The information below has been roughly translated from the French, Spéléo-Club Dijon reference, Simonnot G, 2016.

At the bottom of a sinkhole that takes the stream coming from las Fuentes (sites SCD2018 / MCP1756, SCD2019 / MCP1757, SCD2020 / MCP3270). (April 1987) in El Regatón valley.
It was excavated in October 2006 where progress stopped after three meters on a squeeze overlooking a sloping ledge of two or three meters. There is no obvious airflow except in winter when an outward air current was observed (February 2010) together with a sound of water at the bottom. In low water conditions water disappears a few meters upstream from the cavity through an impenetrable slot.
