Mike Kushy, solo trip. A cold draught could be felt from the first climb down after Pocket Watch.  Went to Tooth Dig and moved the rocks back from the small chamber before the corner to the bottom of the climb, then moved forward and moved the stuff from the corner back into the small chamber. Then moved forward again and broke up some more rock in the floor and cleared any loose stuff out of the tunnel back to the corner. Removed some large blocks from the floor going into the undercut and made smaller then sent back to the corner. Filled up 6 small buckets of sand and mud. Draught was stronger from straight ahead today. Dug a little along the strike line and found more sopping red mud, there's a round hole in the ceiling all clean washed with water dripping out of it, must be where the worms came from? The ceiling has lots of phreatic remnant and seems to be rising up. Finished off by moving some stuff in the corner back to the smaller chamber, lots of clearing back up cave to do but mainly good sized rock so won't take too long. 3 1/2 hours. Mike.

Mike Kushy, solo trip. Took in 3 batteries. Cleared the build up of spoil at the corner back to the little chamber, then set to work on the corner boulder some more and making space. There's now enough for a comfortable seating area, lots of rock to clear in the little chamber before the corner. After using up just over 2 batteries I went to have a look at the end. Managed to split and move a very large rock right in the middle of the floor and another one behind that has been moved further back. These will need breaking down even more but the last battery gave up. There's now an impressive space forming in the tunnel and it was possible to turn round where the junction is. A little draught test proved that straight ahead and the undercut were draughting outwards (towards the corner) with the undercut draught seeming to be the stronger. I then cleared some mud back and had a little poke at the mud just under the white vertical calcite line into the undercut where the solutional pocket is. The bedding here is undercutting yet again and a noticeable change in draught happened whilst prodding, also things became a lot colder. There was slimy red mud ahead and a couple of earthworms. All very exciting stuff. A team of 5 will be needed to dig and clear right back, although it could be staged with even 2 people, but hard work. 5 hours, Mike.

Wednesday 29th March 2023

Sam Hill, Mike Kushy and Andy Thonpson. Tooth Dig. Andy went in front to downsize boulders from last session. MK and SH cleared stuff back and opened up the approach some more. Outward draught today (extracted from Logbook - MK - pending full write up from SH).

Saturday 18th March 2023

Mike Kushy and Andy Thompson. Got to the dig site around 11.45. We cleared back the debris from the last session, then MK took some higher up cave whilst AT went forwards and set to work on the annoying boulder. MK then moved forward and cleared back from the corner and also managed to remove some more from the corner block. Now being able to sit in the corner MK then took drag trays from AT until the annoying boulder was reduced enough to progress forwards. MK then moved forwards again and cleared around AT as he pushed forwards and dug the floor out along the tunnel. Right at the end of the session enough was cleared going into the void to push through completely and get a better view, the parallel tunnel was not as long as it initially looks and pinches out at the end. The phreatic bit that cuts through the bedding still looks interesting. Digging at the easiest spot in the floor is the best way forwards here next perhaps? (maybe before the corner), or we can work along the original tunnel to clear the boulders at the end. The draught was still coming from the end of the tunnel. Lots of rocks stacked everywhere and mud to clear out next time. Just over 4 hours. Mike.

Sunday 12th March 2023

Mike Kushy solo trip. Got to the dig about 10.30. The perimeter gate at the surface was wide open and I spent ten minutes ushering a few sheep out of the pen, the steps were covered in droppings making a smelly entrance. Got to Tooth Dig about 11, set up my music and started breaking up the rock at the corner. Reckon 50% of what was there is now in pieces ready to be cleared. I've taken a fair bit further back already, some stuff may want reducing more with a hammer. The block could be taken right out but I think it will be okay at the height it's at now with some levelling out.  With all batteries used I moved forward to dig out some more of the undercut into the void. With helmet off I managed to squeeze through up to my waist, into another layer of bedding. Off to the left looks the same as what we were in apart from no boulders at the end. The mud seems to slope away at the end, easily caveable if the floor is dug out more at the squeeze. Moving some more rocks and mud allowed a view to the right and straight on. Phreatic action from the right leads to a solutional pocket dead ahead, cutting through the bedded ceiling with an inch thick vertical line of calcite through the rock..the phreatic element seems to end here, perhaps a pot? Good draught coming from the left. The annoying rock in the floor at the start of the tunnel passage wants reducing or removing. The small crowbar, big crowbar and big hammer/chisel are near the annoying rock in the floor. The small hammer and pf set is on the approach to Tooth Dig on the left. Should be an interesting session for whoever is in there next, may want some horizontal drag buckets (just small ones and a small length of rope). 4 1/2 hours. Mike.

