Cova-avenc del Cim de l'obaga del Pollo

The entrance, in a vertical position and 4.2 x 4.8 m (width x height), gives way to a wide chamber of 15.5 x 6.8 m with the ceiling at 4.8 m high. The E wall of the chamber is formed along the main joint; therefore, next to this wall we find a collapsed fracture that gives way to some pits. The S end of the aforementioned fracture also gives continuity to the cave after overcoming a narrowing. The S zone is formed by a narrow joint. The N zone of the fracture is collapsed and gives way to a wide 11 m pit. At its base we find a gallery 1.7 m wide. Towards the N we find a new 5.5 m pit that leaves us in a narrow little room where the cavity still continues through a narrow vertical passage that reaches 20.6 m deep.

Without descending to the bottom of the drop we access a level where the walls appear covered in concretions and which continues for about 10 m.

This S gallery begins ascending and then descends and overcomes an 8 m drop followed by another of 7 m that leaves us in a narrow zone that closes but where an appreciable air current is noticed. On its S side a narrow fracture emerges that ascends a series of narrow drops and reaches the entrance chamber again. This point is very close to the tip of the climbs in the Avenc del Cim de l'Obaga del Pollo.
