Explorations to be incorporated into the description below:
2012 summer : RH Passage before Swirl Chamber.
See logbook 2/8/12

The top entrance lies hidden in trees a short walk down from a rough road that sets off from the Arredondo-Alisas road. The entrance is a 15m wide gash which would have been used for shelter by people over the millennia and evidence of occupation has been found, both flints and Bronze Age pottery. The discovery, deep inside the cave, of a small, whole pot (cubilete), possibly Bronze Age, led to the re-opening, after possibly thousands of years, of the second, bottom entrance (recently (2016) numbered 4382).

The cave was first extended from the top entrance in 1989 by the British. The cave was then pushed in subsequent years by the Tortosa group for another 3km to about 12km. In 1994, after the downstream boulder choke was passed the previous year, some 7km of new cave was entered in joint trips with the Spaniards. The length includes 3.5km of Tortosa finds in the early 90's which have been mainly resurveyed and included.

The top entrance was used to test Ron Taylor's SubPhone in August 2016. A small loop aerial proved to be both easy to use and to give excellent communication results.

Fifty metres into the 5m high cave the floor slopes down to a flat mud floor halting straightforward progress at the limit of daylight. A draughting, excavated passage leads off from the back wall. A flat-out squeeze (that may need bailing in wet weather) and a short crawl lead to the top of a 10m pitch onto a steep slope down to a cracked mud floor and white calcite flow. Where the passage turns to head east, there is a tall, blind aven on the left. The passage continues, 10m wide and high, past some decaying antlers, to a 4m climb down. The route becomes larger over boulders and finally slopes down in a 20m wide and 25m high chamber, choked at the far end at floor level. The right hand wall consists of sand and boulders and a 23m climb up leads to a walk along the right hand wall to a large roof tunnel and a fine, bouldery veranda looking back down into the chamber. This point is close (20m) to site 1823.

The tunnel continues as the Sunday Stomps for 250m passing some crystal pools at the Glitter Run and emerging into a chamber where the ways split. To the south, the route skirts a pit and leads to a muddy 25m pitch on a corner which was the original route to the lower levels. The passage turns to the east and becomes the superb, sandy Chunnel, 10m high and wide. After 70m the floor rises to a wide, choked 15m deep pitch to the right while straight ahead the route lowers to a short climb down through boulders to a 30m pitch with a small, unexplored passage at the bottom. Just before this pitch a climb leads into a large chamber where the draught is lost.
A crawl at the start of the Chunnel leads to a drop into a chamber with no way out.

The usual route down into the middle of the cave lies near the Glitter Run. The left hand passage at the split slopes down to the head of the second pitch. Various bolt routes in avens all close down. The spacious second pitch is split into drops of 12m and 18m and lands on boulders which slope to the head of a 12m drop, passing under the 25m drop first used to enter this series. At the base of the 12m drop, a small set of passages have been pushed to chossy chokes and a strongly draughting choke after a climb down in a rift. The main route continues as walking or stooping for 150m, following an inward draught and finishes at a steep, sandy slope down into a tall chamber with a possible bolt route to a passage in the roof. Before the sandy slope a passage on the right leads to some chambers and passages with a climb down on the left dropping into B-flat Passage which leads to the base of the 3rd pitch. On the left, near the top of the sandy slope are some passages with nice gypsum formations.

A climb up of 3m on the right hand wall immediately leads to the head of the third, 13m pitch. There is a bolted climb to a choked passage above this pitch. At the base, the routes split: a slot leads directly to the remainder of the cave and will be described later; the wider route leads to the bottom entrance.

A slope and climb down of 4m passes Windy Corner and becomes wider at calcite. The passage continues in varied, comparatively small but easy going, past a number of openings, until a bouldery area is reached. It was at this point in the original explorations that a small clay beaker was found. A crawl and squeeze up over breakdown enters the bottom of an excavated 3m climb to reach the surface at Lost Pot Entrance (site 4382) behind a large, slumped section of hill side, about 100m lower than the altitude of the top entrance. The above paragraph needs amplifying to bring in the Easter and summer extensions between the 13m pitch and the bottom entrance.

The main route continues from the base of the third pitch, following a draught through a slot beneath the ladder. A maze area is entered where perhaps not all the passages have been surveyed or even explored. One route to the west, first entered in 1996, leads into The Shopping Trip, which needs describing. To the north, the maze holds the preferred route to the Corkscrew climb, described later and ends at avens in a 10m wide, boulder-floored chamber. At the beginning of this chamber, a short climb through a horizontal slot to the west, below a wet inlet, enters a small room with a high rift. An unprotected climb up gives access at two levels to the top of a deep pitch which sounds large at the bottom. There are however no obvious points for rigging and no sound rock for bolts. Further into the chamber a climb down through boulders looks down into a narrow passage heading back towards the high rift. The main way on lies to the east, where similar passages in the maze lead south to the large, calcite and boulder-floored Who Knows? chamber. Other routes also connect Who Knows? with the maze at the 13m pitch and the whole area needs describing. At the eastern side of the Maze area, heading to the northeast through Road to Nowhere passage leads to a squeeze in sharp rock. A caver coming from the top entrance might now have to put on an oversuit. (Passages in the roof of Road to Nowhere were surveyed for about 100m at Easter 96). The route then enlarges to The Canyon.

