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 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.
A group of scientists in the Naica Project have been studying these caverns.
In 1910, miners discovered a cavern beneath the Naica Mine workings, the Cave of Swords (Spanish: Cueva de las espadas). It is located at a depth of 120 metres (390 ft), above the Cave of the Crystals, and contains spectacular, smaller (1-metre (3 ft 3 in) long) crystals. It is speculated that at this level, transition temperatures may have fallen much more rapidly, leading to an end in the growth of the crystals.
Giant Crystal Cave was discovered in April 2000 by miners excavating a new tunnel for the Industrias Peñoles mining company located in Naica, Mexico, while drilling through the Naica fault, which they were concerned would flood the mine. The mining complex in Naica contains substantial deposits of silver, zinc and lead.
The Cave of Crystals is a horseshoe-shaped cavity in limestone. Its floor is covered with perfectly faceted crystalline blocks. Huge crystal beams jut out from both the blocks and the floor. The crystals deteriorate in air, so the Naica Project attempted to visually document the crystals before they deteriorated further.
Two other smaller caverns were also discovered in 2000, Queen’s Eye Cave and Candles Cave, and another chamber was found in a drilling project in 2009. The new cave, named Ice Palace, is 150 metres (490 ft) deep and is not flooded, but its crystal formations are much smaller, with small “cauliflower” formations and fine, threadlike crystals.
