The rounded sinkhole - Laguna Colorada - belongs to the unique Sistema Zacatón. Laguna Colorada is filled with emerald colored water and possibly is quite deep. Like many other cenotes it though has steep sides covered with dense vegetation and thus is hard to access and investigate.
Sistema Zacatón is area with incredible characteristics unparalleled in the world. In total this 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.
