A 30-metre-deep pit at Pla d'Ardenya, Vallirana, explored between 1968 and 1973 and cleared in 2017.

Caratteristiche

Località

Going along the track between the Pla d'Ardenya quarry and the avenc Pompeu Fabra in the direction of the Creu d'Ardenya, we will come to a crossroads that on the left takes us to the avenc T-38 and that leads to the track of the poliè of Pla d'Ardenya. From the aforementioned crossroads, we will follow the track in a S direction, towards the Creu d'Ardenya for 32 metres; at this point on the left of the track, we will find a path that in 10 metres will place us at the mouth of the pit.

Descrizione

Morfologia

The mouth gives access to a shaft 1.84 metres deep; at the base, a slope takes us to the head of a shaft divided into two parts, with a rock ledge in the middle, the first section 2.89 metres and the next, more vertical, 6.84 metres; at the base we find two superimposed horizontal passages of 3 and 5 metres respectively; on the opposite side a short descending gallery takes us to a perpendicular joint where we will turn right almost 180 degrees to go down to a small chamber where we find the small mouth of a shaft 5.28 metres deep, which places us at the base of a sloping gallery. Continuing down we find a narrow passage and a steeply sloping gallery that gradually narrows until it becomes impassable. From the base of the aforementioned shaft, we will climb back up the gallery and reach a shaft 2.63 metres deep; this point forms a kind of chamber 6 metres long and with the ceiling at 5.23 metres, with abundant formation; at the other end of the chamber we find a new shaft 5.87 metres deep that begins with a steep ramp. At the base we find a passage between formation that takes us to a small chamber where we find a narrow shaft 1.10 metres deep where for the moment it is not possible to go further.

Concrezioni

The chamber 6 metres long and with the ceiling at 5.23 metres has abundant formation, and at the other end a new shaft 5.87 metres deep begins with a steep ramp; at the base there is a passage between formation.

Progressione

On the date the visit was made, October 2019, the gas meter detected slight hypoxia (17.2).

Storia

This is one more of the many cavities explored at Pla d'Ardenya between the years 1968 and 1973 by a group of speleologists residing in Vallirana and who belonged to the ERE of the AEC; in 1976 these took part in the founding of the Centre Excursionista de Vallirana.

Of the avenc del Xiclet, until 2016 only the first 4 metres were known, since an accumulation of blocks prevented progression.

On 25-9-2016 members of the EspeleoCorb de Corbera de Llobregat reviewed the cavity and confirmed that its clearing was feasible. On 21-1-2017 they began the work which, after several days of clearing, would end in May 2017 reaching 28 metres of depth; in these tasks Alberto Sánchez, Jordi Boira, Amadeu Avià, Jordi Zambudio, Isis Barrio took part, with the collaboration of Laura Besolí, Francesc Alarcón, and Ignasi Morros.

In 2017 the EspeleoCorb released a sketch of the cavity.

During the years 2021 and 2022, Ignasi de Yzaguirre and Sofia Bengoetxea (GERS de l'AEM) were clearing the North-east end of the bottom of the cavity, with the only result of reaching the -30 metres depth level.
