Cave description:
The small entrance is located on the left hydrographic side of the narrow valley where the river that sinks in Shui Xiong Dong (located 1 km far) runs, just above the bottom of the valley. The initial section of the cave is inactive,whereas the central and ending sections are active, at least for some periods of the year. In particular, the morphology of the lowest section is typical of active hydrology. Six soil samples were collected in the thick alluvium located uphill of the active karstic area; they were to be dated by the analysis of pollen content.
