"After we had been abandoned by all other itinerant cavers, we walked about a bit and found a new site."

Site 4019 has developed in steeply dipping beds. From the small entrance, a steep slope down on loose rock passes an enlargement with a choked passage up a slope on the left and also an excavated draughting hole. Straight ahead, the slope continues through an excavated tight drop and slope to a sump. This has been dived by Jim Lister through a 1.5m tight duck to a body-sized tube that rises steeply. A silt screw was placed at the top of the slope before the passage dips down to a tight bend and a gravel floor, where the route enlarges.

On a subsequent trip, the draughting hole on the left after the entrance slope was opened up. A tight section leads to a traverse over a hole and then a calcite blockage. This was removed to give a tight squeeze over another hole (which leads down to the far side of the sump) to a body-sized tube rising to a climb up into larger passage. This goes left and right, choking at both ends. Many tree roots hang from the roof and evidence of animals can be seen.

The sump pool, dived to the east, lies about 30m east of the inlet stream in Cueva del Embalse (and possibly at about the same altitude?)
