   A 70m swim leads to a sump of 3m. A short squeeze over a silt bank to the left leads to a T junction. Downstream to the left is walking / swimming in an out-of-depth canal for 30m to a choke near to the surface. Upstream ends after 15m at a second sump which gets too low after 3m. By continuing straight on in the 3m sump an arch is met an progress continues underwater to a large choked area which blocks the passage. The site was completely re-explored and extended by Simon Cornhill in the summer 2012. The 1977 and 2012 sketches show what was done on each visit. Note that north is towards the bottom of each sketch with the pdf survey showing north up the page.

This could be a flood rising for Los Boyones (117) (quite likely as the passages have lots of silt) but could also be a resurgence for an unknown system.