Through Barney Rubble's Uranium Mine to Galeria de Germán
In the Maze area, the first or fifth junctions on the left both lead through complex areas of rifts and crawls into an area first explored by the Catalans in about 1990-1991 and named by them L'Empedrat. This was extended in 2003-2004. The two routes enter a passage about 5m square in highly shattered rock, Shatter Passage. After a corner a chamber containing rock pillars is passed. In this chamber, draughting sandy rifts and crawls on the right are not fully explored, and to the left a small passage, Centipede Crawl, joins the main route further on. The main route continues after the chamber with odd sections of crawling. About 100m beyond the chamber, small holes on the left lead a complex area with three routes leading off. To the left is Tits Up, next, through a tight rift is Barney Rubble's Uranium Mine, while to the right rejoins the main route at a 2m climb down, mentioned below.
The main passage of L'Empedrat continues to a larger section where the 2m climb comes in on the left. The way on is a climb up into a roof passage. 50m further on a slope up and drop back down is soon followed by a final chamber with a draughting choke. A climb down on the left leads to a decorated passage loops back, crossing a blind pitch in the floor.
Tits Up leads to a choke dug through at Easter 2004. Beyond, a passage passes a draughting passage on the left, continuing small and heading towards Pillar Chamber. Beyond is a 4m climb up into a wider passage, crossing a short pitch and ending at a long-term dig after 76m.
Barney Rubble's Uranium Mine
was entered at Easter 2004. It is about 250m long, largely crawling over sharp rock, with a tight section at the start, and dug out in places following a fair draught. At the end larger, unstable, passage is entered, choking after 7m to the right, and to the left reaching a choke after 17m beyond. This was passed in the summer of 2004 on the right, entering a large chamber with pitches in the floor and left hand wall (explored down a handline to a very tiny outlet at the bottom in 2005). A 40m handline is recommended for descent into and traverse round the first part of the chamber.
At the far end of the chamber, the continuation is followed for 170m with a pit traversed round on the left, and is followed by two 20m pitches which have been descended. The first is reached by a steep slope down on the right, and drops to a low passage blocked by a boulder one way and pushed to an aven the other way. The second pitch is just beyond the first, in a slot with a short vertical descent to boulders with an aven to the right, then a steep slope down to a passage ending at avens and a 10m pitch to a short bit of passage. At the bottom of the pitch/slope is an unexplored passage over a pit on the left. A few metres beyond the two pitches, the main passage ends at The Bridge of Khazad- Doom, overlooking a large passage, Galeria de Germán. This cannot be reached directly as it is cut through by a big hole taken by the second 20m pitch. It is reached by crossing The Bridge of Khazad- Doom, followed by a 15m rope traverse, The Traverse of the Pigs, and a 5m pitch down. The passage is followed to an aven where a passage on the left reaches a larger passage, ending at undescended shafts to the left and a chamber to the right. Galeria de Germán continues along steep mud slopes requiring traverse lines, and has been explored as far as a 6m handline climb to a lower level. This has been explored as far as an aven chamber.
In October 2004 the far reaches of Galeria de Germán were extended. The slimey climb at the end has blocks held in by glutinous clay and reaches a bouldery chamber. Holes on the right connect to a parallel chamber; a hole on the left leads to a canyon stream and a 9m pitch and aven. Straight on from the climb reaches a stream trench and to the left leads to a meandering passage with white sand banks - Dark Angel Desert that chokes after a small chamber. Back on the left, there is a 10m undescended pitch.
To the right at the stream trench, descorated passage is reached - Mollusc Magic - and a passage that parallels the route in. A pitch at the end drops into muddy narrow rifts with possible crawls to be pushed.
The pitch marked "?p15" at the traverse and turned out to be 19m deep.
In the summer of 2005 most leads were pushed to a conclusion - the results are very "bitty" and have yet to be tied in with the descriptions above. The notes from the log book follow:
Pitch at the end of the stream trench, 30ft into small chamber with body-sized crawl leading to an impassable meander.
Body-sized tube on left at end of dry passage led to continuation of passage (low bedding) becoming too low over calcite floor.
Slope up a side rift at start of Mollusc Magic went to more small passage, slippy climbs up at end of M.M. also went nowhere.
Everything else went nowhere - bottom of Sala German; bottom of pit in first chamber.
The remaining leads are a passage on the left at the base of the pitch by the Bridge of Khazad Doom; tight rifts in the first chamber.

... and should be compared with notes from Patrick Warren:

All leads to W of the rope climb at end of Galeria de German were pushed to conclusions.
To S of Dark Angel Desert, two crawls are accessible and open out on opposite sides of a ~ 3m climb, with a further ~ 4m drop to the base where there is an impassable outlet (a rope is essential to return up the last ~ 4m drop).
Underneath Dark Angel Desert, a vadose trench can be followed to a ~ 10m pitch, descendable (just) as a rope climb. From the bottom, ~ 10m of sideways thrutching in the base of a narrow rift leads to a point where it is possible to turn around. Beyond here, violent meanders in the body-sized canyon passage halted progress. Thus far, the streamway appears to be following below the line of the main passage.
N of Dark Angel Desert, a passage leading W becomes definitively too low beyond a tight tube. N again (Mollusc Magic), the muddy climbs were explored to conclusions. To E, there is a tall rift partly filled with large fallen muddy blocks, but no way on was found.
In summary, apart from the vadose canyon trench below the 10m pitch which a very determined small caver might push, there are no remaining leads in this part of the cave.
The first pit encountered on entering the extensions after leaving Barney Rubble was descended as a rope climb. This is the one before the *original* 'bridge' of Khazad-dum. It was ~ 12m deep - the first 6m on a suprisingly stable boulder slope, and the last 6m vertical. An impenetrable fissure was the only passage leading off the base. It's worth noting that this means the pit is apparently unconnected with Pringle's black space visible through gaps in the main passage wall at the top and far side of this pit.

The whole series was detackled after the "final" exploration.
A scan of the 2005 notes on the Galería de Germán survey is found here.

In 2006, further passages previously explored by the Catalans were surveyed. This series, the Man Trap, is parallel to the Galería de Germán and extends westwards for some 800m. (Proper description required).

To the right of the Maze Area, and before the Hole in the Wall, on the right of the passage is a 12m pitch, descended in 1996, down to a short passage into the narrow Haymarket Stream Passage. During easter 2003, a pitch in the Haymarket Series was descended for 8m to a tight mud tube and a too tight rift. A boulder choke above was looked at with a possible tight climb up in blocks. At Easter 1998 another pitch was explored in the Maze Area with the Catalans, but was unsurveyed.

Passage opposite Hole in Wall was explored in 2003 for about 30m to a choke and an aven.

