Name: Cave of Crystals

The Cave of Crystals is an underground cavern filled with tree-size gypsum crystals, including some of the largest natural crystals ever found. The cave is located around 980 feet (300 meters) deep and is connected to a lead, zinc and silver mine in Naica, 65 miles (105 kilometers) southeast of Chihuahua City. The mine was flooded almost 10 years ago after workers accidentally broke into an aquifer, but the Cave of Crystals sits higher in the ground, meaning the water didn't reach it.