Thursday 9th March 2023

Andrew Thompson and Mike Wise. We hammered and P&Fd for 2 hours and chipped off a few bits here and there. We did bring back and neatly stack a load of rock from beyond the tiresome rock though and Andy went off and took some photos. Mike Wise.

A late start after work saw us enter the cave at 4.30. Mike first attempted to find his way through Tooth Squeeze but after deciding against it we switched positions and attacked the rock in the floor from both ends. Unfortunately it got the better of us and refused to succumb to our frantic hammering. We decided our efforts would be better spent taking some photos of the prospects in the sharp end and then doing some house keeping beyond the squeeze, as rather a lot of broken rock had been stacked next to the squeeze. I am please to say this has made a bit more space for next session. 3 hours A Thompson.

John Cooper and Andrew Thompson. Tooth Dig. Plug and feather work on the left-hand wall just before the boulder Mike wants splitting. Trying to make more room to work but it doesn’t react very well to this approach. Andy had a look at the end and was suitably impressed by the choices. 2½ hours. John Cooper

Sunday 5th March 2023

Mike Kushy, solo trip. Got to Tooth Dig at 11am armed with 3 batteries. Started on opening up the corner some more, one battery spent. Then feet first to the 2 blocks in the floor mentioned last time. Another battery spent removing one and making another considerably smaller, also worked on making the whole area more spacious. Lots of loose rock spoil in this area that needs clearing. Then went back to the corner for a rest and to retrieve the last battery. Decided this time to go head first all the way. Made it to the very end of the horizontal passage and had a better view than before, a narrow stand up rift at the end allowed me to get up into and with some stuff moved and some contortion I managed to turn around. The end here should be fairly easy to dig once we clear a safe exit. On the way out a little play into the void on the left side, unfortunately there's a large block in the floor spanning the whole length of the void only allowing a gap of about 4 inches...good draught again and very dry ground. The space beyond looks very intriguing, but the floor is going to have to be dug right out to see what we're dealing with. Some more space made on the way out, then back to the corner to continue opening that up some more. The large block on the corner is now split in two and would need to come out completely to allow digging the mud floor in the horizontal passage ahead. 4 1/2 tiring hours. Mike.

Mike Kushy and Mike Wise.

Started at 11am. Took 2 drills and 5 batteries into Tooth Dig to continue from the 2 Andy's work yesterday. Mike Wise started at the Tooth Dig whilst MK moved the spoil from yesterday higher up. Then MK set to work on Courtenay's boulder whilst MW was busy. After a short while we swapped places. Some rocks were pulled out from higher up allowing MK to enter the ongoing passage feet first, with a bit a of contortion. Tight going, even tighter over 2 rocks in the floor. A long triangular tunnel about 4-5 m long can be seen with a boulder collapse at the far end (potentially the other end of cement dig, and probably close enough for a light connection?). Half way along this tunnel the bedded ceiling has black voids undercutting the ceiling with a view of what looks a sizeable space, the draught was most prominent from here. Tried to dig the mud floor out a little, but unsure whether I was undermining blocks above without much room for an escape. On the way out some edges were hammered off and the blocks in the floor were reduced so should be easier and safer to go in head first next time and hopefully get into the void. Some more work can be done opening up the corner to get into the new passage. On exit MW had done the job of getting rid of Courtenay's boulder, allowing a crawl into a stand up chamber. No ways on but if we open up a way in higher up there's alot of room for spoil to go into. Both drills spent we went to cement dig to cement some more. 4 1/2 hours. Mike K.

