This prominant feature is seen to the west of the main road from Beranga to Hazas, about 180m south of the motorway viaduct. A cave, first explored by Matienzo cavers in 1977 and the detail sketched into the 1977 logbook, page 99. The length above is a guess and could be quite a bit longer. It is presumed that the entrance is one of the holes above the spring.
