Buried a thousand feet (300 meters) below Naica mountain in the Chihuahuan Desert, this astonishing cave was discovered by two miners only in the year 2000.
A sort of south-of-the-border Fortress
of Solitude, Mexico's Cueva de los Cristales (Cave of Crystals)
contains some of the world's largest known natural crystals -
translucent beams of gypsum as long as 36 feet (11 meters).
