Vertical cavity in the lower Añelarra valley, with an entrance in an N-S fissure and several verticals down to 38 m.
Descrizione
Morfologia
The entrance opens in an N-S fissure, in grey limestone, with a sloping entrance and a great deal of scree. The first vertical is 16 m, with a debris cone at its bottom. About 4 m above the bottom a window opens that coincides with the axis of the fault, which soon becomes impassable, as does the meander at the bottom.
Progressione
After the first 16 m vertical, one reaches a new shaft of 17 m, with the end at 38 m.
Storia
1984 IPV Estella.
Paleontology: remains of Spanish ibex, found in the meander at the bottom.
