The shallow, rounded Atascosa Pool belongs to the unique Sistema Zacatón. This muddy, rounded pool has diameter of some 120 m. It dries up only at very extreme droughts and most likely is fed by some springs.

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.
