Narrow cavity at the entrance below an east summit, comprising a sculpted step, a letterbox entrance and a vertical shaft 2.5 metres in section.
Description
Morphology
The entrance (2.5 m x 0.6 m), below the east summit, opens onto a small, well-sculpted, rubble-strewn step. It is followed by a very narrow, inclined letterbox entrance (0.7 m x 0.4 m) that opens directly into the very centre of a fine vertical shaft 2.5 metres in section. This ends at the top of a flat rubble cone where a narrow, extremely corroded and jagged continuation opens.
Other details
It seems that, given the narrowness of the entrance, this cavity has not been visited, and moreover we are not aware of any account although it opens on an exposed summit.