Going through the Hole in the Wall leads to a steep slope down and pitch up to a mud traverse to a low chamber with the way on in the right hand corner. This route is not recommended and the corkscrew climb should be approached via the first major easterly junction in the previous maze area. A small tunnel with a calcite floor follows the draught to a 6m corkscrew climb or easy 10m pitch. A tight squeeze leads to a split level route, in the water or above, following the draught. After passing an oxbow on the right a junction is met and a climb down. Downstream, another junction is soon met: downstream, the passage develops a trench in the floor of a wider passage, but eventually becomes low. A low duck leads to 50m of wet crawling to a possible sump, while a short inlet becomes too tight; upstream the passage joins The Canyon. A high level, narrow traverse leads to an aven. Above the aven is 50m of passage, blocked by stal. The floor rises to meet the traverse and easy walking pops out into the base of The Canyon.

At the junction climb-down, the upstream route enters a narrow passage with pools. After some 250m, where the passage trends east and passes under Who Knows? chamber, a shelf above the stream is followed, passing inlets of the left and right. An inlet on the right is a muddy crawl which leads to a gradually enlarging passage, not pushed to any conclusion. After a corner two further avens are passed and a stal constriction is reached. A 10m flat out tube leads to the bottom of a very loose climb through boulders in a narrow rift. A 30m by 10m chamber is reached and the left hand wall followed to drop down in an awkward climb to a spot where two passages have not been looked at. A shuffling passage widens to walking and a large, low chamber to the east which has not been pushed. (There are also other possibilities for pushing in this area). The route on follows the draught in the roof to a 44m long chamber, only 2m high with an "egg shell" floor. In the far corner is a tight squeeze and contortions into a passage which climbs up through a bouldery floor. On the right is an easy crawl which has yet to be pushed. Following the draught from the chamber leads directly to the Lost Pot Entrance.

At Who Knows chamber, the ramp on the right has been climbed up through boulders to about 60m of well decorated passage with several draughting avens in a passage called Where Who Knows Goes. In this vicinity Walrus Passage is a side passage linking to the main route in three places, partly surveyed, and which also links up ramp to passage to Who Knows.

At The Canyon, cut by a stream crossing the passage at right angles a tight and sharp climb down leads to a step over a short drop to the stream. A Tyrolean was installed over The Canyon in July 2016 to help transport diving equipment across the drop. A muddy climb up on the opposite side reaches the continuation of the passage. The passage is again of reasonable size, walking with the occasional squeeze. After 80m the way splits, the northern route passes an undescended pit and then narrows to emerge in a 10m wide passage. The eastern route, the Clapham Bypass is easier going but emerges in the same passage at a group of pleasant formations. Routes at the top of the decorated slope were pushed and partly resurveyed at Easter 2008. In the summer, it was noted that a draughting aven on the east side of The Canyon need some protection on a climb up to passage.

Also during Easter 2008, in the Clapham Bypass vacinity, Smelly Hat Aven yielded 275m of passage and it would appear to be very close to the base of site 753, Torca de Rotura where a sandy floored chamber has a 10cm wide fissure emitting a cold draught. In August 2017, a subphone test was carried out here - with faint voice contact, but comminications had to be abandoned after the surface team was caught in heavy rain.
In the summer 2008, "to the right of the Easter climb in Graveyard Chamber", a rift was bolted which led to rifts in the roof of the chamber. A 3-bolt climb to the northwest in the same chamber didn't look to be heading into passage.

An aven just after The Canyon was dug through stal in 2003 to an aven and muddy, draughting inlets that became too tight.

Chambers to the south of the Clapham Bypass - Road to Glory  junction were pushed in 2003 through stal into a chamber with a dig through stal into a further chamber with a good draught.

The passage to the north of the Clapham Bypass continues up to 15m wide and 10m high in the sandy-floored Roads to Glory. On the right of this passage a slope leads to 5m and 6m pitches to immature streamways, which may have been descended. To the north, the passage splits, the right hand branch lowers to a crawl and finishes in a low, bouldery chamber where voice contact can be made with explorers in the bigger passage beyond. (The chamber was surveyed in 2008 - batch 197 - and currently heads south, ending in a continuing low crawl.) The walking-sized left hand branch passes the entry point to Galeria Jesús Lecue and gradually enlarges to an impressive junction after some 60m.
Galeria Jesús Lecue
(surveyed as batch 0733-17-01, length 86m) starts at the top of a sandy slope and becomes smaller to a crawl then varied going to a climb over an undescended 8m drop and, a few metres beyond, another uindescended drop of 5m. A squeeze at the top of a small slope reaches the end where a small inlet enters. The drops require further investigation.

Back at the impressive junction, to the right the route becomes 20m wide and meets a boulder slope with a crawl at floor level under boulders to a dig. Above, the slope rises to the east to a large, draughting boulder choke, which was declared a major project at Easter 2001. A northern branch slopes down to a 12m climb up, where a ladder is needed. The passage (La Pita) leads after some 50m to an undescended pitch (above the avens in the lower stream passage). After another fifty metres at high level, a passage sets off on the left to a climb and choke, surveyed in 2003.
An attempt at Easter 2012 to reach La Pita was put off as "the rope climb looked 'iffy' and we didn't think it was SRT".
The "passage running north of Bathtub Passage" (presumably Pita Passage) was visited in the summer 2013. An "horrific" aven was climbed, covered in 2-inch thick mud. It was also reported that the team had "pushed through the northern boulder choke" and dropped a 15m pitch in a water worn shaft with a hideous mud walled outlet. Across the top, a route through "boulders and loose stuff" was pushed to a small aven and a "hideous and mud walled immature inlet". (There is no survey of this section.)
The choke (at the end of Bathtub Passage) was inspected at Easter 2013. One account says "apparently dug into possible continuing passage." Another account states, "This would be a long term project", although whether this refers to the old or "continuing passage" is unclear.

To the left the passage (Avinguida de la Sorra) has a superb flat roof and sandy floor. Pits at the start were investigated 11/8/17 as a free climb down into a narrow streamway. This was followed around several bends until it became too tight. The Avinguda enters Swirl Chamber at the base of a large boulder slope. Swirl Chamber is approximately 40m in diameter and rises up on loose boulders to three passages at the western side. The northern tunnel ends at a choke after 50m, the middle line continues uned after 50m and the southern one continues for 120m to an unexplored pitch. On the southern edge of Swirl Chamber, a small passage enters an unsurveyed section containing a large, undescended pitch and a route heads back to link with the flat roofed tunnel, joining it half way along.

