This site has been found, opened up, explored and surveyed by ADEMCO in April 2011. Marked AD-6.
Possibly best approached from the stream bed going up past Torca del Rayo de Sol. The stream splits and on the left bank of the left hand valley (looking up) is an area of prominences. Just beyond is a doline on the uphill left and the small, triangular entrance. A narrow, steeply descending passage enlarges. Water enters and sinks in the cave. The best hope for extension appears to be an impenetrable wet crawl with a strong draught.
This was investigated at Easter 2013 when there was no apparent draught and the very low crawl was seen to be totally flooded with a lot of washed-in debris from a rubble and clay-floored aven. It would require an effort but may be worthwhile.
