5th January 2016: With Tom Chapman and Duncan Price. Tav and the ATLAS team went on tour of the main passages.
The rock engineering applied last week had the required effect and access down through the slot was more comfortable. Before proceeding downwards a stainless steel hanger was inserted for a ladder and duly rigged. At the bottom of the slot I was pleasantly surprised by the continuing passage ahead but entry to this is somewhat constricted. The required engineering was carried out, kit and equipment packed away and we made our way out to meet some of the touring team who had come to see how we were getting on. Completed the task from the main passage and all was good. Made our way out of the cave to get changed and discuss prospects ahead at the Hunter’s Lodge Inn.
The arranged trip into Home Close Hole was binned due to adverse weather conditions – persistent rain and an excess of surface water. As part of the investigation of the source(s) of water flowing into Home Close [and Wigmore] we had planned to place activated charcoal receptors in the streams in various locations within the cave system as controls prior to testing.
The decision was made to check the water flowing into Tor Hole and Long Wrangle (pictured below) both possible sinks into the cave system. So set off with Nick Hawkes, Claire Cohen, Stuart MacManus, Pete Hellier and Tony Audsley to have a look. There was a lot of water flowing and it was probably not the best of conditions for the testing to take place, better to wait for more settled conditions as the hydrology project will require several consecutive weekends.
1st January 2016: Out for a walk with the dog on New Years day. Took an amble up through Ebbor Gorge up to Savory’s Hole. Off the beaten track it’s not so easy going there are a lot of trees down in the recent storms.
At Savory’s Hole it is quite evident that badgers are doing their best to backfill the cave. Mostly with the spoil from previous excavations.
Then up the hill to the ridge to take in the view, although it was a little too grey to get the full vista. There were a few areas of flooding visible out on the Somerset moors below.
29th December 2015: With Tom Chapman, Pete Bolt, Nick and Tav.
The start of the new mid-week project to extend Tom and Keith’s old dig.
No lights and music this week but we managed to find our way in and out okay. The purpose of this evenings jaunt was to apply some rock engineering to the constricted top of a slot down into the dig. This will ease spoil removal and, of course access up and down the slot. 4no. holes were drilled, charged and completion of task was from the top of the stal’ slope – all was good! Back next week to clear and drill.
22nd December 2015: With Tom Chapman, Keith Savory, Nick and Nicole Hawkes and Alex Gee.
A trip into Wookey 20 to assess the prospects of Tom and Keith’s old dig there. Quite impressed by the initial size of the rift and it is well decorated in places. The rift then drops down to a narrow slot where progress becomes a little more constricted but it looks good. We will return to carry out some rock engineering to ease further passage to whatever lies beyond.
20th December 2015: From Home Close Hole to the terminal choke at the end of Wigmore Swallet.
With Nick Hawkes, Claire Cohen and Sam Batstone.
Todays mission was to rig some aids to enable better access along the route into the terminal boulders at the end of Wigmore. I set off to rig the pitch while the others sorted out the required kit and followed me down. Had a few lighting problems but eventually managed to sort this out – lack of TLC and maintenance! An uneventful trip through the connection clearing some gravel on the way into Young Bloods, up and over the Generation Game and into the impressive Vindication Streamway. An aqueous climb down through Slime Rift and eventually the terminal boulders.
A clamber up a slippery slope using an in-situ rope, the final manoeuvre through the slot is not easy. Entered into a tiny chamber where I sorted out the ladders and rope to aid passage through the slot and down the next section. The route continued as a corkscrew climb down through boulders with a thick coating of mud through some barely body sized slots to regain the stream still in boulders but cleaner. Nick followed on while Claire and Sam waited at the rope climb, there is only room for two at this point. We had a look around and poked our noses into various spots moved some rocks before having a more concerted effort at stream level where a gap amongst boulders was noticed. It was then time to return to the others. Nick led up through the climb, a mistake on my part as he emptied his wellies all over the mud, the return up the corkscrew is a complete twat, but eventually was spat out through the slot at the top head first and sliding down the slippery slope – good job we had put a ladder there to halt progress in the boulders below.
