Crystal Giants in the
This book contains text and numerous color photos, including 18 large ones, some occupying two full pages. Cave map. From the back cover:
"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 discovered by chance, fragile and mysterious; something we risk to lose at any time. And that will soon turn inaccessible again, hidden in the heart of the earth.
"Naica's Cave of the Crystals is a small window into the immense geological time; a window man can now open thanks to a new, exclulsive technology. A high risk 'astronautics' exploration, in order to understrand, study, document, and save. Before it becomes too late."
