Formation of cenotes
The formation of cenotes is a geological process that results in the creation of these unique natural formations. Cenotes are typically formed through the dissolution of limestone or other soluble rocks over thousands of years.
The process begins with rainwater seeping into the ground and slowly working its way through cracks and fissures in the earth’s surface. As this water travels through the ground, it gradually dissolves the limestone, creating underground cavities and tunnels.
Over time, the ground above these underground cavities may collapse, creating a sinkhole. These sinkholes can vary in size and shape, with some forming cylindrical shafts that lead directly down into the underground caverns, while others may have more irregular shapes.
Once the sinkhole is formed, it can fill with water from various sources. This can include rainwater, as well as groundwater that rises up from underground rivers or aquifers. The resulting cenote is a natural pool of water that is often clear and blue due to the filtering effect of the surrounding limestone.
Cenotes can be found in various parts of the world, but they are particularly common in the Yucatan Peninsula of Mexico. The region’s unique geology, which consists of a thick layer of limestone, has resulted in the formation of extensive underground cave systems and a vast network of cenotes.
