CENOTE

(from Maya dz'onot), natural well or reservoir, common in the Yucatn Peninsula, formed when a limestone surface collapses, exposing water underneath. The major source of water in modern and ancient Yucatn, cenotes are also associated with the cult of the rain gods, or Chacs. In ancient times, notably at Chichn Itz, precious objects, such as jade, gold, copper, and incense and also human beings, usually children, were thrown into the cenotes as offerings. A survivor was believed to bring a message from the gods about the year's crops.