Tooth Dig got a visit first with 2 drills, 5 batteries and a set of P+F. A few bits and pieces were finally knocked off some rocks blocking the way into the "passage" seen yesterday by the 2 Andys. Kushy got in feet first for about 6m into a small space in boulders. Rocks are very resistant to P+F!

The block at floor level mentioned in the report from 18 February was reduced to floor level and the approach was opened out. There is a small chamber on the other side floored with sand and cobbles with 2 places to stand up. The roof is made of the boulders beside the drop down and lights can be seen. Water was running down the "back" wall.

Having run out of battery power and abandoning a P+F stuck in a boulder we decamped to the Cement Dig. 2 mixes of cement were made and applied and the filled buckets at the bottom were emptied. Time digging 4 1/2 hours. Mike Wise.

Saturday 25th February 2023

Andy Morse and Andy Thompson

We arrived at Tooth Dig for 11am and quickly got to work. Very gingerly I removed a large block from the ceiling of the dig, squealing a little bit each time I hit the plug and feathers. This block was about twice the size of a microwave and directly above my legs so I was very glad to get it out without injury. Once this was removed I could work my way into the gap created, enough to see a very interesting looking continuation to the passage. Very excited to see where it leads over the coming month. We returned to the surface at 3pm. 4 hours A Thompson.

The Tale of the Tooth. Andy Thompson, finder of the tooth, had subsequently prepared the tooth into an identifiable condition. The tooth was able to then be confirmed as formerly belonging to a Woolly Rhinoceros (Coelodonta antiquitatis) possibly strolling around some 40,000 years ago. Andy Thompson and Andy Morse and myself (Tuska) met with Richard the landowner, who to say the least, was excited and shared with us his delight and interest in such a find. Richard welcomed the fact we would leave the tooth in his care and is happy for the tooth to go for more tests as needed and happy also to share the tooth with those wishing to see it. Hoping, I believe, for more similar finds that we all might better understand the Mendip environment at the time 'Fang' the Rhino roamed. All to play for. Tuska.

Saturday 18th February 2023

Mike Kushy, Courtenay James and Monica Bollani. Took in 2 drills and a Daren drum of cement. CJ and MB went to dig at Tooth Dig whilst MK went to the cemented dig. I carried on work enlarging the bottom, a strong acoustic connection with the others in Tooth Dig, estimate about 15m apart and probably at the same depth...but need to survey both digs. Some cement work will be needed at the sharp end to remove larger rocks in the ceiling, which will then allow access into the 'chamber' ahead. With all buckets filled and batteries used and no sign of the others I went to join them. 2 1/2 hours.

The other site is much more spacious since I was last there, a good draught. My feeling is the dig is going to force digging downwards at this point. Courtenay had been working on removing a large boulder at floor level opposite the squeeze into the dig. A good view beyond the Boulder can be seen with a floor strewn with black cobbles, also a very good draught emanating from here. 4 1/2 hours in all. The full tub of cement is in a red bag part way down the bedding and there's 2 and a bit half bags of sand (enough for a cementing session). Mike.

Sunday 12th February 2023

Mike Kushy, Andy Thompson and Frank Tully. Took in 2 x 1/2 bags of sand and a drill. Andy and Frank went to recent dig at the Boulder Rift dig, now referred to as the 'Tooth Dig'. Mike went to the cemented dig. Some more space made in the small boulder chamber, filled up 7 small buckets of spoil. Was able to squeeze into the horizontal part. A view onto what looks like a chamber with a solid wall, all clean washed and where the strongest draught comes from. Should be able to chip off the boulders either side to get into it, but it may take a few more sessions yet. Andy and Frank joined me about 2ish and the buckets were cleared up cave, one more load of 6 small buckets were filled and lifted up also. Ended the session with some cementing, whilst Frank and Andy opened up the top rope area to make hauling easier. 2 and a bit half bags of sand and no cement at dig site  Not sure how long, est' 4 1/2 hours. Mike.

