary scale of this underground crystal forest.

    Nearly 1,000ft below the Chihuahua Desert in Mexico, this cave was discovered by two brothers drilling in the Naica lead and silver mine. It is an eerie sight.

    Up to 170 giant, luminous obelisks - the biggest is 37.4ft long and the equivalent height of six men - jut across the grotto like tangled pillars of light; and the damp rock of their walls is covered with yet more flawless clusters of blade-sharp crystal.

    They are formed from groundwater saturated in calcium sulphate which, warmed by an intrusion of magma about a mile below, began filtering through the cave system millions of years ago.

    It's an oven!

    I saw a special on Nat Geo about it. Pretty cool stuff. I couldn't help but think of "journey" myself :)

    The humidity is near 100% and the temperature every bit as high. I read somewhere that the Mexican government is trying to make this cave more comfortable so it can be opened as a tourist attraction.

    Is it me or does that first picture look photoshopped?

    Now that the cave has been dewatered, the growth of the crystals is stopped. The whole crystal growth thing is based on submergence in the undisturbed solution. But you knew that from growing rock candy in the fridge when you were a kid.

    Adding to the "weird look" is the lighting. Cavers use "painting with light" techniques to light massive rooms. The camera is set upon a tripod,in the dark room, the shutter is locked open and some body moves around theroom and fires flashes at various places in the cave, one flash pop would not be enough light for a massive room. Notice the "hotspots" through out the picture. Folks usedtuo use alot of the largest old "bulb type" flashbulbs because they were fairly rugged in the wet,put out a lotof lightand could be fired with a low voltage battery.
