Avenc Nº1 de Can Verdeguer

On 1 May 1973, Mr. Narcís Rucabado, then president of the Geography and Natural Sciences Section of the Centre Excursionista de Catalunya, together with his son, accompanied Oleguer Escolà (ERE – CEC) to three pits that they had recently found on one of their morning excursions from Capellades. These were the three entrances of what was called Avenc nº 1 de les Clivelleres. In a nature guide to Mediona (E. Rafecas, 1995) mention is made of this one and of the cavities numbered 2 to 4, calling them avencs del Verdaguer (sic).

But... it turns out that colleagues Jordi Navarro and Montse Mañosa, while searching for documentation of the area, were able to locate, in an old bulletin of the Centre Excursionista de Sabadell, a note relating the true first exploration of this pit. Three members of the Speleology Section of the CE Sabadell (F. Barceló, M. Garriga and J. Sallent), accompanied by three people from Sant Quintí de Mediona, explored the pit on 29 August 1954. In this brief account they comment on the difficulties of the exploration due to a series of block falls that had no serious consequences. They also mention having made a survey and that they calculate that the cavity is 37 m deep and 66 m long.

In view of these developments and also that in Mediona they know them by the name of the mas de Can Verdeguer, we have decided to rename the group of cavities with the name of the mas that gives its name to the nearby housing estate. We keep the name Clivelleres as a synonym and continue with their order number so as not to create further confusion.
