The large 15m x 8m entrance soon diminishes to a 3m x 2m passage and then closes down in crawls. Some extension work was carried out during 1997 and remains to be completed. A suggestion was made during the Easter 2006 trip that digging below the false floor may produce results.

Black markings in the cave, including dots in a semi-circle, are described and discussed in Smith Peter, 1998b (survey), Muñoz Emilio et al, 1995 and Ruiz Cobo Jesús and Smith Peter et al, 2001. The developing Acanto web site (by the Federación de Asociaciones para la defensa del Patrimonio Cultural y Natural de Cantabria) has a section on Arte Rupestre esquemático-abstracto.

Spider and bug collecting was carried out during the Easter 2014 expedition along with temperature and humidity readings.

A drone flight towards the entrance at Easter 2019 appeared to show no other nearby entrances.