The Climb on the Big Junction Series was entered at Easter 2001 by climbing up a steep slope to reach a climb down into the base of a drippy aven. The inlet involves loose climbs, low crawls, and short walking rifts into an aven series. Climbing up 8m leads to another short length of cave ending at avens with choked rifts leading out.

The only route through to the rest of the cave lies to the north at the base of the boulders cascading out of Swirl Chamber. A short walk over boulders emerges at the five way FN Junction. The large boulder slope to the left chokes. Six Hundred Pesetas Passage is entered on the opposite side of the junction. This passes crawls on the right after 20m and passes a 30m pitch (apparently explored by the Catalans) where it turns to the west. Two side passages on the north side were looked at in the summer of 1999. The first crawl on the right after the pitch leads to a junction after some 50m. The next junction enters a small passage that ended at a 22m pitch that was too tight at the base.

In 2011, the strongly draughting choke at the end of the passage to the right before Swirl Chamber was investigated. The Catalans had banged this the previous November and it looks "very dodgy". A roof passage was also noted near the choke and needs a traverse bolting.

Also in 2011, a climb in the roof over The Dragon in the Maze area went 10m to a narrow rift.

Albert's Grand Passage and beyond
During the summer 2002, a climb of 40m up and around a calcited wall in FN Passage enters Albert's Grand Passage and Skyhook Passage. This continues (bolted in November 2002) beyond a deep pitch which has been explored and closes in. (Description of the series required). In 2003, a bolt route around the pitch was tackled into the draughting, continuing passage to a T-junction and holes down.
This was pushed and surveyed as Broken Tooth Passage at Easter 2004. On the far right side of the aven, a small window can be entered. Climbing down leads to several blind pits with stream dribbling above. Squeezing to left yields a window to another aven pitch 10-15m (not descended) Water/(stream) can be heard at bottom, probably that dripping in.
Crossing the main pitch leads to small muddy passage (to the left of that described above). After a short flat out crawl, easier progress is made with some good decoration. A small break down chamber is reached. Continuing on, a very well decorated chamber is reached. Left leads to a wide section of passage, but blocked by calcite flow at the end. A passage on the left leads back to the breakdown chamber. All other passages/climbs on the left are blind.
On the right hand wall a very tight rift (needs hiltiing) drops to a floor 3m down with possible passage. No other leads. To the right leads to a 6m pitch. Over the top of the pitch, climbing up the calcite flow, a possible chamber/aven can be seen through calcite, possibly draughting. This would require some work to remove calcite.
From the base of the pitch, several holes and a chamber 4m off floor to the right, are all blind. Asending the muddy slope leads to a collapse. A passage at the base of the collapse, to the left leads under the collapse with stream dribbling in from it - blind, no draught. Climbing the collapse yields a break down chamber with several short passages, all blocked. Draught does head through this collapse area.
Leads:
1 - Swing into window to undescended 2nd aven. Possible rift heading off, but hard to tell. Not believed that base of 2nd aven deeper than 1st aven. Water flows out into 1st aven directly below swing in window. Probably same water as in 2nd aven.
2 - Possible aven over 6m pitch, but difficult to tell. A lot of work to gain access, but may yield by pass to collapse.
3 - Tight rift in large passage. Needs hiltiing - Not thought worthwhile

Six Hundred Pesetas Passage becomes floored with calcite and then sand, and ends after 350m from FN Junction at a boulder choke. Just to the south of Six Hundred Pesetas Passage lies the entry to a small tunnel which passes a 4m drop after 50m and leads to the 9m deep Tuesday Pitch. At the pitch base a small passage continues low and nasty upstream while downstream it leads after 100m to the Rioja River. This is also entered via Dutch Pitch, described later.

The FN Passage to the east of FN Junction is 20m wide and 10m high but appears to be just a small segment of a longer passage as it lowers and closes down after only 150m. There is an unexplored pitch and dig at the end of this passage. On the left hand side of FN Passage, after it has turned north, the Catalan Climbs series starts. A c34 up reaches further slopes up and a narrow vadose passage. A climb up mud and boulders has not been attempted.

Further along FN Passage, November Passage leads off on the right. This rises to Amazing Stal Chamber with good formations and calcite runs, choking after 125m.

Where FN Passage swings north, two exits lead off on the right wall. One is entered via a slope down and after some 60m this route ends at a boulder choke, an unsurveyed chamber and an undescended pitch. The higher passages lie at the top of a climb up the left hand wall and across a blind pit. The right hand route leads to The Dutch Circle where a loop contains formations, boulders and a 20m undescended pitch. The left hand route (in a small vertical maze) leads to a 4m pitch followed by the 31m deep Double Dutch Pitch, the normal entry point to the lower streamways.

At the base of the pitch, a small muddy streamway is met. The upstream route ends at an aven after 150m, while downstream the small passage becomes a 4-way junction at the Rioja River. A tiny inlet (Shit Inlet) was entered at Easter 2002 and goes for 25m. The main passage upstream sumps after some 120m, after passing an inlet on the left which enters boulders where a link to the main stream goes off to the right. A trip in 2015 discovered passages off the dry section in the Rio Rioja that, apparently, go off in all directions. A sketch can be found in the summer 2015 logbook, dated 9/8/2015. These passages were further investigated at Easter 2016 and surveyed as batch 0733-16-01 (143m new). See logbook 28/3/2016.

