For a civilization that has been gone for centuries, it’s incredible that scientists are still uncovering secrets of the Mayans. In the August issue of National Geographic, some more of the Mayans secrets are revealed about their relationship with natural water wells, otherwise known as cenotes. Underwater archaeologists Guillermo de Anda and Arturo Montero have been exploring these underwater caves in hopes of learning what their relationship might have been with the Mayans. Their theory is that the Mayans might have used the caves as sundials, a place to hold sacrifices, and where they determined where buildings or sites were constructed. It will be interesting to see what the pair of archaeologists continue to uncover as they continue on the quest to uncover the many mysteries of the Mayan culture.
