The Cave of the Crystals
Cueva de los Cristales (Cave of the Crystals) is a cave connected to the Naica Mine 300 metres (980 ft) deep in Chihuahua, Mexico.Naica is a lead, zinc and silver mine in which large voids have been found, containing crystals of selenite (gypsum). The main chamber contains giant selenite crystals, some of the largest natural crystals ever found. The cave's largest crystal found to date is 11 m (36 ft) in length, 4 m (13 ft) in diameter and 55 tons in weight. The cave is about 27 m (89 ft) in length and 9 m (30 ft) in width. The cave is extremely hot with air temperatures reaching up to 58 °C (136 °F)[2] with 90 to 100 percent humidity. The cave is relatively unexplored due to the extreme temperatures and high humidity. Without proper protection people can only endure approximately ten minutes of exposure at a time.
The chamber holding these crystals is known as the Crystal Cave of Giants, and is approximately 1000 feet down in the limestone host rock of the mine. The crystals were formed by hydrothermal fluids emanating from the magma chambers below. Read more about it on MFS,with videoclip.