A trip was made in August 2016 to the avens at the upstream end of Rioja Reserva to check prospects for work the following year. The aven was climbed in August 2017 but it had already been bolted. The aven closes in at the top. (Video)

Upstream sumps
   The upstream sump was dived in August 1996 by Rupert Skorupka. Sump 1 (Lady Beatrice's Underwater Fantasy) was delightfully clean and surfaced after 21m into more streamway. Within 40m sump 2a was reached and passed after 47m. This sump had underwater flowers of calcite on the walls, and a skin of calcite on the surface that was duly smashed from below. 176m of pleasant streamway was then explored to sump 3, another inviting, unexplored dip. During the wet and cold Easter of '98, pushing the sump was continued by Ross Greenwood and Martyn Holroyd. Sump 3 was dived to small chamber at -2m with the way on being down a gravel slope into a comfortable sized continuation. The sump continues NNE, dropping to -6m then rising steadily up a large silt bank, then again dropping to -6m. After 50m, the main tunnel appears to rise up a rift with a parallel rift also rising to -1m without surfacing.
   During the same trip, a passage was noticed on the northern side of sump 2a and this was followed in large passage along doglegs, but generally heading north. This was obviously the main route on and exploration stopped at the end of the line at -6m and 50m in. Exploration continued during Easter 2000 when the sump was extended by 100m and 130m over 2 trips. About 280m from base, the passage surfaces in a narrow, miserable canal for some 10m. The passage then sumps again and was pushed at Easter 2001 for another 200m mainly through rifts and over silt banks and still heading NNW. The way on continues in similar fashion. (A survey of the sumps from 2001 is found here).
    In the summer 2016, Jim Lister dived in the main upstream Rio Rioja sumps. They needed some re-lining and tidying up and about 70m of new flooded passage was pushed to a point (a slope down with a hole visible) where larger cylinders and logistics were needed to progress further. On August 5th, 2017 an efficient team carried in many bags of equipment for the dive. (Video). Unfortunately, this northwest route (sump 2B) was found to choke (6th August 2017) almost immediately with gravel when Ashley Hiscock dived. There is some doubt about the accuracy of the old survey as Jim's line was laid for 570m before Ash continued a short distance to the gravel blockage.

Vallina 3
   The day after, dive equipment was transferred to the eastern route where sump 3 was pushed "directly behind and above in the diver's blind spot" and passed to an active stream. The first entry into Vallina 3 has been surveyed as batch 17-02 (length 403m; Jim Lister with Mark "Killer" Smith). A video of the explorations is found on YouTube.
   The stream is followed for 30 meters to sumps 4 and 5, both of which were relatively short. On surfacing beyond sump 5, in a foam-covered sump pool, a reasonable sized streamway is encountered with a junction a short distance from the sump pool. The passage heading east ends in another sump (sump 6) after a short 5 minute walk.
The left hand side passage heading north meets another substantial steam entering from the left. Although this streamway appears slightly smaller it emits a substantial amount of crystal clear water. 
    The main stream passage can be followed to a boulder ramp that enters a sizable breakdown chamber with the stream continuing on the other side. The streamway (4m wide) with muddy banks and white moon milk/calcite bed consists of partly crawling and partly walking passage. The streamway opens up into a boulder strewn inclining passageway (20+ degrees incline). A passage on the right hand side (going in) has been noted but has not been explored.
   A further climb up a ramp with boulders leads to an apparent choke. The way on is found on the right hand side with a climb up through boulders into floor of a sizeable chamber (30m x 30m approx). The stream can be heard on the far left. The boulder ramp up to the far end of chamber and a window has been noted and explored on right hand side up about 7m. This has been climbed to reveal a large, well decorated chamber of similar proportions (30m x 30m) with some nice formations. Above the climb, a possible aven with flowstone has been noted.
    Back in the initial chamber the left hand side has been followed up a 20 degree slope to a small climb down back into the streamway which goes a short distance where it divides into three. The middle route, with the least water, ends in an impenetrable calcite fissure. The other two streamways have not been investigated.
   At the first breakdown following sump 5, taking the left hand, north passage directly after sump surface, the streamway (1m wide x 3m high) can be followed, passing an inlet on the left hand side carrying a decent stream. This has been left uninvestigated.

Downstream
The easy downstream Rioja River passage continues for about 700m. The passage starts with standing water and after 250m meets the inlet from the Tuesday Pitch. The water then heads off to the north along the small Where the Rioja Goes, unsurveyed to a sump. A dry continuation of the passage gets larger to the west and after 50m meets another stream flowing from the south - the Rioja Reserva. This stream passage is of impressive dimensions for most of its 400m length. It ends where the water wells up through a choked area. A short crawl to the north enters a number of avens.

In 2009, an aven and tube seen from the streamway entering the Rio Rioja (Stream Passage) were investigated but "the aven needs serious bolting or scaling".

Downstream, the Rioja Reserva continues west to meet a sump. (The size of this stream is similar to the stream which disappears in Where the Rioja Goes, although the latter does not appear to join the Rioja Reserva streamway). The sump has a short bypass via an awkward climb up a steep tube where a rope is useful and the stream passage continues and enlarges for another 100m to end, after a complex boulder area, with a sump and small inlet passage. The water (in dry weather flow) has been dye tested but detectors in Cueva Molino (791) at an altitude of 200m and Cueva del Comellantes (040) with an entrance altitude of 170m proved negative after 2 weeks.
   According to Guy Simonnot (pers. comm. October 2011) it is likely that the flow in Molino (site 727) can be accounted for by Orcones and "the collector - Cantu Pasillo Encarmado." He continues, paraphrased, for cavities such as Vallina we may need to think about another source (resurgence) - which would suit me better geologically."
   The downstream water was traced to Reñada and Comellantes (site 0040) at Easter 2015, see below.

A significant extension was made above the sumps in October 2015. Batches 0733-15-02, 03 & 04; length 716m. The following description is by Peter Eagan.
   In the short sump bypass passage, about 100m upstream from the main downstream sumps and the connection to Vallina II, a climb up on the left enters the Catalan Oxbow. This is about 50m of passage explored by the Catalans ca 1990?, ending at drops to the stream further upstream.
    Where the sump bypass drops back to the stream at the downstream end, a short climb up above the handline belay was pushed in 2015. At the top a short crawl enters larger passage. To the right, a wide section can be followed for about 50m above the stream. This may also be pushed further by climbing up further downstream.
    To the right, at the end of the short crawl, a passage on the right is the start of the Sisters of Perpetual Indulgence. Continuing past this passage, a drop connects to the Catalan Oxbow.


