The Giant Crystal Cave in Mexico was discovered in 2000 when miners pumped water out of a cave, revealing massive selenite crystals. The cave's extreme conditions, with temperatures around 58°C and nearly 100% humidity, make it inhospitable and challenging for scientific research. The crystals formed over half a million years due to the slow transformation of anhydrite to gypsum under stable temperatures. Other caves in the area have smaller crystals due to faster cooling. The cave's unique environment is ideal for crystal growth, and the crystals will continue to grow if the cave is reflooded.
