The Naica Proyecto studies the Cueva de los Cristales near the small mining town in the northern Mexican state of Chichuahua.

"A forest of crystals, the biggest ones on the Planet. An unreal world, beyond imagination, beyond dream.

A cave with a temperature of 50 °C and 100% humidity; an infernal place, where man, without protection, can survive just a few minutes.

A wonder of nature..."
