Cavity very well known to the people of the area. The first speleological visit of which we have a record was made by members of the SIE – CEA in November 1973. A few months later, members of the GES-CMB, during the work of compiling the Garraf catalogue, visited it again.

Our friend Joan Borràs mentions a first exploration by Rafael Amat i Carreras in the 20s of the last century, attributing to it a depth of 30 metres and that it seemed to have been covered over. We have no reference to this pit in the whole of Amat's work and we believe there was a confusion with a citation in Font i Sagué's catalogue where he mentions an avenc de la Figuerota, 32 metres deep and which he places in the coastal area of Garraf, known to the miners who worked at la Falconera. Of this cavity there has never been any further reference and it may be an error or a bad transcription.
