Beauf

Vertical cavity located in Añemercandia/Añebakardia with a first pit of 30 m, with a window at -20 m, and an ascending gallery with airflow. A new pit of 12 m allows continuation through another of 40 m with unstable debris, until at -73 m a window opens onto a parallel pit. A new vertical of 10 m and a clearance with a strong descending airflow lead to a double fractionation of 10 m; then, a climb and a clearance at two points over 10 meters of length allow passage to a pit of 65 meters, with a bottom covered in cobbles. A side passage leads to the continuation of the fracture, with a pit of 52 meters and a stepped structure of 8 meters over a pit of 28 meters, with the bottom located at -282 depth.
