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.
Sinkhole with secret
Surface of Poza Garapata – a rounded sinkhole – is covered with dense vegetation. It is hard to access – sides of the sinkhole are steep and covered with even more dense, thorny vegetation. As it is usual in the thickets of Sistema Zacatón, here are many ticks – hence the name of sinkhole.
Most likely the even bottom if this seemingly simple landmark is just a few metres thick layer of travertine with enormous body of clear water below it – not too far is the unique Poza Seca – very similar sinkhole covered with travertine lid and hiding unknown organisms in the water below it.

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.
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.
The Encyclopedia of Caves and Karst Science contains 350 alphabetically arranged entries. The topics include cave and karst geoscience, cave archaeology and human use of caves, art in caves, hydrology and groundwater, cave and karst history, and conservation and management. The Encyclopedia is extensively illustrated with photographs, maps, diagrams, and tables, and has thematic content lists and a comprehensive index to facilitate searching and browsing.
