A 61 m deep pit with the largest entrance in Catalonia, in the Priorat.

Caratteristiche

Località

From the village of la Torre de Fontaubella you must take the TV-3001 road towards Marçà and at approximately km 5.3, a track branches off to the right that climbs through old terraced fields and woodland, overcoming more than 60 metres of elevation gain to the pit entrance.

Having carefully examined the ICC cartography, we have confirmed that the entrance of the cavity lies more than 90% within the municipal boundary of la Torre de Fontaubella and a small stretch, the northernmost one, within that of Pradell de la Teixeta, where the entire cavity had been placed in earlier catalogues.

Descrizione

Morfologia

Large, almost circular entrance of 22 x 26 metres that gives access to the impressive shaft. From the lower lip the vertical drop is 36 metres, landing right in the middle of the great chaos of blocks that occupy the entire floor.

A very didactic example of a collapse pit. In the lower chamber the bulging of the stratification and its tendency to detach can be observed.

It is the pit with the largest entrance dimensions in Catalonia.

In the two first known surveys the 0 datum was placed at the upper lip, with which the total depth increased by some 6 metres, but if we are to follow the recommended regulations, the 0 datum must be placed at the lower lip.

Progressione

Descending among the blocks in a N direction, one reaches a chamber, outside the vertical of the shaft, that reaches the -52 level. Continuing in a S direction from the landing point, the ramp between blocks places us at the point of maximum depth of the cavity (-61 m).

Storia

A cavity known since time immemorial by the people of the region and mentioned in the oldest speleological catalogues (P. Madoz; C. del Prado; Puig y Larraz,...). The first exploration was carried out on 20 July 1899 by N. Font i Sagué during a campaign dedicated to different Tarragona districts.

Visited later by different generations of Catalan cavers, it is not until 1970 that members of the SIE – CEA carry out the survey of the pit and it is published for the first time.

As for the toponymy, the old catalogues call it Avenc de Fontaubella, even Font i Sagué in his catalogue calls it thus, although after exploring it, in his work he mentions it as Avenc de la Torra.

Joan Ferraté, in his work “Espeleologia de les comarques tarragonines” cites it already as Avenc de la Torre de Fontaubella and also as Avenc de la Torre.

Recently the oldest form has been recovered, although it must be said that the people of the area simply call it: l'Avenc.
