Cavity with 80 metres of vertical drop next to the Lizarraga road, with an entrance in a doline and several pits and interior chambers.
Descrizione
Morfologia
The entrance opens at the centre of a doline about 4 metres in diameter. The cavity presents a 10-metre vertical and a strongly inclined debris platform, followed by a new drop of 20 metres. The E-W orientation leads to a large chamber of 30x20x30 with a pit in the very long debris cone. In the northern part there is a new pit opened in a joint, 20x4x25 metres deep, which leads to a gallery covered with blocks and continuing westward for 25 metres, ending in an ascending clay ramp, with a narrow window at the foot of the ramp. The total vertical drop is 80 metres.
