Torca del Oso Caido (Fallen Bear)
On the northern slope of Samelar is an area called Brañaredonda, where Torca del Oso Caido or Fallen Bear is located. In the 70’s LUSS explored down the main pitch and discovered a few smaller pitches before leaving the cave to explore elsewhere. AD KAMI revisited the cave in the 90’s and allegedly moved a small rock at the foot of one pitch and discovered nearly -400m depth of new cave. Accurate descriptions of what is at the end of the cave, vary from ‘nothing’ to a half-submerged passage onto an undescended 40m pitch.
The nature of the cave passage (huge ramps) is similar to Nacimiento and the location places it coming down the mountina between Nacimiento and Rio Chico, so a cave of much interest. Finally, on this expedition I was able to convince a number of people to visit and report back.
Friday 14th July (Chris Jones, Hannah Moulton, Emma Battensby)
Excited by the prospect of some sunshine above the cloud at the top of the hill, the air conditioned drive to the White House was enjoyed. Armed with two different sets of GPS coordinates (following a very quick lesson) Emma, Chris and Hannah set off on a bear hunt. Initially following the LUSS coordinates we located an entrance below the Bejes track. Having decided that the entrance did not match the (minimal) description of Fallen Bear we figured out how to input the AD KAMI coordinates and continued to search. These took us above the road but to no avail. It was clearly lunchtime. Tasty sandwiches and tea (from some lovely thermos flasks) were enjoyed before deciding to drop the entrance on the LUSS coordinates just to be sure. Whilst Chris and Hannah kitted up, Emma wandered down the track to try and make more sense of the description from Bejes. After watching Chris and Hannah disappear down the shaft Emma walked back up past the White House to join the team at Castillo/Segura II, narrowly avoiding being mauled by a large, scary canine!
Hannah rigged, following spits. Chris followed surveying. ~70m deep. A small climb at the bottom (not previously passed) lead to a small sump (5-10m of passage). De-rigged.
Saturday 15th July (Hannah Moulton, Chris Jones, Bob Clay)
Previous coordinates followed to exact location as yesterday despite grid change. Kit retrieved from Friday cave and mark followed back to GPS point successfully.
The entrance shaft was cool. Hannah rigged with an entourage of birds flying around. Chris and Bob followed doing an awful survey (an 18m leg is missing between stations 3 & 4…). Hannah was located happily rigging on the way we’d decided to go while Chris and Bob looked at some dead dogs. When it became clear it lead to the LUSS deep point it was de-rigged and the main chamber explored to find the way on, which continues under a breakdown chamber into smaller ancient phreatic passage, where the bear lives.
Sunday 16th July (Hannah Moulton, Chris Jones, Bob Clay)
The 1996 KAMI route was located by passing the bear and dropping the 13m shaft. A small muddy ramp leads to the ‘50m pitch’. On the way a small down climb lead to a short continuation, but it did not go. The 50m pitch was a long ramp, split by a breakdown chamber and a stal ledge, was very Aguaesque. Part way down a parallel shaft was spotted through some stal, Bob bolted his way down this while Chris and Hannah began to explore El Chaos. One lead (window) in the ceiling was spotted early on which would require a short bolt climb, not that promising to be fair. The Chaos is fairly chaotic. We returned to the base of the 50m pitch to cook Bob some lunch and returned to the surface, his shaft went down ~12m, where he could get off the rope and walk to a large clean aven, a further short pitch lead into a meander back under the original pitch, no way on. The remaining kit was stashed at the base of the entrance shaft (which probably needs de-rigging). There is a lot of air movement in this lower part of the cave and it is cold!
- A good sling is required to replace Chris’ belt rebelay at the top of the 13m pitch.
- A deviation just above the 1st ledge on the main pitch would be nice to reduce a short section of rope rub (which can be avoided with long legs or a walk along the boulder ledge).
- Kit left:
- 1x petzl portage + Dick
- 50m and 20m static
- Hitachi Drill (TL)
- 1 full drill battery
- 2 drill bits (TL and PW)
- 1 Hammer (CJ)
- 1 Skyhook (CJ)
- Electrical tape
- 4/5m 6mm cord
- 16 hangers (NO BOLTS)
- 4 hangers (with spits)
- 21 maillions
- Survey and description of cave
- No deviation krabs.
Wednesday 19th July (Dave Powlesland, Tom Lia)
The night before had started with extensive planning and much deliberation as to what we were going to look at in Fallen Bear Cave… Although the bar had distracted us a fair amount, leaving us weary for our early start when we awoke the following morning.
So we had an early 11am start (expedition early) we marched up the hill via the many shortcuts to be at the cave for around midday. Neither of us had been down the cave before, but heard route finding was a blast. After a quick descent of the gaping gill sized chamber we immediately got lost. EAST WEST EAST WEST – — – – -yes the old description was incorrect!!!! After finally finding the correct direction out of the way down to the end of the cave we swiftly descended through a maze of smaller, tight pitches to El Caos (after picking up drill, rope and bolting kit from the main entrance chamber).
As per previous reports…. This really was the CHAOS!!! (El Caos) Fallen, stricken, loose, dodgy, formidable boulders everywhere we could go. We continued down a 45 degree slope, over boulders, loose rocks and mud. Several free climbs and a few scree slope traverses lead us eventually toward the end of the broken down passage. But this wasn’t the end of it. The height of the passage reduce to body width, where we had to thrutch our way down and through the narrow, low passage.
Several attempts at finding possible side passages and unexplored areas had lead us in circles with only a few small avens confirmed as possible leads. As we progressed to the lower reaches of the cave we encountered the lower pitches that Dave swiftly drilled and rigged for us to continue. We dropped the ‘27m’ pitch that soaked up a 50m rope (left rigged). This whole section a cave is a bit of a variation and the pitch we rigged seemed the most straightforward to descend. After a crawl through boulders and a short squeeze, we popped our head over the final pitch, which was described as a 37m pitch, however it looked as though a 50-60m rope was needed. The final pitch into the chamber was very impressive and presented a different character to the rest of the cave, this was an atmospheric wet, draughty cold chamber. One of our aims was to see one of the marked avens at the top of this chamber. There is clearly a large window with a mender/shaft heading away from us, and away from the rest of the cave. It should be aim of the next expedition to push this meandering window to see if it links into another system.
AAARRRRGGHH FLAP FLAP – ARRRRRRGGGGHHHHHHHHHHYYYYYY (Dave says) but the flap was not from a human ….. It was from some sort of beast!!! FLAP FLAP the beast (small bird), was a crow, who had chosen to make its nest in the entrance shaft. The crow perched itself on Dave’s shoulder in a displeased manner. Tom had no such problems. The crows were merely dispersed by a swift backhander.
Entrance pitch derigged – need deviation for very top – need deviation for ledge half way down main pitch. 79m pitch marked – say 60 and 40 would work well on re-rigging.
50m rope required for lowest pitch
Lightweight aid climbing gear for numerous marked leads on survey at lower areas of cave.
