Is closing forever the window which just 15 years ago had opened on the fantastic world of Naica and its gigantic crystals. A sudden coming of water, of a size that can not be controlled, has caused the rapid progressive flooding of the Naica mine (Chihuahua, Mexico) inside which had been discovered some caves with the largest gypsum crystals in the world.

The mine was then abandoned and the caves will be in a few weeks under almost 150 meters of water: no human eye can see them ever more. It is a great loss not only for speleology but for all mankind. Remains the tremendous work of research and documentation that the Association La Venta, together with Speleoresearch and Film of Mexico City, has coordinated between 2006 and 2010 and allowed on one hand to document directly, with thousands of photos and hours of film, all aspects of this incredible world and on the other led a team of scientists from three continents to study every detail of these caves. Although unable to directly see these wonders of nature, future generations will then have memory of Naica and its giant crystals and especially thanks to the publications that La Venta has already produced and will produce in the near future on these amazing caves, now lost for always.
