Hallowe'en Rift, Mendip Hills

Excursions [and other notes] involved in the exploration of Hallowe'en Rift; a cave, so far, formed within Triassic Dolomitic Conglomerate.

The exploration of Hallowe'en Rift was started in 1982 by Trevor Hughes with other members of the Bristol Exploration Club, their interest waned by the late 80s. During the early 1990's Vince Simmonds and other, mostly, local diggers were active at a number of locations within the cave, including the start of the dig to the 'east' side of the entrance with Graham Johnson in December 1991. This led to the discovery of An Unexpected Development in August 2018. The current phase of exploration was commenced in 2009, with the majority of the early work being carried out by Vince Simmonds and Alex Gee, now the regular team also includes Rob 'Tav' Taviner, Graham 'Jake' Johnson, Nick Hawkes, Jonathon Riley, Paul 'Brockers' Brock, Roz Simmonds, and Duncan Price. There has been occasional help from others including Phil Coles, Caroline Allen, Mike Willett, Mike Moxon, Matt Tuck, John 'Tangent' Williams, Pete Bolt, Bob Smith, Callum and Hazel Simmonds, and several appearances by that well-known antipodean, Ray Deasey.

There have been visits from some notable experts in their various fields including: Charlie Self, Andy Farrant, Christopher Smith, Derek Ford, Joyce Lundberg, Don MacFarlane, Marc Luetscher and Gina Moseley. All have added to a better understanding of Hallowe'en Rift.

With Jon, Jake, Nick, and Duncan

Good to see Jon back again. Four of us (Jon, Jake, Nick, and me) set-off from the farm, arrived at the cave, decided on an 80-bag total (20 bags per person) for the session and headed underground. Nick and Jake digging along the NE passage, me on the ledge, Jon at the entrance. A couple of bags had been filled and moved along the line when Duncan arrived (we didn’t make a readjustment in bags to filled quota for one reason or another). Duncan swapped places with Jon in the entrance (Jon went up to the surface) and soon the status quo was restored.

Things were progressing steadily when word came from the dig-face that a “hole” had opened – “rabbit-sized” with a draught. Work continued. Nick and Jake swapping places after each filling 20-bags. The filled bags were flowing along at a steady rate and no skip capsizes around the awkward bend. After 60-bags had been filled, Nick came up to the ledge so that I could do some digging. The “hole” at the top of a steep, awkward slope had been enlarged a bit and was looking very enticing. Work continued to expand the access upslope towards the “hole” and eventually it was large enough to wriggle through. This was made easier by Jake who had the foresight to get the short ladder stashed at the top of the pot to stand on. The “hole” led to a small space with abundant root growth and a partially sediment-filled phreatic tube, c.1m dia., trending c.NE. It’s not ‘Trick or Treat’ as expected (although it might lead quickly to it) but appears to be something in between. It might be worth trying to establish an aural connection between the top of the NE passage and the end of ‘Trick or Treat’ at sometime in the near future. It is clear that there is still plenty of digging to be done to open better access into the space and so gain more understanding of where things are going.

Unfortunately, the digging team will be a bit depleted during August as Jake, Duncan, and me, have other commitments to fulfil. Although I am sure that the rest of the team will be perfectly happy beavering away in the deep Soft South. Happy days!

With Jake, Brockers, Duncan, and Nick

Me and Jake down in the deep Soft South forging ahead along the NE passage, Brockers on the ledge, Duncan at the bottom of the entrance, Nick on the surface. Following the set quota of 20 bags per number of participants, a total of 100 bags were filled, hauled, and emptied. At the dig face the mornings progress was noticeable, some very tiny spaces at roof level were noted, these probably the result of sediment settlement over time but, interesting all the same.

Exited the cave to some very warm sunshine. It was not really a great surprise to find that Nick had not only hauled out the filled bags but had emptied them too. He did say the biting flies were not too much of an issue – probably too dry and hot for them.



