Crystal Cave of the Giants
http://www.canyonsworldwide.com/crys...ainframe3.html
These are images supposedly taken from inside a cave in Chihuahua, Mexico. These were posted on another board I frequent, and some question has come up as to their veracity. Anyone want to take this one?

There is an official link here. The link does mention that without protective gear it is only possible to remain in the caves for 8 minutes. All the photos I saw on that page had people in special gear. I'm guessing then that if the OP photos are legit then they weren't there for very long.

I thought they might be one of the caves that was featured in the BBC Planet Earth series, but that was the Lechuguilla Cave in New Mexico. But judging from how incredible looking the one they filmed was, I can't see anything unbelievable about this one.
You can see a clip of Lechuguilla Cave from Planet Earth here under the "Geology" heading. This isn't the cave in the photos above though.

My brain is telling me that I used to know all about these...
I think (IIRC) that these are Megmatites (massive crystals) They are pretty rare, One of My lecturers discovered some in Norway that included an 18 meter (thats 60 foot) long plagioclase feldspar crystal! Now that is well bling. Bugger, I have just googles and I don't recall correctly! What the hell are the massive crystals called??!!! Elp!

Crystal cave
This is the crystal cave of giants found in the Naica Mine, Chihuahua, Mexico. These are Selenite crystals (gypsum) and are the largest crystals ever discovered. They are 1000 feet down in a limestone host rock where they are mining for lead, zinc and silver.
These crystals were formed by hydrothermal fluids emanating from the magma chambers below. The miners had to drill through the Naica fault, which they were worried would flood the mine, and this is what they discovered.

Cactus Wren, I was thinking the same thing...
That's absolutely gorgeous. Something I'd love to see for myself.

It's was hard for me to believe that this is real. That is the most spectacular scene I can think of. At first I thought these were PhotoShop jobs using shots of small crystal structures and inserting guys. It looks like there might be multiple light sources in the scenes.
I found these: Giant Crystal Project - Naica Mine Naica - Cueva de los Cristales

There's a tourist attraction called Crystal Cave on one of the Lake Erie Islands. When I toured it, they said it was the world's largest geode. I don't recall it having such large spikes as the one in the OP, but the crystals were of similar appearance -- and quite real. It was beautiful.

Why does it look like that?? Big fat crystals! Crystals that act like soft boxes! You could probably light that entire cave with a modest flash gun! Super stuff! etc.. In fact, someone faking the picture would probably miss the light balance that has been shown here... I for one would love to try and do a photoshoot in those caves.. the lighting would be the unique!

A rare glimpse in the cave of crystals
Mexico's Cave of Crystals stunned geologists when it was first discovered in 2000. The underground chamber contains some of the largest natural crystals ever found - some of the selenite structures have grown to more than 10m long. Professor Iain Stewart got a rare glimpse of the subterranean spectacle while filming for the new BBC series How the Earth Made Us.
