The caverns became flooded over time as a result of groundwater seeping in. This water was rich in gypsum minerals, and the heat generated by the magma worked like a cooker, maintaining a steady heat for over 500,000 years. The gypsum in the water then transformed into the translucent selenite crystals that we see today.
