Mina Superior de la Canal

In August 1910 Faura i Sans accompanied the biospeleologists Jeannel and Racovitza during their excursions to the Conca de Tremp. Faura recorded an oral account of a cavity at Llastarri that they call Forat Negre.

The following year, specifically on 18 June 1911, Jeannel and Racovitza reached Llastarri and visited the Mines de la Canal, where they made an important collection of fauna.

For many years, until 1979, there was no news of these mines, and even now we do not know of the existence of the Forat Negre. This relocation of the cavity was carried out by the biospeleologists Oleguer Escolà and Jordi Comas, in search of the fauna collected by Jeannel and Racovitza. Subsequently many more visits followed, especially by J. Fresneda, all with biospeleological purposes.

On 27 March 2019 a team made up of members of the GELL – CE Lleida and the ERE – CEC visited the cavities while carrying out the relevant cataloguing work.
