XXXXko lanak dirazela eta, kuebian sarreria ahal danik eta zihetzen berkokatzia tokau da, barruko topografiak kanpoko interes lekuekin kuadratzeko. Ni neu -zelan ez- galdu xamar ibilli naiz, baiña lasai, bestiak ondo zekixelako nundik nora ibilli. Sasi artian telemetro/iparorratz/klinometruakin bizpahiru orduko "crossfit" saiua egin ostian, pozik itzuli gara eta tabernan emaitza preliminarrak ikusi doguz. Seguro gaurko biharra mesederako izango dala!
Iñubija I. Aspaldi gabiz komentatzen Amildegiko Katazulo osteko
galerixetan, 2007tik pendiente dakagun rebisiño hori egin bihar
dala. Horrenbestez, domeka goizian zeozer egitteko 4 lagun juntau garanez,
bertara hurreratzia pentsau dogu, batez be pistian, bidian, eta
instalaziñuan egoeria ikusteko.
Pistiari dagokixonez, leku batzutan apurtuta dago (betiko legez), baiña ez dago zulo terriblerik, eta beraz kontuz kotxiak beheraiñok hurreratu geinkez.
Aparkaleku ingurua nahikua aldatuta dago, eukalipto gaztia sartu barri, baiña bidia libre xamar.
Behiñ Iñubija I-en, lehelengo sokia egoera onian dago; bigarrengo putzuan, instalaziñua duplikauta egon da, soketako bat "lora" askokin (kendu egin dogu), eta anklaje batzuk be aldatu biharra. Taladrua eruan dot, baiña... barautsik ez!! (petate aldaketa baten galdu dot), beraz hurrengo baten egin biharko da.
7a+ Gelaraiñoko sokak egoera onian egon diraz. Bertan Maalerrekako urteeria seiñalau detset (beste egunen baten bertatik urten nahi badabe), eta kanpora hasi gara sartutako bide beretik. 15:00etarako kanpuan egon gara, koba politt honetan zihar egindako ibillaldixakin pozik.
October 13-20: Santi (ADES), Torben, Louise, Karen (Denmark) Dave, Peter (UK)
Santi, Peter, Dave, Torben, Louise and Karen carried out a number of caving trips between the 13th and 20th of October in the Matienzo area, mainly following up on work previous carried out in October 2025.
On the 13th of October we entered Espada (#0103) by the new top entrance. The previous year we had put in a lot of effort to dig out at a high level, due to the flood risk the cave can pose in heavy rain. The top entrance was finally opened at Easter 2025, and we were now going to check out possible leads. First of all, we spent a lot of time taking photos of this very well decorated area of the cave. Secondly, we checked out an interesting area, identified by us many years previously and shown on the survey as “complex area, drawing needs checking.” However, with time running out we decided a return visit would be needed to survey what turned out to be much more than we expected. This would have to wait until after we visited Vallina on October 14th.
Vallina (#0733): just beyond Windy Corner we turned our attentions to the maze area and a passage leading off known as Shopping Trip. After passing a few short but tight dug out sections, we decided that the original explorers had been very determined and we unlikely to get any further, so we concentrated on checking the survey of the maze. This turned out to be very accurate with only a climb noted that may not have been seen. We continued further into the cave to see the Dragon and check out the Who Knows chamber. We decided to re-survey a section of the chamber using our new high tech kit - a Pony and an old Samsung phone. The chamber climbs steadily and reaches a level only 50m below new passages found in the higher level of Vallina, which still need pushing. One of the pitches may well connect to the Who Knows chamber eventually. The surveying went well, and we learnt a lot about using technology underground. More practice will definitely be needed. On the way out a few more interesting areas were noted and will be visited later.On the 15th of October we decided to visit a number of small caves in the Cubija valley, starting with Cuvia del Campo #0076. This is short, but a large section of well-decorated passage heads straight into the hill. We took a short section of ladder to check out an Aven, but it only went about 3m before closing down. We exited the cave via Cueva del Porton #1403 after checking out a very small hole between stal. On the opposite side of the valley and only a short walk away is #0525: we saw a wild cat at the entrance, so renamed it Cave of the Wild Cat. Just inside the entrance we removed rubble and a few boulders improving access to the 11m pitch previously seen (Easter 2025) but still not descended as more work needs to be done to make it safe. We then surveyed the cave and proved that a second, shorter pitch was very close to the top of the 11m pitch but not a viable alternative.
