Cave of Crystals

Naica, Chihuahua






La cueva está cubierta de cristales masivos, algunos alcanzando hasta 40 pies de largo. La cueva es extremadamente caliente, con temperaturas del aire alcanzando hasta 58 grados centígrados con 90-99 por ciento de humedad. La cueva es relativamente inexplorado debido a estos factores, sin la protección adecuada la gente sólo puede soportar 10 minutos de tiempo de exploración.


La cueva está conectada a la mina Naica cerca del municipio de Saucillo. Los cristales se encuentran a casi mil pies de la superficie de la mina.


Cave of the Crystals or Giant Crystal Cave (Spanish: Cueva de los Cristales) is a cave connected to the Naica Mine at a depth of 300 metres (980 ft), in Naica, Chihuahua, Mexico.

The main chamber contains giant selenite crystals (gypsum, CaSO4 • 2H2O), some of the largest natural crystals ever found. The cave's largest crystal found to date is 12 m (39 ft) in length, 4 m (13 ft) in diameter and 55 tons in weight. When it was accessible, the cave was extremely hot, with air temperatures reaching up to 58 °C (136 °F) with 90 to 99 percent humidity. The cave is relatively unexplored because of these factors. Without proper protection, people could only endure approximately ten minutes of exposure at a time.

The cave was discovered in April 2000 by the brothers Juan and Pedro Sanchez while drilling in the mine. As of October 2015 the mine had reflooded, and the cavern filled once more with the water rich in minerals required for the crystals to grow.

A group of scientists known as the Naica Project have been involved in researching these caverns.
