The first description has 2 caves below a sink: site 1 is 2m long and choked; the second is a 2m crawl which turns left to a dig.

Second description. The cave lies in the true left hand bank of a valley with few other sites of speleological interest but is directly between El Cubillón and the Cueva Verde resurgence. A strongly draughting entrance is at the base of a rock face and enters a crawl leading to a chamber where daylight enters from a climbable shaft above. A continuing passage is blocked by a large limestone block. Beyond is a drop down into a chamber and continuation of the cave. This was investigated via the second shaft in April 2017. A 3m deep climb down has the passage ending after a metre or so under a third (free-climbable) shaft of 4m. The overall horizontal length is 8m.

In November, 2012, a walk from the valley went up the true right bank to find a large depression (ED50 30T 0445664 4797560 altitude 280m). Unfortunately, although it had a large rock face at the downslope side, there were no obvious ways on or digging prospects.

Site 3669 is out of the permit area, but access has been given by the Spanish group who have the permit. When a team arrived to remove the limestone block, they were "unable to find the block or the passage" and suggested that "we were at the wrong cave or it is now silted up". A team "came across" the site in October 2016.

A sink, site 4539, is 5m upstream.
