Ersalibuti, Natural sinkhole in Timor-Leste
Ersalibuti is a sinkhole in limestone terrain where surface water drains into a vertical shaft and underground passages. The opening connects to a natural water system that moves through the rock layer below.
The formation developed over millions of years as acidic water gradually dissolved the limestone, creating vertical and horizontal passages underground. This geological process shaped the landscape that visitors see today.
Local residents of Timor-Leste incorporate the ponor into their traditional narratives about water circulation and natural resource management in the region.
Visiting requires technical climbing skills and specialized gear, as the vertical shaft demands experience with caves and steep drops. This site is suitable only for those with proper training and equipment.
The location of this ponor at -8.895499 latitude creates specific water flow patterns during seasonal rains, affecting the underground hydrogeological system.
