This unusual system of geological features consists of Cenote Azufrosa – large sinkhole with double bottom and La Cristalina – cave with spring. These natural wonders belong to the unique karst system of Sistema Zacatón.

Sistema Zacatón is area with incredible characteristics unparalleled in the world. In total area contains some 20 unusual features – sinkholes, caves, springs created by deep groundwater heated by volcanic processes. Karstification processes here continue today as well – acidic groundwater continues to strip away the limestone and deposits it in unusual travertine formations.

Cenote Azufrosa

Cenote Azufrosa at the first moment seems to be just a shallow pool of light blue colored water. Water in this pool though is highly sulfurous, with the characteristic odour of rotten eggs. Sulfur here precipitates and floats on the surface of water. Water of this lake discolors and tarnishes metals.

Geophysical research shows that the bottom of this pool is far from usual- it is a travertine lid with deep, isolated waterbody below it.

La Cristalina

At the southern rim of this cenote is located La Cristalina – unusual cave with deep blue water in it. This enormous spring has been dived up to 50 m depth in 1990. Sometimes it is considered to be a discharge of the nearby Las Quarteles caves.

Temperature of water in the spring is 30° C.

Few countries of the world can offer such array of unique and astounding attractions as Mexico.

Area of this country was cradle of several highly developed indigenous civilizations and some regions in the country are dotted with remnants of ancient cities with temples, palaces and pyramids.

Sinkholes

Hypogene Karst Regions and Caves of the World


This book illustrates the diversity of hypogene speleogenetic processes and void-conduit patterns depending on variations of the geological environments by presenting regional and cave-specific case studies. The cases include both well-known and newly recognized hypogene karst regions and caves of the world. They all focus on geological, hydrogeological, geodynamical and evolutionary contexts of hypogene speleogenesis.
