Cenote diving will bring you a new perspective on the underwater exploration. Known by the Mayas to be the entrance door of Xibalba (the death world), it is under our feet that lays the world’s biggest underground river system. Sac Actun – Dos Ojos System is the longest underground river system recently found to connect and run for a total of 215 miles.
What are cenotes?
At some point in time, sharks and whales were swimming where we now eat breakfast today. Millions of years ago, sediments and coral reef started to accumulate and slowly created what we call today, the Yucatan peninsula.
Then, 65 millions years ago, a giant asteroid fall on earth, creating the Chicxulub crater, which has a diameter of over 180 km, leaving the surroundings in a giant dust cloud. Scientists believe that this impact might have been the cause of the demise of 50% of the species leaving back then, including the dinosaurs. The sea level went down and all the particles impacted the surfaces of the ground, leaving the Yucatan peninsula like a Gruyere cheese.
Then, 125 000 years ago, the planet lived its last heat period (it is almost as hot today) and the seas levels went up, filling the ”cheese wholes”. This porous calcareous ground also acts like a filter with the rain, so the ”cheese wholes” also slowly fill with rain water, which creates the Cenotes we know today, made of a mix of salty and fresh water.
Diving the cenotes is traveling through a giant page of our world history and even today, we still find lots of artifacts, bones and fossils in them.
