This cavity is divided into three zones according to its characteristics. Thus we have: The Fossil Network of the Sima de Cueto which is characterized by having huge corridors in which there is no water around it and the ground is made up of large stone blocks which makes it difficult to transit through this area. Another section is the Intermediate Network which is made up of a large number of caves and labyrinth-like paths, these suppose an excavation after the waters and has several levels, these connect the Sima del Cueto and La Coventosa. The third section in the Coventosa Gallery, which is located next to the previously described labyrinthine area, communicates with almost all the galleries as well as with the Cubera spring.
