It seems that the entrance was opened accidentally when the track was built, since it lies right next to it. The first report is given by members of the SIEP – CE Poblet (Barcelona) who one may suppose explored it in 1978, although they only mention it in a collection of cavities of the Garrotxa (Bol. SIEP no. 10 – 1978) as Avenc de la Font del Bosc de Ramadans and attribute to it 10.5 metres of depth. Later, in a new update of the map of the Garrotxa (Ed. Alpina, 1990) the list of cavities is enlarged and this pit appears -badly located- without providing any further data.

It is not until November 2016 that members of the EC Gràcia and the GE Badalona locate it and carry out the corresponding cataloguing work.

Note from Espeleoíndex: This cavity was not included in volume 4 of the Catàleg Espeleològic de Catalunya (1980) because we had absolutely no reference, we only knew the name and the depth from a list of activities, I believe, if my memory does not fail me, of the Grup Espeleològic d'Olot which had explored it some time before. Those of the SIEP (one of them, F. Talavera, was on the Catàleg team) included it in the list of cavities. (JM. Miñarro)