   The Sisters of Perpetual Indulgence starts as a rift passage hading to the south, generally 0.5-1m wide and 3m high, with numerous sharp flakes of rock. Side passages as far as explored are all oxbows or close down. After about 100m a narrow section is passed by climbing up to the Quaking Traverse. Beyond this a wider passage is entered at Pantaloon Junction.
   Heading left at Pantaloon Junction and then right through a constricted section, a complex area of chambers and draughting crawls is entered.
   Right at Pantaloon Junction the passage has been explored for 270m with some side passages pushed a short distance, but may also be oxbows. Passage is phreatic and formed on a series of parallel joints/faults, quite narrow in places due to eroded flakes splitting passage. Exploration stopped where passage on right ended at 8m pitch needing tackle.  Some 25m back a passage to north ends at a 4m pitch again needing tackle, note roof and sides are loose. Passages can be seen across top of both pitches.
   More exploration occurred at Easter 2016. An 8m pitch in the right hand branch quickly lead to a blind 12m pitch. At the top of the 12m pitch a traverse became too narrow. The climb down at the left hand branch was choked but a traverse on good rock on the right hand wall lead to an aven above the previous 12m pitch with a view of the top of the first (8m) pitch. The way on is easy going 2x2m passage. Peter Eagan wrote:
   "Crossing the roped traverse leads to further passage of the same style, with a passage on the right heading back towards the two choked pitches (these are currently un-surveyed). Some meters further forward leads to a mazy section that has a number of possible ways on, only the main route was surveyed.  Most of the corners have sharp continuations that go for a few meters."
   "Once you zig-zag through this section there is a fairly sudden change when the passage drops to a mud-floored, upward sloping passage.  This passes a pit on the right and becomes sand floored as you approach a cairn on the floor. This marks the first stream approach; following the passage down to the right leads to a balcony overlooking the main streamway (10.5m drop). The stream comes from the right (looking out) and curves around (probably about 20m wide at the furthest point) and probably disappears underneath the balcony.  It will be easy to ladder the drop from a bolt in the wall."

   The main passage continues wide and sandy, passing a small cluster of stal.  At the junction, the main passage continues, past a small hole through which the stream can be heard but gradually closes down to about 20cm high. “It would dig easy, like”.   It did not appear to enlarge, but it is certainly worth further investigation.
   Back at the junction there may be a way forward to the left – this was not checked.  The next passage to the left is a vocal connection down a rift that would need tackle.  The route to the stream is to almost double back in the left-hand wall and climb down a few meters to a muddy slope down to the second balcony.
The stream flows from east to west under a couple of massive boulders, supported on virtually nothing (10.5m drop to stream).  The west leg has a possible traverse which might reveal a climb down to stream level, but the rock is all very loose and it needs tackle.  There may be a way on continuing over the streamway – this was not properly checked.  Ladder down to the stream, but the hang is not as good as the first balcony.
   This area corresponds to the part of the drawn survey between sumps 5 and 6 where the possible climbs out of the stream are shown. This passage was surveyed as batch 0733-16-04, length 294m.

   Another exploration during the same period involved pushing on from station 33 south of Pantaloon Junction. A small phreatic tube ends in a too narrow drop of about 20m with the sound of a stream below. There is a strong draught out, although one explorer describe the route as, "The most hateful bit of cave I have ever been in!" (Batch 0733-16-02, length 120m). Some narrow rifts head west from station 31 and there are several mazey crawls from station 30 heading back to sump 1.

   Some pushing and surveying was carried out in the passages off Sisters of Perpetual Indulgence above sumps 5 and 6. The main leads were pushed and surveyed in October 2016. The major find (surveyed to 231m) was an intermediate level entered via a 2-ladder pitch. This dropped into a small chamber with 3 ways off (batch 0733-16-12). (Batch 16-11 repeated part of 16-12)
   One route headed north into the large (20m wide x 15m high with large mud banks) inlet passage entered by diver Martin Holroyd in 2002 and the window into sump 6 where he popped up.
   To the east leads to 3m by 4m high, level traversing passage that ends looking over the beginning of sump 6. Rupert's dive bottles were seen below but the team were 10m above the stream way and couldn’t find a safe climb down.
   The 3rd way was through Swiss cheese tubes and enters a high level passage going south in the opposite direction to the sump. This petered out but there is a high degree of certainty that further exploration lies in this direction in the inlet stream way below. The inlet stream was followed for a short way but a bit of hand line rope may be useful if continuing up stream as it involves some steep muddy banks to continue.
    Batch 16-10 continues west as a short climb down onto a muddy slope to a 10m pitch. This is apparently undescended - below looks sandy-floored and up to 5m wide. Water is heard below but only a small inlet is seen.
   One trip at Easter 2017 started bolting high in the stream passage to try to bypass sump 6. Work will continue.
In the summer 2006, the "left hand branch of Rio Rioja" was examined and had a very good draught which "seems to go up avens at the end".

   The summer of 1993 saw a joint Spanish / British trip to look at the downstream sump which was dived by Phil Papard. The dive took about 45 minutes and the diver turned round at the start of sump 3 after some 120m. There is 20m walking between sumps 1 and 2 and an airbell between sumps 2 and 3. The large chamber above sump1 was surveyed in October 2016 (length = 99m) but was not tied into a known survey point.

   At Easter 2002, Martin Holroyd extended Phil Papard's downstream dive to give 644m of surveyed passage through 5 sumps with about 500m of above water passage.    Sump 2 is soon passed into a fine passage with a choke running in on the right. The next inviting sump is an easy swim surfacing at a spike.
   Sump 4 was new this year and is a large, blue sump gently dipping down a gravel slope before gently rising to surface. Sump 5 was passed, similar to the last into open passage. A wonderful stream passage follows, up to 15m high. Two inlets and a possible climb up mud are passed, before finally turning a sharp corner and another large sump.
   This was entered on a following trip. After 60m the sump enlarges and drops off below to the right. To the left, a steep ramp rises up. This reaches air space giving a sump 6 length of 110m. The exit is up a difficult mud slope. A large, very muddy inlet can be followed upstream through massive mudbanks, evidence of substantial backing-up. The inlet becomes smaller with awkward climbs up mud slopes. The solo explorer gave up where it was necessary to crawl and squeeze at a junction. The left hand branch was draughting strongly.
   In the summer of 2003, a further 110m of line was laid downstream. The route descended to -22m and has now gradually risen to -17m where it is seen to continue.
   In the autumn 2015, Rupert Skorupka made 9 trips down to the start of the sumps, ferrying dive materials. The gear was put to good use at Easter 2016 when he started a series of dives, relaying lines through the sumps in preparation for a further push. Further work in the summer included re-lining sump 5 and moving dive gear reasy for a major push into sump 6 in the autumn 2016. The high level route (Sisters of Perpetual Indulgence) was examined as a path for the diver to a safe bivouac spot above sump 6. However, the awkward nature of the passage meant that it was not a good option, but it does provide an escape route and access for the assistance of non-divers.
   Although Rupert did some work in the cave in October 2016, one diving was carried out due to a cold.
    At Easter 2017, a start was made on re-lining sump 6 but work was curtailed by tourist trippers in the system. In the summer 2017, further re-lining was carried out and sump 6A, up to the junction with the large inlet, was resurveyed (batch 0733-17-05) - clearing up perceived errors in the SoPI-main streamway-sump 6 loop. In October, Rupert visited the cave 9 days in succession to take in a KISS rebreather together with all the necessary components. In addition, several depleted cylinders were replaced. A window of perfect weather allowed this to-and-froing to take place without any risk of gear being washed away. A full account can be seen in the Autumn 2017 Logbook.