On the 16th of October we returned to Vallina, firstly bolting up the pitch found in the maze area, but part way up evidence of it previously being climbed was found, so we left it to carry out more research before a possible revisit. We then headed for the corkscrew climb which has only been done twice before (in 1989, both times by Peter and friends), but proved to be far more difficult in old age and would require rigging and treating like a pitch (18m). After rigging a short traverse above the pitch, we found and surveyed approximately 60m of un-surveyed cave with the possibility of more in the future. On the way out of the cave we took a few photos of fossils found by Santi and put them in a safe place in case they needed closer examination.
On the 18th we returned to Espada #0733 to push on in the complex area, and descend the pitch found on the 14th of October. Peter and Santi managed to free climb the pitch which entered a section of passage over 3m wide and high and sloped down to a choke after 8m. A short section of tube quickly choked opposite the point of entry. A future visit is planned to dig the choke. Between us we managed with a little difficulty to survey in this new area and carry on through more short sections to a passage 130m in total, mostly leading to avens (one around 7m high). This was tied into the main cave at the base of a bolted climb. On the way out we decided to check out one more lead which required a bit of acrobatics to enter via a chimney then a low crawl to a dig. We dug through quite quickly to another well-decorated section of cave and a further dig which we will visit in the future.
During the week we spent with Santi we managed to push, survey (over 180m of new cave) and photograph some very nice formations, as well as advancing our knowledge in the use of technology underground. As usual we plan on returning in 2026 to finish what we started, but we all know there are more questions than answers.

Ondarrun, Zientziaren Giltzak elkartearentzat hitzaldia eman dugu. "Lurpeko mamarruak" izenburuarekin, orain bioespeleologian barneratu gara (aurretik espeleologiaren beste arloei buruz emaniko hitzaldiak konplementatuz), 50 bat ikusleren aurrean. Bistan denez, 2014tik aurrera Gorozika auzoan eginiko aurkikuntzek leku berezia izan dute, eta galderak ere makinatxo bat izan dira, beraz badirudi gaiak interesa pizten duela. Plazerra da, horrelako publiko fiñaren aurrean berba egitea!
EEL Simulakro Orokorra (Kobeta, Mutriku). Ariketia 2 erreskate paralelotakua izan da, Kobeta I eta III lezetan; bakotxa bere PBakin (bata Tedraz, bestia Nicolaz) eta bixak PCakin irratiz komunikatuta. Dakixeneri entzunda, dana ondo juan dala emoten dau nahiz eta, betiko legez, hobetzeko egon dirazen txikikeri zerrenda ugarixetatik ikasteko aukeria be egon dan.
Galder eta bixok Kobeta I-eko COM postu bakarran arduria eruan dogu: fondoko taldia (Esther) eta sarrerakua (Oskar Latasa) lotuta. Gure bihar nagusixa barrutik kanporako informaziñua bialtzia izan da, PCkuak kontrolerako; horretarako, Galder juan-etorrixan ibilli da, informaziño hori COM postura ekartzen eta bide batez handik eta hamendik laguntzen, eta operatibuan parte diferentiak ikusten. Ohikuak dirazen itxaronaldi ultra-luzien eta hipotermia aldixekin batera, beraz, entretenitzeko aukeria be izan dogu.

QS (Quincoces de Suso). Oskarrek eta Carlos Takomanok osatutako urpeko dream team laguntzen, Sistema Fuente Suso esploraziñuetan. Atzo 8 laguntzaillekin materixala sartu eta gero, gaur beste 6 bildu gara inkurtsiñuan ostian gauzak etaratzeko. Bittartian, emaitza onak: 18 ordutako jardunaldixa, 04:00ak arte, itxuraz Mallinsonek eta Robertok ezarrittako puntia gaindittuta, eta 700 m barri esplorauta. Gure aldetik, 4 sartu gara, kanpora zetozen Isra eta beste batekin kruzauaz. Ruben eta Esther 1500 mtako sifoiraiñok aurreratu dira, eta Galderrek eta bixok handik 3na petatekin bueltan zetozela topau doguz, 1000 m inguruan, kargia partidu eta kanporako bidian laguntzeko. Bizkarreko muskuluak ederto behartu eta gero, eguzkittan allegau gara kanpora, Burgosko ordokixen haize sanua eta paisaje politta gozatuz! Domeka goiza pasatzeko modu ederra.
