A geological wonder of immense proportions and intense beauty can be found in the Chihuahuan Desert of Mexico… 1000+ feet below the surface. The Cueva de los Cristales - the Giant Crystal Cave – is also one of the most deadly environments on the planet.
For his BBC series How Earth Made Us, filmmaker Paul Williams discovered firsthand the scorching heat and toxic setting that has kept humans away from the crystal phenomenon. ”The coolest part of the caves is your lungs and so moist air starts to accumulate in them… leading to respiratory difficulties.”
Cueva de los Cristales is the incarnation of our most awesome science fiction imaginations – Jules Verne’s Journey to the Centre of the Earth, Superman’s Fortress of Solitude. At about the same time as humans first ventured out of Africa, these crystals began to slowly grow. For half a million years they remained protected and nurtured by a womb of hot hydrothermal fluids rich with minerals.
It wasn’t until 2001 that miners, searching for lead, eventually penetrated the cave wall and brought it to light.