Detailed description of the downstream sumps (Rupert Skorupka, July 2016)
   Sump 1 leads off where a short section of passage carrying the combined streams of the Rio Rioja doglegs right at the sump pool. After 10m at 2m depth a junction is met with a line off to the right. This surfaces quickly at a small, muddy sump with a stream inlet which can be found on the route through to Vallina 2. Turning left a small (2 x 1m) passage surfaces in a canal with swimming and walking to sump 2. Total length is about 50m, depth 3m. Sump 1 was originally bypassed by a muddy inlet but it is much easier to take the dive route.
   Sump 2 starts after a 20m swim where the line follows a small tube which is an oxbow for 15m to a larger tunnel. Beyond a chamber is an easy thrutch up through a massive choke, to surface after 25m in a very large tunnel. This choke was never mentioned by PP or MH and may be a more recent movement (?) of boulders. Sump depth 3m. Beyond sump 2, the passage enlarges dramatically, so I think that the Vallina 2 water enters somewhere in the choke.
   Sump 3 begins in a 10m diameter pool and a huge tunnel dips down to about 6m depth before rising to surface in a huge airbell after 25m. A small tube on the left here, at water level, has the sound of a sizeable stream in it - but this is not seen entering anywhere.
   Sump 4 follows and is again very large, over fallen slabs, to surface in a canal after 45m, depth 3m. A canal passage allows floating along to sump 5, after about 30m of sizeable tunnel.
   Sump 5 dips down to the right to a nice belay in a rock eyehole, depth 4m, then gradually rises up a massive gravel slope to emerge after 45m in an impressive river passage

A route through the boulders at the original downstream sump leads to a small passage heading west and a tight section where a strong draught encourages digging (see below).

Individuals of Nemastoma were collected in the area of the top of the first pitch.

By August 1991 the Tortosa group appear to have extended the cave to some 12km long.

Bolting was also started at the upstream end of the lower levels and this is still proceeding. (?)

The draughting boulder choke was also inspected and on a later, British-only trip (with permission), the boulders were passed through an awkward squeeze into a chamber. (In 2012, the squeeze was thought to "shifted on the right hand wall - now tighter than it used to be??". The squeeze was enlarged in August 2015 to allow "normal cavers" to pass.) A passage on the left is choked with mud and boulders after about 90m. Most of the draught in this section disappears in the roof through small holes, one of which has been followed for about 50m via very small, awkward meanders to a tight squeeze through which water can be heard. A sketch (2012) of the route through into "Vallina 2" is shown here.

Beyond the chamber a stream is entered; upstream and crawling over boulders on the right leads to a large chamber (end of '93 extension). The main extensions occurred during 1994, with additions during 1995.

A low, muddy passage leads to a climb down over boulders into a main stream passage, the Rio Grande, explored upstream for about 1.6km, (Pictures 1  2  3 4 ) mainly in fine, large passage. After 300m, an inlet on the right, Río Blanco, has been surveyed for over 1km, mostly walking-size, passing a 20m diameter aven chamber, the Novadome (disto'd in 2012 to about 48m, probably halfway up). Several leads remain. At the end, Muddy Waters, a duck was passed in 2012 into chest deep water. Cross rifts lead to the only feasible way on - a too tight hole where the floor rises and water slops over the edge. Also at the end of the Rio Blanco (up climbs and narrow rifts) a flowstone squeeze has been passed to a short length of passage ending at a 3m high narrow rift.

Just before a canal section in the main stream, some 300m further upstream, Waterfall Inlet has been explored up an awkward 4m cascade climb followed by a 12m wet bolt climb in an active aven after 120m. At the top is dry passage and a continuing upstream passage to twin avens, one taking the stream. The Passage That Turned to Jelly leads off on the left to enter the Novadome, 20m up.

The next inlet, Simeon's Loop, has been explored to a climb up into a higher level fossil passage. Left leads to a continuation to the cascades in the main stream and a connection back to the inlet passage. On the right (Not Simeon's Loop) is a fossil passage, passing a bolt climb to possible higher passage, not yet completed, and eventually invaded by the inlet, ending in a waterfall chamber with the stream beyond coming from an aven of about 10m, not climbed. At the chamber, a steep climb over mud formations enters large fossil passage. To the right a route involving awkward climbs of 6, 5 and 6m connects to Rio Blanco upstream of the Novadome; to the left passes a pit then well decorated bouldery passage, ending at a huge pit. the First Abyss, above Thornton Force. A traverse to the right reaches the continuation of the main fossil passage, the Galeria de los Elefantes, and a route left leads to a view point above Thornton Force.

In 2003, an unsurveyed passage running south from the west side of the First Abyss was entered. This is 4-6m wide, 1 - 4m high and very well decorated, ending at a diggable choke with a small draught and some skeletons.

Back in the main streamway, a boulder choke is passed, then Quicksand Passage on the left - entered for 20m and draughting. Beyond are climbable cascades below the connection to the previous inlet. A large chamber follows with a 5m pitch up beside the water (Thornton Force). This was left rigged in 1993 but by 2003 the rope had been destroyed by floods. In 2006, the pitch was left rigged for a pull-through descent requiring an 18m rope.

