Expedition log, Summer 1975
This is an account of the 1975 Oxford Expedition. Its six-week mission,
to explore strange new caves, to search for the paintings of prehistoric
civilizations, to boldly go where no man has ever been before. Transcription
of the expedition log.
18.07|| Left Winchester 7:30pm in Bill’s white
3-wheeler Reliant van.
19.07|| Up at 04:30; boat to Le Havre. Off boat
07:30; in Spain by 23:25, camped Rosaleda (near frontier).
20.07|| Left Rosaleda 10:00; at Posada 17:05, met
Steve Norton and Martin Laverty who had arrived just 10 minutes earlier.
Celorio Fiesta for a brief visit (boring). Then to Llanes for meal.
Camp site at Rales field (as in 1973 and 1974).
Off to Tinganón for surveying; in at noon – undergrowth not
too bad. Surveyed to grade 5d (we thought at the time), out at 17:30.
Standard curry meal then went to Posada for a few drinks at Acuario;
back just as thunderstorm started.
22.07|| Tuesday. Up at 09:30. Still heavy rain,
so off to the bar in Rales to calculate some of the Tinganón survey
figures: closures awful. Rain stopped, so Bill later goes to Llanes
(twice) to check for arrival of Bluewater parcel (for Victor). Steve
and Mike get some prusik practice on the cliff above west San Antolín
beach. Martin mended wetsuit and had boots thrown into the river
by a local lad. Later still, to Rales bar.
23.07|| First to Llanes for shopping to replace
Martin’s boots, lost in river the previous day. Then Mike, Bill,
and Steve into Rales system
– collecting water samples at bottom and middle of streamway and
also at Samorelli sump. Then back down streamway, exiting at Fuentica.
Four and a half hour trip. Curry and Rales bar again.
24.07|| Eventually went to Trumbio area. Martin
& Steve had a look for Cueva Rota – found a 10m-long hole which
was probably it. Meanwhile Bill & Mike descend Trumbio (2.5 hours),
taking a few notes and cross-sections. Strenuous scramble on boulders
etc. plus a 10m pitch into huge chamber 60m × 60m × 200m
and a stream that sumps.
25.07|| Bill walks to Rales upper sink and Polje
(beyond Samoreli) – Vizcaina; Steve & Mike to Cue – found sea caves
and suitable abseil/prusik practice cliff. Martin got paid for boots.
Posada fiesta that evening.
26.07|| Swimming + sunbathing + sunburning at Barro
beach. Drove to El Mazuco for a walkaround and sight-seeing trip,
then back to Barro for steak and chips supper.
27.07|| Drew up Tinganón working survey in
the morning; Steve attempts to get bread in Posada (unsuccessful
as Sunday). At 5pm the secret weapon of Rales (Steve & Martin) took
part in a Rales vs. Balmori football match; Bill and Mike took photos
[none of which seem to have survived]. Spaghetti bolognese
28.07|| Off to the Llamigo area. Steve & Martin
walked looking for new caves – several caves and other suitable
sites were seen and heard about – worth a return visit. Mike &
Bill carried out a grade 3 survey of Llamigo cave (250m surveyed).
(Only grade 3 because the OUCC clino didn’t work, but the cave was
horizontal). Drew up survey in the evening and ate beef Newton!
Cracked a bottle of Sidra and three eggs.
First event of the day – a snake in Bill’s tent about 60cm long,
brown and evil looking – eventually chased off with a long branch.
Very hot walking around Vizcaina and Rales system: Martin, Steve,
Bill went up to the Vizcaina sink (50m grade 1 survey made) – very
wet, and choked with flood debris (wood). Martin then walked around
to La Fuentica, messed around in entrances, and found a new passage
(up for 10m) which connected with the upper series. Meanwhile, Steve
and Bill foolishly climbed up to Samoreli in wetsuits, got lost,
but met a farmer who “saved their lives” with copious quantities
of water. In Samoreli, looked at the ‘sump bypass’ – definitely
previously explored – and surveyed the upper entrance passage at
grade 3b. Then down Pozo del Molino and streamway to detackle and
take photos. ‘Lack of communication’ on the lower pitch. “Bill,
the rope’s not long enough” ... “I’m coming down now...” ... “YOU *?!!*?!”
[sic]. As neither were carrying prusikers (fools) the
last 15′ down was a little awkward, and the rope was left a-hanging
in the void. Return trip after a meal and a beer, equipped with
dozens of prusikers, to retrieve said rope and descender.
30.07|| Off to Fuente Dé and 1 mile up using
the Teléferico. Fine weather; invesigated threshold of a mine and
snow patches, poljes etc. Then in 20 minutes a thunderstorm blew
over – hail; rain (lots); lightning etc. and a walk in the rain
in thunder. When we eventually got down, stopped in La Hermida for
paella (628pts all total) and arrived back in Rales at 23:30
in time for a quick drink in the bar and to investigate lighting
habits of glow-worms.
