Gypsum crystals are common in some of the dryer parts of the cave. Gypsum, a mineral containing both calcium and sulfur, sometimes takes the form of needle-like crystals that radiate from clusters on the floor of the cave; in other cases, gypsum resembles puffs of cotton, or forms clusters of curved or coiled crystals called gypsum flowers.
