Updated 9th January 2018

   This site lies off the road below Cruz Usaño on the 335m contour. Rock removal and capping allows entry down 5m into a 1.8 x 0.7m "chamber". There is the possiblity of further progress with capping along a visible, narrow passage. The passage seems to draught out and needs a small, keen volunteer.
