Mayan Underground Pyramids

A labyrinth containing stone temples and pyramids, within 14 caves—some of which are underwater—have been discovered on the Yucatán Peninsula in Mexico.

This is an amazing discovery, and hopefully National Geographic will be providing more details in the near future. The article says:

According to Maya myth, the souls of the dead had to follow a dog with night vision on a horrific and watery path and endure myriad challenges before they could rest in the afterlife.

In one of the recently found caves, researchers discovered a nearly 300-foot (90-meter) concrete road that ends at a column standing in front of a body of water.
