A 15m overhanging cliff with a draughting slope of boulders. Digging has been abandoned as being too dangerous. A draughting rift is also present on the right hand side of the cliff.
Actividades Regionales. Exploraciones en Cantabria (anon., 1993a) has a survey of 749 which it calls Cueva Humo 2 (site 32) which has no boulders and a sink showing at the base. The position is also suspect.