A steady journey out of the cave, stashing the ladder and rope down Slime Rift up onto a ledge out of the water – this is an exhilarating climb! There are a number of precariously jammed boulders along the way particularly in Young Bloods and it is probably better not to spend too much time thinking about them. At the pitch the usual wait as the team climb the rope. Pitch de-rigged and out to tea, hot soup and sausage rolls – very much appreciated. Changed into dry grots and retired to the Queen Vic for the usual de-brief.
10th December: with Tom Chapman, Jake, Nick, Tav and Alex.
The Hallowe’en Team beyond the show cave in Wookey Hole Chamber 20.
The decorations caught us by surprise somewhat and were the subject of some amusement.
Geologically Wookey 20 is interesting being formed mostly along the unconformity between Carboniferous limestone and Triassic dolomitic conglomerate. There are a number of fine rock formations including rillenkarst (pictured below).
We spent a while exploring the main chamber beyond the scaffold walkway looking at the sump pools where the divers exited, up to the unconformity and other formations.
You’ll have to excuse the additional lighting of the image above.
We headed off to explore the rest of the cave accessible from Wookey 20 and we were pleasantly surprised by its quality an how much there was to it. A climb through an inclined passage of fine proportions with some good speleothems and interesting rock formations i.e. more rills, flutes and scalloping. At the end there is some considerable potential to extend the known cave and some side passages that would require some further attention. Another trip to properly assess some of the potential is planned in the not to distant future. An excellent couple of hours caving!
Got an invite by Sarah Payne to visit the recently accessed Tankard Mineshaft and offer my opinion on prospects and how best to proceed. Met up with Sarah and Duncan Simey at the Hunter’s and headed up the road to the field where the mineshaft is located, here we were joined by Tim Payne the farmer and landowner. The shaft is covered by a manhole lid and a tripod is currently in position.
The shaft is c.10m depth with a ginging for the initial c.3m leading to a muddy base with plenty of dead animal bones, apparently discarded lambs from many years ago. The miners have moved a quantity of rocks and stacked them in various nooks and cranny’s, very much like walls of ‘deads’ in active mines. There is a good number of loose rocks and the base of the ginging shows some signs of collapse, there is some requirement for consolidation before too much exploration proceeds.
The prospects, there is some space visible beyond some rather precarious perched boulders, where a rift appears to lead off the shaft, this is not clear at the moment and some clearance work in the future will allow a better assessment of the way ahead. There is the possibility that the ‘floor’ is not quite as solid as it might at first appear. I would suggest attaching to a rope when digging down, just to be on the safe side. Anecdotal evidence suggests that the mineshaft was once deeper.
The location of the mine shaft suggests that there might be some relationship to the notorious Tankard Hole that was closed a number of years ago due to it’s instability. It has been postulated that the shaft was an exploratory dig by miners searching for ore and terminated when open cave was encountered and this does seem a reasonable assumption at this time.
7th December 2015: A fine ditch excavated by yours truly on a site in North Somerset. The pottery recovered from the fills would suggest a Roman/Romano-British date. There’s quite a lot going on with cuts and re-cuts. The slot measures c.4m width, c.1m length and c.0.9m depth and took a couple of days to excavate. The underlying geology is Head – Clay, Silt, Sand and Gravel, these are Superficial Deposits formed during the Quaternary Period; these deposits, in turn overlie bedrock of Mercia Mudstone Group formed during the Triassic Period. Scale: 2 x 1 metre.
Connecting Home Close with Wigmore Swallet – A personal account.
With Nick Hawkes, Paul Brock, Sam Batstone, Claire Cohen, Pete Hellier, et. al.
