Belize: The Underworld
Today, Belize has a huge system of caves to explore and tourists often visit at least one cave while in Belize. Now, you might think that these caves are cramped and dark, but most are massive. There are even underground rivers that flow through these caves, allowing visitors to lazily float through then via inner tube.
The Crystal Maiden is the skeleton of a teenage girl who was most likely a sacrificial victim. This skeleton dates back more than 1,000 years. Her bones now have a shimmering, crystallized appearance due to the carbon build up in the caves mentioned above. She has quite literally become part of the cave itself.
