The information below has been roughly translated from the French, Spéléo-Club Dijon reference, Simonnot G, 2018.

   Below Vallina, 150 m south of the Cueva Cisterna . The sink is impenetrable but nearby there is a pitch of 5 or 6 m with earthy walls (no obvious draught, recent collapse?) 450,027 4792,483? -4 +
The loss is in contact with the summit of the sandstones (sandstone of Llaneces) and the base of the limestones of Vallina. Like the flows of the Cueva de la Vallina it must probably feed the hydrologic system "Comellante"
