Description: Cave near San Esteban, visited with BUSS in 1973. Sketch survey at: OmniBUSS 5 », PDF p22.

From OmniBUSS 5 », p14 (PDF p21):

“...up a steep path, which eventually became steeper through a lot of undergrowth to a point 1 Km south west of the village where the cave, Ceuva de Los Jarres, was situated. (N.B. the walk to this cave is far worse than that to Pozo del Infierno.) The cave lived up to its expectations and is in fact the longest cave found on the expedition being in the region of 1500 ft long, with a number of passages not fully explored. The entrance is small but develops immediately into a large passage running north-south (see sketch survey.) The main passage is in the region of 10m square. The main route went on over boulders for about 100m to a large chamber where a number of ways on were noted. The main passage went on to the left in a southwest direction. After about 100m a collapsed area was encountered with a number of ways on through loose boulders. This collapsed chamber was looked at only briefly but easy digging would probably provide a way on.

The second way on from the chamber involved a climb up a narrow rift full of loose rocks. The two Mikes managed to overcome this obstacle and were regarded by finding a medium sized chamber which was fairly well decorated. Exploration continued on up a large spiral passage which ended in a 25m slope covered in flowstdne with grottoes on both sides. This section of passage being about 200m long was of similar scale to the rest of the main passage. The third way on from the chajnber led down through boulders but was not followed for more than 20m. Meanwhile Andy and Bill went back along the entrance passage to examine two climbs which went off to the east of the main passage. The easiest of these was ascended and an inclined bedding plane passage followed for 30m. At the end a pitch was located. This would seem to be the top of the other climb. The whole of this, series was richly decorated especially one bedding chamber, which was full of straws.

The accompanying rough survey was made using a compass and pacing, but no photographs were taken. On exiting from the cave we noted its position in relation to the village (village on map bearing of 53 degrees). The entrance of the cave lies high up on the west bank of a tributary stream. This stream seemed to have a number of sinks and possible cave entrances in the river bed but due to lack of time we were not able to have a closer look. David Lopez told us that (or at least we think he did) the water did sink in the stream. He also pointed out a place near the village where in winter a stream could be heard through cracks in the rock. To sum up this valley is one of the most interesting in the Deva gorge area.”