Frank Tully, Andrew Thompson. We arrived at the dig for 11.30 and Frank took the first shift removing the floor to create some more space in the Boulder Chamber dig. After many buckets had been passed out, and Frank's legs had gone dead from the awkward position, I moved in to start removing the mud going forward. We managed to gain another foot or so. Amongst the spoil that was removed, we found a tooth. It is believed to belong to a Woolly Rhinoceros and will see the dig rechristened "Tooth Dig". Once we had both spent all of our energy and had a little play with the crowbar, we backed off to help Mike remove his spoil and mix him some cement. 3 hours. A Thompson.

Sunday 5th February 2023

Mike Kushy, Andy Thompson and Tim Rose. Took in sand, cement and 2 drills. Andy and Tim went to dig at the Boulder Rift dig, Mike went to the cemented dig. I opened up the dig face a little more and managed to pull the obstructive Boulder out of the floor. There's a big calcite blockage further down which I've started to remove some of but a lot more will come out. Tim and Andy joined me about 13.30 and clatch was removed from the very bottom, some interesting holes appearing in the floor. We finished off with a cementing session. Dry and bright day outside and a very good druaght at the dig. Note: I could smell Andy smoking in the other dig and the smell was coming from the floor in the dig I was in. There's half a Daren drum of cement and 2 x 1/2 bags of sand. 4 hours. Mike.

We met at Upper Pitts on Sunday morning for an hour of faffing around, drinking tea and discussing how tortoises go around knobbing each other. Monica & Courtenay tried their best to convince me to go to a proper cave with them but for some reason I honoured my promise to assist Mike in his Rabbit Hole. We headed over to the cave about 11am after we'd cleared up the important business of deciding what length a fossilised sperm whale phallus would be. The last time I saw Mike's hole it was just a hole. Now it's a certified, fully fenced off ring piece. Between the three of us we carted a load of sand and drill into the cave. I thought the general idea of a dig was to remove spoil from the cave, not take it in. Once through the initial passage and maze of gaps in boulders an impressive 45°  bedding plane is entered. Quite a bit of stal. and plenty of interesting formations. Mike sent Andy and I off through some more gaps in boulders to continue one of the two current dig sites, this one is found at the lowest point in the boulder rift. Andy did all the hard work removing a few rocks and plenty of clatch which I lost into various gaps in the boulders. The way on appeared to be horizontal. Meanwhile I took the drill to a few boulders on the approach to make life easier. One boulder in particular was proper fucking me off! Definitely a draft emanating from somewhere in that area and the whole time we could hear Mike drilling in the other dig. I'm certainly not qualified to comment but my gut feeling is that this dig will just follow the bedding and appear in the wall of the main chamber. I think I'd head down rather than horizontal if anything, but that looks a lot of effort. After sufficient punishment Andy and I headed to Mike's hole in the floor. This looked like a much more promising site to me. We helped Mike haul and lose a load of spoil from the bottom of the dig. Andy then whipped up a tray of sloppy and Mike smeared Andy's sloppy all over the walls before cleaning himself off on the curtains. All spent, we made a hasty exit and got back to the car at 15:30. Great to see the place and I look forward to stomping down a mile of clean washed streamway once it's found. Meanwhile I'll stick to Portland Boulder bashing. Tim.

On Sunday Tim and I left Mike at the cement dig to go and take a further look at the Boulder Rift dig. I removed a large boulder from the floor and with Tim's help managed to remove this from the dig. After creating a little more space I was able to get headfirst into the continuation. A strong draught could be felt and despite Tim's hesitance I believe it to be worth pushing. The next task will be removing the floor in the chamber we have created, to give us the space we need to dig going forwards. 3 hours. AT

Sunday 29th January 2023

Mike Kushy, John Cooper and Courtenay James. I left Courtenay and John to dismantle the obtrusive rock at the Boulder Rift dig, this took them about an hour and a half. Meanwhile I worked on opening up the cemented dig in the main bedding some more, also managed to clear out some rock from the on going area. When JC and CJ arrived we cleared the rock built up from plug and feathering and some clatch. The session was ended with some more cement work on the walls higher up. There's still an annoying bit of rock low down which needs coming out to allow further clearing ahead. 3 1/2 hours. Mike.

