Read this story about the formation of these giants crystals (36 feet long and can weigh 55 tons) made of gypsum that lie in caves about 1000 feet under a mountain in Mexico. The temperature in the caves is around 136 degrees F and the caves are usually filled with water, but the mining operations keep pumping it out.
