What are Cenotes?
The Yucatan Peninsula is a limestone platform which was created millions of years ago. Throughout various glacial periods, the ocean level has varied, and this platform found itself submerged by water. When the level of the ocean drops again, the caves begin forming. The rain falling on these formations dissolves through the rock the carbonic acid from the soil and leaves in putrefaction. This carbonic acid mix carved the fragile rock, creating underground passages in which water would find its way back to the ocean. In this process stalagtites and stalagmites were also formed. During the last glacial period, the oceans were 100 feet below their actual level. Around 18,000 years ago, the ice started melting and the ocean rose to the level we know now, flooding the passages and generating a wide underground river system like nowhere else on earth.
