2. Matienzo 2019 Sites and projects to consider for Easter and Summer

3. DIGS • South Vega: 4853 & 4854 – two sites high (630m) up but below ridge, above Volcano. Water heard running away in heavy rain. Need an exploratory dig. • Seldesuto: 1298 – Site dug to pitch into a boulder chamber – way on needs snappering and best to-do on very hot day i.e. with good draught to check way on (maybe better in summer?) • North Vega: 4716, 4645 – sites high up, 1st needing capping to open rift, 2nd in wooded depression • La Secada: 603 (Near the bar pot); 252 (4732); 880 (Two & half fat ladies); 4805;– key digs to get access into SW area of Four Valley System (FVS) - 1017 (Socks) between N Vega and FVS, current dug • Fresnedo: 2522 – dig that should give access direct into the far end of Rampant Rabbit passage in Cueva del Torno, good progress in 2018 likely to only need a few days more work to get access. • Riaño: 1800 (Fridge door cave) – if dry to dig blockage to connect to 0103 (Cueva de la Espada) • Riolastras: 4781 new shaft found, not descended or dug • Coterón Las Llanas: 4806; 4807 - to possible fenced shafts need checking out (seen from drone) • Hornedo: 3048 - dig with good cold draught between Vaca and Nabo is worth an exploratory dig • Cobadal : 4846; 4847– 1st opened to short passage, more work needed; 2nd small hole needs work to get to possible chamber.

4. Caves to push and survey • 4669: Torca del Dron – entrance via an adjacent cave needs sorting, and possible side galleries entered, pushed and surveyed. • 0048: Cueva-Cubio de la Reñada – continue re-survey beyond breakdown chamber. Enter, explore and survey ramp in Itchy Crutch Series • 0713: Fuente Aquanaz – pushing Sarah Jean Passage; Rudolph Chamber and end sump area. • 3234: Cueva-Cubio del Llanio – trying to find link to 0105 Cueva de Riaño • 0071: Torca del Mostajo – push and survey work between Golden Void and possible link to Manchester series. • 0892: Torca del Regaton: dive sump off Spike Hall, push leads on survey marked with “?” on Sistema de Cubija survey. • 0107: Cueva Hoyuca – push Trident area via Carcaviezo • 0780: Torca de Corcada – continue capping and pushing at end of Fossil Route • 0427: Torca de Lastrilla – cap slot at bottom with possible link to 0075 Simas del Picón

5. Caves to push and survey • 0841: Cueva Fresnedo 2 – pushing at the passages and leads at the far end found in 2018. • 0733: Cueva Vallina – downstream (Rupert) and upstream Rio Rioja plus pushing etc in Vallina II and Sisters of Perpetual Indulgence areas • 1930: Sumidero de Cobadal – snapper and digging work to get up strongly draughting choke at western end. • 1800: Fridge Door Cave – diving, pushing and surveying if water is low enough in entrance area. • 3991: Cueva de Lolo (del Secretario) – digging out gravel from sump and pushing open passage beyond. • 0333: Torca de Azpilicueta/Reñada – pushing above western end above where water last seen/heard. • 1391: Volcano Cave – installing some shoring and pushing down what looks to be open draughting leads at bottom.

6. Project Work Needed • 2691: Giant Panda Entrance – work to stabilise entrance and install tube. • 3916: BigMat Calf Hole – concrete and block work needed and remove much of scaffolding. • 1930: Sumidero de Cobadal – open up collapsed entrance and secure, possibly with tube. • 0081 Cueva de Carcavuezo – check entrance and clear out as needed • 3334: Road Works Pot – not now in our area, but we have some responsibility as our “guarding” chains have disappeared – to install some steel bars to stop accidental access by children and animals. • 1452: Hole in the Road – gate or similar needed to discourage child or animal access

7. Surveying and Recording • Have OruxMaps and its data downloaded from website, plus site descriptions, from website, on your phone/tablet. This will allow known sites to be identified and so new sites recorded, by GPS grid ref, photograph of entrance (close up and distant), and a brief description (size, approx. depth, if draughting etc). • If new site or new cave passage explored please survey all significant finds (use what method you are familiar with) but please record: The centre line plus LRUD at each station, and critically recorded good passage details (water flow, air flow, formations, floor type, faults etc) and cross sections at relevant locations. Try to take photographs/video of typical passages, at this point they need not be competition quality, they are for record purposes. • Write up finds as soon as possible after in log book (fresh in mind) including a brief description of new sites and passages found. And input photographs and surveys. If not drawing up survey immediately leave survey notes (if on paper) in a plastic A4 cover in the Matienzo Office ensuring the site and location is marked on the notes.
