amazing crystal cave in mexico

I have not seen a thread on this ,amazing pictures and scale reminds me of supermans house in the arctic..

"Miners working in the Naica silver mine broke through the walls of the cavern and were astounded to discover these enormous crystals - the biggest anywhere on Earth."

news.bbc.co.uk...

This was posted a while back, though I can't seem to find the thread. My google-fu is weak today.

Either way, it's incredible. The size of those crystals are HUGE, it's hard to tell until you see a person near them.

yes,
there's a thread here.
