Located in Chihuahua, Mexico is the largest known crystal cave in the world. Known as the Giant Cave of Crystals, this mystical place of wonder contains crystals of selenite (gypsum) that have grown to nearly 50 feet tall, and weighing nearly 55 tons. Within the Naica mountains nearly 1,000 feet down, are these pockets of giant crystals.
Discovered in 2000, this find has become one of the most important geological finds in history. Hydrothermal fluids formed the crystals. They've managed to survive for a millennia by a constant heat of 136 degrees Fahrenheit and a mineral rich water that helps to make the crystals grow.
The cave is so intense in heat, with temperatures soaring to 150 degrees Fahrenheit, and a humidity of 100%. The crystals are literally enveloped in steam. So hot is the cavern, that people can only withstand the heat for minutes at a time before severe loss of mental functions become present.
Apparently a man who tried to steal some of the crystals lost consciousness due to the excess heat. A crystal he was chopping lose fell and pinned him. He was later found roasted to death.
Scientists who study the caves come prepared when trying to deal with the inhospitable caves. Plans of conditioning the caves are now being undertaken when the caves will become open to the public.
Serious action is now being taken to prevent further removal of these crystals, although some are held in the Smithsonian Institute.