9th July

No digging due to a number of factors including ailments, Priddy Folk Festival, and the need to dig a big hole to bury a goat.

With Brockers, Nick, Jake, and Duncan

Brockers and Nick digging so a regular supply of well-filled bags was to be expected. I was on the ledge catching the hauling bucket and transferring its load to the next skip to be hauled away by Duncan positioned at the bottom of the entrance. Jake was on the surface. 10 packs (c.100 bags) were dispatched to the bottom of the pot in the deep Soft South ready to be filled, rocks were left awaiting removal at a later date.

Later in the session a request was relayed to the diggers from Jake asking that the bags were not overfilled as it was raining and the haul rope becoming increasingly slippery.

When all the bags had been filled it was time to exit the cave and return to the surface to empty them. The stream of water flowing down the entrance was clear evidence of just how wet it had become. It was rather squalid as we emptied the bags.

Last job of the session, emptying the bags!


25th June

With Brockers and Jake

The last men standing apparently. Anyway, stock to the 20-bag/person quota and got on with it. Me, Jake, and Brockers, respectively, filled bags, cleared them away hauled them up to the ledge and dragged them along towards the entrance. Jake managed to eventually entice a large lump of calcite out of the dig-face and proceeded to roll it along the passage until he decided to reduce it to more manageable pieces with the sledge hammer. All bag quotas filled, rocks were left for another day, we moved the filled bags along to the entrance, hauled them out of the cave to empty the contents onto the spoil heap. A good session.

Disappointingly, the Hunter’s Lodge Inn was not open today due to people attending the Pilton pop show! Cycled up to the crossroads and kept going onwards to home.

Jon and Brockers digging down in the deep Soft South following the NE passage. I was on the ledge unloading the hauling bucket transferring the contents to the next skip to be hauled away by Tav at the bottom of the entrance. Jake and Nick were on the surface hauling out and emptying the filled bags. A busy session, plenty of banter, 100+ bags filled, hauled, and emptied plus several skip loads of stones. The skips going up and down the entrance now looking increasingly worse for wear and really need to be replaced.

A satisfying session. Refreshments were taken at the Hunter’s Lodge Inn.

No digging took place last weekend (4th June) I was in the Yorkshire Dales (BCRA CA SIG Field Meeting at Lower Winskill, Settle) and the team took advantage of the longer [Jubilee] bank holiday.

With Brockers, Jon, Jake, and Nick

Nick and Jake were today’s digging team down in the deep Soft South heading NE, back to two due to the lower numbers. Brockers on the ledge, Jon at the bottom of the entrance, leaving me on the surface. The skip was being loaded at a relentless rate – filled bags interspersed with the occasional load of rocks. There was no time to empty the bags. It was warm and humid, thankfully there was a breeze every now and then, but the flies were becoming increasingly annoying! About 100 filled bags plus several skip loads of rocks were removed and dispersed.

Filled bags are lined up waiting to be emptied!

A c.3-hour session at Hallowe’en Rift is a better overall workout than any gym…then there’s the cycle to and from the farm.

Refreshments (and a rest) at the Hunter’s Lodge Inn was very welcome.

With Brockers and Jon

A small team assembled at the cave today. At the entrance a brief discussion regarding digging strategy. It was decided that 60 bags were to be filled (20 each) then hauled out and emptied. So, we headed underground. At the bottom of the entrance, I collected 6 packs of bags (10 bags/pack) and headed down to the deep Soft South followed by Brockers and Jon, both, not wanting to be empty-handed, arrived with more bags. The digging continued at the end of the c.9m long NE passage. It all started according to plan, I filled my 20-bag quota, Brockers cleared away to Jon stashing the bags at the bottom of the pot. Brockers, of course. having to find something to occupy himself filled a few bonus bags while awaiting his turn. I swapped places with Brockers and following a chat with Jon went up onto the ledge to start getting some of the bags out of the pot and stashed ready to be moved further along the passage later.

