   The largest entrance on this hillside. The first passage slopes down to a chamber, where straight ahead boulders have run in from above. On the right there is a slope into a low crawl. The main passage is on the left and contains some high avens. A look in on New Years Day 2019 concluded that it "seems to have little prospect".
   In 2000, some prehistoric pottery pieces, wall and rim sherds of a large urn, were found on the boulders on the right. Charcoal was stuck to the inner face. Ruiz Cobo Jesús and Smith Peter et al, 2001 puts these in context and Smith P, Corrin J and Ruiz Cobo J, 2008 compares this pottery with the assemblage in site 2139. Ruiz Cobo Jesús and Muñoz Fernández Emilio et al, 2009 compares this "Orza" type pottery to others in the Asón region.