Sunday 22nd January 2023

 

Before

Mike Kushy. Solo trip to work on the cemented dig at the bottom of the main bedding. Plug and feathering the right hand hole, made it big enough to get into. Need to open up the slope on the floor a bit more which won't take long. Head first a view off to the right for a few metres, a small hole down to the left, draughting very well, appeared. A flowstone wall ahead, all feels very safe. Broke my 14mm drill bit and didn't have a spare so had to improvise with a 10mm and what I had left of the 14mm. Will need a team of at least 3 next time to pull the clatch and rocks out. 5 hours, Mike.

Saturday 7th January 2023

Mike Kushy, Andy Thompson and Courtenay James. Carried the rest of the bags left throughout the cave down to the Bedding Dig. Cleared out a lot of clatch that had washed in. You can now see the holes in the floor more clearly again. Looking down the pit, the hole on the right has a good view to a stal'd up solid wall which is concave with nodules on it and some nice formations. Good draught when you stick your head in too. There's a huge slab like block across the floor which I think has dropped from above (4m or so). I believe this could be the cause of the blockage. With some cementing done off this it should be possible to plug and feather edges off it and some of the right hand side to get in and clear the rest of the clatch and some bigger rocks. When we're into the next bit a lot more work cementing will need to be done, but for now it's workable and a decent size to allow progress forwards. After this we went to the most recent dig in the Boulder Rift. Good progress was made for an hour or so clearing cobbles and grit back, it's a decent size in there now and there's a lot more to come out, buckets left on site. At the end of this session a big block was moved that now blocks the way into the dig, this will need to be broken up to allow access again, but it will make the whole dig much more comfortable. This block will probably take a few hours to break up. 5 hours. Mike.

Monday 2nd January 2023

Mike Kushy, Samuel Hill and Frank Tully. We took in a lot of materials, 6 tackles sacks of sand, 2 tackle sacks of cement and 2 bags with drills. With hopes of getting into the new passage seen last time we set to work at the most recent dig site. The plan was to open up the approach to bring bigger rocks out, we soon gave up on this realising it's a big job and decided to head further down and squirrel on with the hope of a 'big breakthrough'. Frank joined us at this point. Capping and pfs we managed to make a hole big enough to squeeze into the next bit, that wasn't 2m high but more like 2ft, got the width right at about 5m though. Eastwater Lower Traverse type passage, and 'proper cave' with a small streamway. The water hits a sandy cobble filled floor and heads left (looking down), digging here will require opening up the squeeze, which in turn will require opening up the approach to get large rocks out. There's also a couple of fluted rock paths heading back up into the ceiling, but just slightly too tight to get up into. MK on the way out of the new bit decided to go check out the other pit, it was then decided efforts for the day would be better spent on the bottom of our original Boulder Rift dig. Some corners were taken off and we managed to get a body length in, boulders in the ceiling again (clean washed) with an easy diggable floor full of mud and sandstone cobbles...interesting site with a much more pronounced draught! On the way out looking up to the left you can see a hole with water trickling out of it, I predict this is the other side of the chamber we broke into earlier...the survey should confirm this once done.

We then finished off by cementing at the bedding chamber dig. Really happy to start breaking up rocks in the floor here next session and there's quite alot of clatch to come out. 1 half bag of sand and a 1/3 of a half bag at the bottom, quarter Daren drum of cement. There's 2 tackle sacks of sand left in the 4th chamber from the entrance plus a tackle sack of sand and a tackle sack of cement left in the first chamber (plenty enough for the next session). 6 hours in total. Mike.
