Sistema Zacaton

El Zacaton sinkhole, Mexico

Unique karst field created by thermal acidic waters heated by volcanic heat. Contains the world’s deepest water-filled sinkhole, the 339 meters deep El Zacatón sinkhole with 319 meters deep lake, and floating islands.

Most likely it hides unknown life forms, not investigated.

Poza del Caracol, Sistema Zacaton
