This shaft is situated near a solitary tree on the edge of a cliff. The tree can be seen to the right of the path leading from the Cabanas de Llau to Tamamdon, when the Tamandon-Oceno valley comes into view. The large Calluenga (Calvenga) entrance can be seen on the opposite side of the valley KCG: 2km up the Trescares valley and 300m up the eastern side, following a sandstone boudary


The entrance is positioned on a shoulder, near the head of the valley on the eastern side. The entrance depression features the junction of the sandstone and carboniferous limestone trending down the the dip for 10m

The funnelled depression is vegetated for 5m to another 3.5 enlarging into a rift


The entrance rift continues at 40 degrees to the floor of a jointed chamber and a passage. Formations are scarce apart from a small quantity of flowstone at the base of the boulder floor.
The width of the passage is 7.5m but the ceiling is difficult to estimate due to additional avens in the north and south directions
The boulder slope continues down to a further drop trending the same way as the jointed passage. The pitch leads to a decorated chamber with no apparent way on.
