Mexico's Yucatan Peninsula is dotted with thousands of caves that once housed prehistoric people and later became sacred to the Mayans. German archaeologists and filmmakers are currently involved in a project to explore with modern imaging technology and make a 3-D film of this underwater labyrinth.
A person died here hundreds of years ago. His body fell into the flooded cave and sank into the water. His flesh gradually separated from his bones. Today, he stares at divers out of empty eye sockets. His skull seems to be pushing its way out of the soil, as if he were trying to rise from the dead, to rise up from the sand, shake the tiresome sediment from his bones and escape from the silent darkness.
The others would probably want to follow him, because he isn't alone. The remains of more than 125 people lie in the Las Calaveras cenote. No one knows how and why the bodies got there, whether the people died at the same time or the bodies accumulated over the centuries.
