A short cave ends at a boulder slope into deep water. The sump has been dived to a rift with a sideways swim down into a half moon passage descending at 30 degrees. At a depth of 35m a lip is met and the passage plummets.
During Whit 95, Rupert Skorupka descended 25m down the shaft, in clear visibility to about sea level. The shaft was continuing down at another 20m with no sign of the bottom.
In October 1995, an attempt using helium in larger bottles was thwarted at the constriction.
At Whit 1996, Rupert returned and descended to - 74m, about 20m below sea
level, stopping just below a large, precariously balanced flake. The shaft
could be seen to continue down, narrow and very spiky with no bottom in sight.

In June 2003, further work was carried out by Rupert. A definite floor was reached at -81m on a slope of silty boulders. Continuing downwards led into a gallery of modest proportions with a snaggy boulder floor. About 20m of line was laid to -83m due to difficulties of manoevring with side mounted 20l cylinders in poor visability. The cave is definitely continuing downwards.
A video shows that the Grupo de Exploraciones Subterraneas de Estepona have been working here (in sifones próximos to a depth of -15m) and at Nacimiento del Río Clarín (115).
