The name of this cave in Chihuahua, Mexico makes it pretty clear what you are going to find inside of it: crystals. Like really, really big selenite crystals. And when we say big, we mean over ten feet in diameter and about 50 tons. The largest one ever found was 39 feet long and 13 feet wide.

The inside of this cave looks like a deadly chamber on set of an Indiana Jones movie. But just like the Mendenhall Cave, you can’t go see this one, either. Temperatures can reach a scorching 136 degrees Fahrenheit and humidity is always above 90%. Without proper protection, you would only withstand a few minutes before begging for mercy.
