WORLDKINGS - Worldkings News - Giant Crystal Cave (Mexico): World's largest crystal cave lying below the surface of the Earth

08-05-2020

(Worldkings.org) Giant Crystal Cave, Mexico is the world's largest crystal cave lying below the surface of the Earth.

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 can only endure approximately ten minutes of exposure at a time. The cave was discovered in April 2000 by 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.
