Entrance collapse followed by a cleared passage, two pits and a terminal chamber reached after a dynamited squeeze.
Description
Morphology
The entrance is a fine collapse. The bottom is too narrow.
Progression
A 4-metre passage is cleared to reach a 10-metre pit, followed by a descending low passage leading to a new 8-metre pit. A traverse in the middle of the pit gives access to a climb that bypasses the previous squeeze and continues into a small fault-guided meander. A dynamited squeeze leads to the terminal chamber.
