   Three possible entrances into Cueva Carcavueso. The site was explored in October 2013 beyond a tight section near one entrance. A number of strongly draughting digs were noted, and an upper entrance connected. This cave is close to the Carcavueso entrance and is believed to be that used in the past as an alternate entrance. The top of the pitch down into the main cave was cleared of a sandstone block at Easter 2014.
