History

The only reports we have are of an exploration carried out around the year 1970 by a group, possibly from the SIRE – UEC Gràcia, among whom was Pau Pérez, who provided the data for the Catàleg Espeleològic de Catalunya (1978). Ramon Subirada explored it in the 90s of the last century, accompanied by a shepherd who confirmed to him that the cavity was the same one that the inhabitants of Josa de Cadí knew as Les Calderes Boteres. He also indicates to us that the location of the cavity is quite difficult.