Went back to clear the debris from the rock engineering work carried out on 20th September (see previous entry for that date) to find that it had worked rather well. Cleared away the loose debris much of which fell through the slot into the space below. Eventually was left with a massive loose flake that was teetering above the way forward, it took a while to persuade the flake to move and it crashed down into the space beyond. A c.3m climb down into a small chamber with a boulder floor and stream flowing over a cascade, hence “Roaring Waters”.
Survey of the crawl along to the dig (Roaring Waters) by Nick Hawkes, et. al.
Upstream the stream has been explored, continuing as hands and knees crawling before becoming too low. Downstream the way on was constricted by a lowering roof to almost stream level but there appeared to be more space beyond where Nick said he could see “something blue”. Surprisingly the stream was flowing along vertical bedding comprising a large slab of limestone between marl and conglomerate.
A return was made to enlarge the constriction and on the subsequent trip after clearing the debris this had created the “something blue” was seen to be a diver’s reel that had been left at the furthest extent reached of an inlet explored from Young Bloods passage in Wigmore Swallet. Rather frustratingly the reel could not be reached yet and the further use of chemical persuasion was required. During this phase of exploration surveying work was being carried out by the rest of the team.
On the next trip set about clearing the debris from the bang, then a gravel bank was encountered and removed, the dive reel was reached and the connection into Wigmore was made. The rest of the team were busy surveying the upstream passage and when they returned we made the first trip from HCH into Wigmore and Young Bloods passage, the first non-diver’s to see it and it was good! Progress was somewhat thwarted by rotten ladders and some dodgy hangers, there was some re-rigging required and that would have to be a job for another day.
The following trip was to carry out more surveying work and some gardening work to make the connection a little more comfortable. The connection passage is wet and low in places with a couple of squeezes thrown in, there is some easier passage as well.
The team returned to Young Bloods armed with drill and hangers, ladders and ropes ready to attempt the climb up into the Generation Game and the link to Vindication Streamway.
The climb up into Generation Game was not pleasant. I climbed onto a large slab of rock wedged diagonally across the passage, held up by not very much. Everything was coated in thick mud and it was all rather committing. I attached a ladder to a jammer and pushed it up as far as I could reach and using the ladder I completed the climb, I was mighty relieved to make it. I then re-hung the ladder on one of the better but still dodgy hangers for Paul to climb up and we then set about installing new stainless steel hangers and a new rope. We were then joined by the rest of the team and we all went through the Generation Game to the climb down into Vindication Streamway. While Paul and I put in some more hangers Nick went back to retrieve the ladder from the climb up from Young Bloods so that we could access the stream below. Vindication is a fine streamway of sizeable proportions and plenty of water and cascades including a deep section where a swim is possible if you feel so inclined. The trip ended at this point when another ladder was required to make the climb down Slime Rift. This section of stream passage is one of the finest on Mendip.
The following week we returned to complete the rigging, adding more hangers and stainless maillions, cutting away the old ropes and generally tidying up. While Paul and I were doing this Nick, Pete, Claire and Sam went ahead to tackle Slime Rift.
When we arrived at Slime Rift there was some confusion as Sam had seen Nick and Pete rig the ladder from a boulder only to find the ladder was no longer there. I climbed down the wet c.5m rift to enter a bigger rift where I could see the ladder had been hung down to re-enter the stream passage below, apparently Nick and Pete had returned to retrieve the ladder from it’s initial position. Paul joined me and new hangers were soon in place and we descended to the stream below. It was easier to use the ladder as a handline halfway down the rift and avoid the water. We met Nick and Pete on their way back from the end saying that more kit was needed as there were some slippery mud covered climbs ahead. Paul and I went to have a first tentative look at the boulder choke but didn’t really scrutinise it too much at this stage. That will be the next phase in this adventure – watch this space!
The connection from Home Close to Wigmore Swallet presented in Descent (No.274) as reported by Tony Audsley.
Popped down Templeton’s with Dave Morrison and John Hill (Eric Dunford on the surface) to discuss a plan of action for the future. Dave explained what he required and we formulated a strategy and will proceed starting Wednesday 30th September if all goes well.
