Caratteristiche

Località

From the Coll de la Creu, near Lliurona, we follow the Espinau path; on reaching the Teuleria, we take the middle path, soon passing the Pla del Perer and further on, level with the font de l'Arç, we find a track coming in from the right. At this point we can leave the vehicle, since about 150 metres further on, on the left, a path sets off through the woods up to the Tossa d'Espinau. The path passes near the small col that separates the Tossa from the mountain ridge, where it begins to level out. Taking a direction parallel to the ridge, we continue for about 100 metres more before leaving it and heading for the ridge on our left; at the top of the ridge we find an extensive limestone pavement and, shortly after starting the descent on the N slope, we find the cave, at the foot of a step and in a depression half hidden by vegetation.

The Espeleodijous colleagues went from Beuda to find the same track via the South slope (camí d'Espinau) and walking back up from the Baga del Carig.

Descrizione

Morfologia

The entrance opens at the bottom of a depression, giving way to a -3.5-metre drop, reaching a widening from which a -10.3-metre pit descends. If we enter via the gallery above the pit, we can also descend from here with a drop of -9 metres. Once in the lower gallery, to the NE, there is a lower passage that had to be cleared which leads us to the base of the pit. To the SW, the main gallery ends at 38 metres depth. In the middle of this last stretch of the main gallery, three descending routes begin that reach -38, -44, and via the deepest of all, overcoming two consecutive drops of -3.8 and 4.4 metres, the lowest point of the cave is reached, -55 metres. The cave is structured along a main fissure running NE-SW. The average width of the galleries ranges between 1 and 1.5 metres, except for a widening of about 6 metres in the middle stretch of the gallery.

Concrezioni

In the middle stretch of the gallery, where there is a widening of about 6 metres, we can observe the main lithogenic processes of the cave.

Progressione

Care must be taken when exploring the cave due to the presence of unstable blocks.

Storia

The cave was located in 1983 by J. Cuenca (GEB) together with another colleague. In 1985 several members of the GEB and the ECG, while prospecting, pass by the entrance and enter the cave with a torch, stopping at the head of the pit as they had no equipment. Finally, on 17 December 1988 the GEB and the ECG carry out the exploration, except for the final “ramonage”. Fifteen days later, a large group from the ECG carry out the survey down to -46 metres and 245 metres of passage.

In 1997, the GEB carries out a new re-survey of the cave, finding new continuations, reaching a depth of -55 metres and 296 metres of passage.