31.07|| Returned to La Hermida gorge and looked
at Spanish group’s map of Pozo del Infierno at their campsite across
the Coto del Infierno bridge. We then took an hour to climb up the
mountain and find the cave. Handline too short on 2nd ramp. Continued
to PdI 2 via handlined climb from water chamber – via various lakes
and boulder ruckles to “el final”, the sifon. Actually,
the so-called sifon is merely a duck, and bypassable too, so we have
agreed to return tomorrow to show the Spaniards the lake which lies
beyond. Bill won ‘Dirty Pig of the Day’ award for having a s..t
100′ from the entrance and within sight of daylight.
01.08|| Mike & Bill arrived at Coto del Infierno
at las dos y media (14:30) and chatted for an hour before attempting
the climb to Pozo del Infierno.
| 7 Spaniards carrying rucksacks and boats etc.
accompanied us to their campsite where they put a tent up(!) in a
big dry chamber, the ‘Talps gallery’. On the way Mike broke a screw
on his battery top – write off! Generous Spaniards lent him a carburero
de auto-presión complete with helmet. Exploration then commenced.
At the lake 2 Spaniards pumped up a substantial dinghy and Mike &
Bill, in wetsuits, pushed them across. One is just out of one’s
depth in places and the water is very cold. As expected there was
a boulder ruckle at end of the long meandering lake. One side passage
Pozu del Infierno campsite
We left the cave at 21:00, climbed down the mountainside
in our wetsuits, and had a much-needed swim in the river at the bottom.
Then have supper with 4 of our hosts in the valley below – a simple
dish of chickpeas in packet mushroom soup; so hungry it was one of
the best things we’d ever tasted. Left at 00:30 and arrived back
in Rales at 02:00.
In Pozu del Infierno
02.08|| General ‘Recovery’ day. 3 went to Llanes
after meeting Steve Evans on the road between Posada and Rales; shopping,
money-changing, photocopying of surveys, etc. Set up large tent
and then spent evening in Rales bar.
03.08|| Spent morning packing then off to Lago
Ercina in the mountains via Cangas de Onís. Set up camp at ‘old
Spanish campsite’ to southeast of lake, then down to the local lake
bar, “María Rosa”, where locals were fascinated by our carbide
lamps. Bill, Steve E., and Martin had a walkabout – in the rain.
| “Arriba, arriba” at 07:30 ... National
Park Warden wakes us, objecting to our presence: told him we were
waiting for the Spanish cavers and he agreed to let us stay the day.
Then met a group of French cavers from SCAL (Spéléo-Club
Alpin Languedocien) Montpellier who were camping in the car-park.
Later Bill walked towards the Dobra gorge (without getting there);
Martin also had a walkabout in the same area. Mike & Steve N. followed
Steve E. to a cave noticed the day before. Unfortunately the latter
could not find it & so walked for two hours over the mountains.
In the evening all went down to Cangas for a meal after moving camp
down to the car-park and having a long chat with the French.
First camp near Ercina
| Those sworn to swimming in the lake chickened
out with excuses such as ‘there are fishermen (3) along the bank’,
‘it’s too dirty’, etc. Bill & Steve N. went down to Cangas for petrol,
money, and food at a restaurant there. Mike spent four hours looking
for Pozo Palomeru – unsuccessfully. Martin & Steve E. set off towards
Forcau. Found very promising extensive area of limestone with shafts
etc. Meanwhile Bill & Steve N. looked around the Beyos Gorge and
found Cueva de Buseco – large and dry. Not fully explored as ‘populated’
with local kids. Very merry evening with French and some Spaniards.
Ercina and Peña Santa
06.08|| All looked for Pozo de Vega el Forcau, eventually successful after descending several shafts and
Bill had asked a shepherd. Exploration was hampered by the heat
of the sun and hangovers; prepared tackle for exploration the next
07.08|| Got up at 07:15. Joined the French from
SCAL at 09:00 (Philipe Altairac, Veronica, Martin Figere, Sallia,
François Henry, Gilbert, Pierre +2, Alain Ottan).
Two parties to cave, the first enters at 12:30 (including
Mike & Steve N. & François) and the second 15:30 (Bill +2),
who meet François at top of the 5th pitch. Steve E. climbs
On the way to Forcau
Descend six pitches: Entrance pitch 11m free-hanging, scramble down
loose rocks to tighter passaage to pitch II, 8m. Pitch III (estimates
vary 8–15m). Pitch IV 7m. Pitch V difficult to get on to, 37m free
hanging – superb pitch. Pitch VI a) 5m, b) free climb 4m, c) 25m
top part climbing free hanging lower part out of waterfall. Tight
passage leads off from lower chamber – high narrow rift, very hard
work. Mike and Steve after puching this retire at 18:00.