Above the pitch, a number of slippery cascades need a rope or combined tactics in Kingsdale Passage. After some 120m, an inlet on the south side was pushed for 119m in 2006. Exploration was left when the way on divided: a return visit is required. After 400m upstream, a roof passage enters a high level series of large, very well decorated passages, explored for 1.3km. The first section, Crystal River Passage, leads to a huge pit, the First Abyss, where a 30m climb down reaches the floor. A descent over and between boulders, beneath a large boulder leads to a slot which may provide a pitch down into Thornton Force chamber. A slippery, exposed climb up the opposite wall leads to continuing large passage, the Galeria de los Elefantes, explored to the Second Abyss.

Several side passages lead off on the right of Galeria de los Elefantes. First is Frog Passage, mostly crawling, which ends at the twin avens reached from Waterfall Inlet. Part way along is a frog (?) skeleton. Next are two passages which join and reach a complex area explored by the Espeleo Club Tortosa. On the left, Els Penitens connects to the big aven in Toc Gallery. Last, is a passage leading through several maze areas (not totally pushed) ending at a climb at a draughting choke which may be easily passed. This choke was investigated on a visit in the summer 2008 and found to start with an awkward climb that requires a ladder. This passage runs parallel with the main passage leading to the Second Abyss.

Boxhead Traverse runs around the right hand side of the Second Abyss, which drops about 50m to a choked outlet at the bottom. A continuation of the large passage soon closes down, but a climb up through a narrow, loose rift on the left hand side eventually gains a large chamber. After a number of huge blocks have been negotiated, a 5m pitch at the back of the chamber soon chokes after a few metres of passage. There appear to be some phreatic tubes present part way down the Second Abyss but these would require a bolt route to enter.

A small opening in the left hand side of Galeria de los Elefantes, just beyond the First Abyss, leads to Helictite Maze, where there appears to be many ways through. Beyond a section of helictites, a junction floored with limestone pinnacles is reached. To the left the passage rejoins the Crystal River passage going west, that enters the other side of the First Abyss. (This provides an easy alternative to ascending the far wall of the First Abyss. To the right, the passage degenerates into a crawl, Cobra Passage, joins an abandoned stream canyon. Upstream leads to a calcite choke, downstream to an aven and continuing unpushed passage.

During the summer of 1995 the western streamway was pushed. An obvious inlet on the left hand side may be followed into a low passage which eventually enters a chamber. An abandoned route also enters the chamber from further upstream as well. Several small streams cascade down a massive choke which has been partly explored but no route through has been found. Continuing upstream in the main passage, the roof lowers until a crawl meets an area of collapse. One route has been pushed which enters an aven, choking after a series of climbs (about 15m). Part way up, a small tube to a grotto can be squeezed past and a tight right continues northwards - Crumble Passage. This has not been pushed to a conclusion.

Toc Gallery is a long stream passage entered by climbing up a slope on the right at the start of the Rio Grande crawling over gours and descending a mud slope to drop into the walking-sized stream passage. Beyond the Hale Bopp Trail and the Rope Climb Series, Toc Gallery continues past a huge aven (the Tocadome, a height measurement by Disto in 2006 was 75m and is "nowhere near the top") to a choke where handline climbs up and down regain the streamway. The September 1994 extensions - Galeria New York City - lie at the end of Toc Gallery and need a description. A trip in 1998 found that the draught in was lost near the end up a 10m aven where a hole is crossed in the floor.

Further extensions at Whit 95 need the survey data entering and a description. (J. Palmer).

At Easter 97, the Hale Bopp Trail was entered off Toc Gallery. This sets off about 80m upstream as a small inlet entering from the right hand side. The Hale Bopp Trail starts as a tight meandering streamway containing a noticeable draught. At 40m, along a dug calcite squeeze in water marks slightly easier going and, after an attractive orange-yellow calcite floor, a short climb up marks a change in character. The rift becomes very awkward and then suddenly enters through the floor of a large, high chamber running north-south. A slippery climb up at the northern end leads to a small passage and large calcite formation. A climb at the southern end, where the inlet water falls from the roof, eventually leads to a junction: straight ahead chokes but a hole on the right hand side gains several small interconnecting chambers. From here, a small canyon passage carrying a strong draught leads to a calcite blockage which may be dug. (Catalans 13/8/97?)

In 1998, a passage to the north of Hale Bopp, the Rope Climb Series was entered. After a muddy climb on the right, about 160m of muddy rift passages were surveyed ending at a tight, draughting climb up which is worth returning to. A branch on the left ends in the roof of Toc Gallery. There is also a possibility on the other side of Toc Gallery which will require a bolt to reach.

In the same year, the Catalans climbed up 15m at the start of the chamber north of the Maze Area (713,334) and enter the Resistance Gallery - an inlet which ends at two avens. To the south of this, and to the east of Shatter Passage, various maze passages were surveyed during the summer 2007, totalling about 100m.

Over Easter 2006, Birds' World was surveyed (batches 182 - 184), although most of the passage had probably been previously entered by the Catalans. Proper description required.

OBA water tracing
   A diagram of the hydrology has been prepared for a optical brightener test at Easter 2015.
   At Easter 2015, four litres of Leucophor were placed in the river just upstream of the confluence of the waters from Vallina I and II. Detectors were placed in Cueva del Comellantes (40), Cueva del Molino (resurgence) (791), Fuente de Barcena Morel (3278) and the Bustablado river just down stream of the main resurgences on the south side opposite Molino. Detectors were also placed in Cueva-Cubío de la Reñada (48), at Sump 1, Squirrel's Passage and the stream below Castle Hall. After 8 days of negative detectors, the detector in Cueva del Comellantes went strongly positive. Subsequent checks on the other detectors showed them all to be negative apart from Sump 1 in Reñada which was also strongly positive. This test confirms that Vallina and Reñada and Comellante are part of the same system, and that Squirrel's Passage water is an inlet and not part of the main river that flows out of Reñada II and into Reñada I via sump I.
