   An easily missed entrance - it couldn't be found in the summer 2015 - that immediately slopes down and enlarges to a phreatic passage and a dig in the floor. A trench has been dug along one wall.
   Excavations in April 2018 were concentrated against the hading wall nearest the entrance where, a few metres down, the wall started to curve under. There may be a draught but, as one wall in the rift is mud and rock and it is the route for surface water, the dig was thought likely to slump in before shoring could occur.
   In the summer 2018, some shoring was installed and further progress was made under the wall.
   At Easter 2019, further digging took place and there were also visits by members of the Matienzo Karst Entomology Project - who found a possible Iberina mazarredoi spider, and the first psuedoscorpion reported in a Matienzo cave. This latter sighting might be a first for a Cantabrian in-cave find. Jess Eades also visited, looking for bats. In early June, some bones from the site were identified by palaeontologist Pedro CastaƱos as red deer. A bear tooth was found in the summer 2019. Spanish experts Pedro CastaƱos (large mammals) and Xabier Murelaga (small mammals) dug out more bones on the top level, identifying bison or auroch.
   In the summer 2019, further digging took place at the bottom and also up off the bottom, where a tight, standup "chamber" was entered through a sandy dig. Prospects at this level look poor so the plan is to continue digging below.

   The site has been excavated by Spanish archaeologists and has some prehistoric significance. A large number of butchered bones have been studied but no flints have been found. The site is classified as an occasional palaeolithic habitat (Ruiz Cobo Jesús et al, 2008).