Second party leapfrog first and on down. Pitch VII (9m into streamway)
required a bolt and this was a general excuse for a stop and a meal
of dried apple, sponge fingers, cheese, sardines, hot sauerkraut
From here on the supposedly open passage did not really open out
– meandering stream passage, only 0.5m wide, with puddles and pools.
After 100m character changes to very sharp projections on walls.
After another 100m, at −160m, we stop for a sing-song La Rirette (Jeanneton prend sa faucille) whilst Pierre(?)
explored ahead alone for another 200m to a duck where he turned back.
(Editor’s note: there were simply too many people in a tiny passage.)
Returned to chamber below 7th pitch for coffee!
Meanwhile Gilbert, who had gone out with Steve & Mike, had not been
able to get up the 6th pitch. The 3 had arrived at that point at
19:00 and it was now 21:30; Mike having climbed the 5th pitch (37m)
& had come back down to help Steve get up. The rest of the party
arrived at the bottom of the 6th pitch at about 9:40. Mike then
climbed the 5th pitch for the second time and after waiting there
some time exited at 22:30 followed by Steve and Philippe at midnight.
Meanwhile back at the 6th pitch...
Gilbert had another attempt at climbing the 6th pitch – unsuccessful!
We discussed the idea of leaving him there and returning with SCAL’s
ladders. At last he did ascend, slowly, and Bill followed, reaching
the 5th pitch at about 23:00. Here we all waited while Gilbert ascended.
After 90 minutes, Bill ascended a little faster. The next pitches
were rather tiring as there was nobody below Bill to put weight on
the ropes. Whilst near the top of the 3rd pitch Bill experienced
a fall of nearly 1m as the snagged rope slipped above and boulders
crashed down! Meanwhile Gilbert was puking above. Bill exits Forcau
at 02:00 and the party rests and eats. (The bread tasted so good
in spite of, or even because of a slight dusting with powdered carbide!).
Back at the camp-site at 04:00.
08.08|| Rain. Move back to Rales. Martin stays
behind at the Lakes.
09.08|| Bill & Mike return to Bilbao via Cueva
de Sangazo (correct name is Cueva de Lastrilla), near Castro Urdiales.
Mike returns to UK. Steve & Steve find a sea cave west of San Antolin
and a small inland cave.
10.08|| Steve N. drives to Los Lagos. Steve E and
Bill swim at Barro beach – lunch in Marías José & Carmen’s garden.
Steve, Bill, Ely, Conchita, Mari Luz –> Porrua fiesta –> Rales
and awaken Anne & Laurence!
11.08|| Steve and Bill return to the lakes; François
leaves for France. See Victor (Jose Manuel Victorio) at midday.
Steves & Bill have lunch and find cave and explore surface on road
to Demues and hear of caves near Llano Con. (Cueva del Agua – explored
12.08|| Look for cave at Covadonga, Cueva de la
Campana (sp?), but find another instead with waterworks. Steve and
Bill examine Cueva del Agua flood entrance (leads to pitch) and also
find other small spring/cave further up the valley. Victor Blanco
(from Mexico) shows us entrance to Cueva el Osu.
13.08|| On the way to Rales, Bill finds the real
Cueva de la Campana; Martin and Bill find small resurgence at Santianes;
walk up valley to Arroyo de Llovio and beyond to Cueva Negra.
14.08|| Ramblers arrive. Steve & Bill pick them
up in Bilbao. No sign of Penny Friedlander who apparently decides
she’s not coming.
16.08|| Cares Gorge walk to Caín and back.
17.08|| After 2 tortillas (dobles), Chris,
Steve, and Bill explore 400–500m of Cueva Negra. Stopped
by 15m (est.) pitch. Very like Lledales (see below). Steve
falls in pool of cowsh. Returned through Cueva Tinganón.
Steve Newton meanwhile finds resurgence at Niembru.
18.08|| Fuente Dé to Carmameña via Bulnes
walk. Steve drives Chris, Bob, & Mike to Teléferico. Martin walks
towards Naranjo de Bulnes. Steve E is ill. Steve N & Bill find
Cueva Peñado (sp?) resurgence near Arenas (path is 2.4km from bridge
east of Arenas).
19.08|| Day off on Barro beach and in Posada for
lubrication. In Posada see photos of caves: “El Tebellin” (Bricia),
Jou Sanchez, El Conde, Jou Porquero, Jon Fria (30m, Niembro), Cebelin
(see Cox 1973).
