   An excavated opening on the side of the hum enters the top of an 11m pitch. A surface opening to the west also connects. At the bottom of the pitch, a slither down enters a low streamway on sandstone. After 40m of stooping and crawling, the water disappears into a choked continuation on the left and the passage continues to a choke after a further 15m. Just back from here, on the right, a small inlet leads to a flatout crawl to a better decorated section that closes in.
   The cave is on the same horizon as Cueva del Mazo (site 312) and its resurgence site 368.
