Cenote Zaci in Valladolid, Yucatan, Mexico
(from Mayan dzonot
) is a collapsed underground limestone cavern
that contains water
. They are found throughout the northern part of the Yucatán
peninsula and are part of the underground river
system. Owing to the lack of any surface rivers in this area and the irregular rainfall, they were particularly important as a water source for the ancient Maya and played an important part in their religious ceremonies.