20.08|| Fail to find/explore some of the above
21.08|| Rain. Festering. Walk to [unreadable
22.08|| Sierra de Santianes exchange walk. Re-identify
Old Negra = Tinganón system
Old Lledales = Cueva Negra
Old Jalcorneda = Cueva Lledales
Jalcorneda = impenetrable sink at cliff face
Fuente de San Juan at Santianes not investigated
23.08|| Take ramblers to Amieva. Bill, Martin,
and Steve (and Chris?) eat an enormous tortilla in bar for 80 ptas.
24.08|| Barro beach then –> Llanes for meal then
Barro fiesta. Mari Chielo pissed – declares her love and tries
to swim in the sea at midnight.
25.08|| Martin & Steve return to UK. Bill returns
26.08|| Chris and Steve leave at 08:00 for Peña
Santa. Bill walks down Dobra Gorge. Bob pukes.
27.08|| Take ramblers to Rales via Cangas and Posada
(conjuring in Café Moderno).
28.08|| Up at 05:30 and leave Rales at 06:00.
Arrive Bilbao at 11:00. Return to Pozo del Bosque picnic.
29.08|| Collect Steve from Amieva, via Tornin fiesta.
Posada until 03:30.
30.08|| María del Mar arrives. Hmmm. For
the whole of the weekend Bill is only conscious of the love birds
fluttering around his head. Marías Gloria & del Mar & Steve
& Bill go to Llanes. Bill wins 255 ptas at bingo in Acuario. Ballandro
[No log entry.]
01.09|| Wandered around Mestas, Riocaliente, Villa.
02.09|| More Tinganón surveying. Letter from
03.09|| Barro; not much sun.
04.09|| Rain. Steve leaves. Bill to Potes, Pineres,
La Fuente: drove from Potes via La Hermida and up the recently tarmaced
road (great improvement after 1973!) to Linares, Pineres, and La
Fuente. Wine only 2ptas a glass in La Fuente bar! Am informated
of the following caves: A major resurgence (hence La Fuente) which
some say is enterable, others not; Trescuajara; Cueva La Nava (wet);
Pico la cueva; Resperda; Cueva el Sevo; some of these may have been
explored by a group from Madrid in 1974. Left during torrential
rain via Puentenansa. Bar has dyeline of local cave with paintings.
At Celis, reports of many caves including Rengones. Walk via dozens
of depressions up to 30m deep without any reports of caves in them.
Reach river Tanea. Cueva de los Marranos at river level (explored
by Manolocos de Madrid in 1973, 800m). Farmer shows Bill the Cueva Toyu entrance (unexplored); possible through trip following Río
05.09|| Drove to Mestas and beyond. Where the road
deteriorates en route to Riensena, on the left before the first hairpin
bend, is a track through the wood. It crosses the stream a couple
of times and if one takes the path to the left near a 1–2m cascade
one is within 30m of Cueva de las Inxanas (Chinchanas). The entances
are situated 20m up a steep undergrowth-covered bank and are in a
limestone cliff face. One goes 30m and continues. Real cave, not
just a rock shelter.
06-08.09|| Waiting for MdM. She arrives!
09.09|| Return to Venta de Fresnedo valley to recce
the six saddles and their cave systems.
Diagram of Caves of the Latarma valley, Venta de Fresnedo.
System 6 Riu Praucu Open resurgence entrance @498m
Sink @470m. System 5 (saddle @474m) El Seguedal Resurgence with stagnant
pool @442m. Possibly impenetrable.
Sink @423m. System 4 (saddle @430m) La Huerta Resurgence cave with
2 big entrances @386m. Grid 53289646. Length 130 m. Vertical Range
30m. Torca del Joyu las Munecas Big entrance @625m 4.3 km long,
Vertical Range 230m
Sink @ 381m. System 3 Comaria Open resurgence cave
@370m explored for 50m. Main Sink @341m Flood bypass sink @350m.
Cororigo System 2 (saddle @396m!). Resurgence cave @270m. Grid 53379646.
Length 204 m. Vertical Range 22m.
Sumidero (Cueva) del Toyu @171m. Grid 53499643. Length 1 km. Vertical
Range 64m. Sistema del Toyu System 1 (saddle @209m) Manantial del
Breno – impenetrable resurgence at river (Lamason) level @144m.
River resurgence into Rio Lamasón
Notes. All the sinks are probably impenetrable and all the resurgences
seem open cave entrances. An exception to this rule is Toyu for
which the contrary is true. The Toyu system is susceptible to severe
flooding and the water has been known to back up so high that the
water flows over the saddle!
10.09||Bill returns to UK via Bilbao ferry. Exhaust
pipe comes off 3 wheeler.
Other log details: Log includes diagram of Forcau pitches,
diagram of Latarma valley, some addresses of French & Mexican cavers,
and cumulative mileage/time chart driving through France and Spain.
