   A cave, then outside of the Matienzo permission area, explored and surveyed by invitation of Juanito in 2007. A steeply sloping entrance leads to a crawl through to a ramp which requires a line and leads to the lower series. (No more description in the log book).
   The cave was first explored in the 1980's and archaeological discoveries are summarised in Ruiz Cobo Jesús and Muñoz Fernández Emilio et al, 2009 with a survey from that time.
   The entrance position was corrected (by a couple of hundred metres!) in November 2016.
   A trip in April 2019 looked at possible digs and climbs in the cave.
