Avenc de la Bassa de la Llacuna

A small step places us at the entrance of a sloping shaft 12 metres; behind us the wall is completely smooth. An irregularity in the slope of the step links directly with the dome of a shaft 17 metres, wider and more comfortable. At the base, where we find materials from the artificial digging open, a descending gallery begins that, after overcoming some short ledges, communicates with a shaft 15 metres of jointed structure and its floor is no more than three metres.
