   The excavated entrance slopes as a flat out crawl down to a small chamber where a talus cone, possibly a basuerero  (under the tight, original entrance pitch) has provided interesting material. Small pieces of pot were the first items to be found. A rim and side of a pot emerging from the calcited material has been excavated and found to be quite modern, ie Roman or post-Roman. Animal bones, including cow, pig and bird with signs of fracturing were also found.

   A useful summary article is found in Ruiz Cobo Jesús and Smith Peter, 2003, pages 66-69, with a survey and a line drawing of the main vase.

   A squeeze down past stal (where more pottery has been found) leads to easy going passage up to 8m wide and 10m high with some decorated sections (1  3  4). A second, excavated squeeze with a good draught enters further easy going past holes in the floor to where the floor meets the roof and chokes. The whole passage is quite well decorated with stal gours and some mushroom shaped stal.

   Climbing in the roof leads to a small choked area with no draught.

   A dig at the entrance slope goes down 10m of sloping rubble with a draught but no obvious way on.

The cave may be associated with the holes by the side of the main road, before Cueva de Bollón. See sites 1290, 1292 and 1293.