Brockers filled his quota of 20 bags plus a ‘bonus’ pack and swapped places with Jon who proceeded to fill his 20 bags. Brockers came up to the ledge and I returned to the pot to haul filled bags up to him. Eventually, all quotas filled, the bags were moved out of the cave and emptied onto the spoil heap. The final count, 83 bags plus one rock. Below ground there is an increasing stockpile of rock awaiting removal and there were quite a few rocks added to that pile today.

A warm pedal up the Old Bristol Road in the sunshine and welcome refreshments in the Hunter’s Lodge Inn with the team. It had been a good and productive session.

Full strength team turn-out again this weekend. Jake, Jon, and Tav digging down in the deep Soft South going northeast, Brockers on the not so slippery ledge, Duncan hauling from the bottom of the entrance, leaving me and Nick on the surface.

A fine productive session, 142 bags were filled, hauled and emptied, plus a selection of rocks for the wall building stockpile.

Some of us went to the Hunter’s Lodge Inn for refreshments. Warm work pedalling up the Old Bristol Road (and Tyning’s Lane, of course).

The shed

With Nick, Duncan, Tav, Jake, Brockers, and Jon

The full team assembled today enabling three to go digging in the deep Soft South. Me, Duncan, and Nick took it in turns, on a 20-bag turnaround, to loosen sediment and fill bags, carry the filled bags along the NE passage, and haul the bags up to the ledge. Tav had taken a position on the higher ground to catch the bucket and transfer its load to the next skip to be hauled away by Jake, at the bottom of the entrance. The drying conditions underground meant that the skip did not slide along the passage freely and required a regular sprinkling of water, also, the skip needs replacing. Brockers and Jon were on the surface in the pleasantly warm sunshine, although probably being pestered by flies.

Today’s total, 120 bags filled, hauled, and emptied onto the spoil heap.

Refreshments were taken at the Hunter’s Lodge Inn where some rather random conversations took place.

I was on the not so slippery ledge, it’s drying up nicely now, emptying one skip and loading another to be hauled away by Duncan, who was in position at the bottom of the entrance. Jake and Tav were on the surface.

A good, steady, and productive session, 145 bags filled, hauled and emptied onto the spoil heap.

Refreshments at the Hunter’s Lodge Inn were welcomed. It was a warm pedal up the Old Bristol Road from the farm.

Jon and I alternated the tasks of hauling and emptying bags, adding any rocks to the various terrace walls, and generally enjoying the fine, sunny morning. It’s a lovely time of the year in the woods, fresh leaf growth, birds singing, butterflies but no flies…yet!

Over 100 bags filled and emptied, a few skip-loads of rocks. A good team effort.

Some of us went to the Hunter’s Lodge Inn for refreshments.

Saint George’s Day

With Brockers, Jon, Jake, Tav and Duncan (briefly) he only came for the beer! Later joined by Samuel and Rosie Mills (Wookey Ale) for the Hallowe’en Rift beer launch.

Got to the farm a little early and spent some time chatting to Mark (the farmer) until the team started to arrive in dribs and drabs.

At HR we decided to get on with some digging until the beer launch, me and Jon tidied up the loose spoil left by last weekend’s diggers, about 20 bags were filled. Jake was on the ledge, Tav at the bottom of the entrance, Brockers on the surface with Duncan. When Samuel and Rosie turned up, we all made our way to the surface, an executive directive issued by Brockers. Very generously, they had arrived with bacon sarnies and beer!

Left to right: Rosie, Samuel, Jon, Brockers, Tav, Jake, Duncan, I’m behind the camera!

Refreshments over it was time to introduce Samuel to the deep Soft South! As Brockers was on the surface today he lent some kit to Sam. Once down at the bottom of the pot in the deep Soft South, a can of beer was placed on a suitable rock and ceremoniously opened with a single, mighty blow from the sledgehammer – the beer had been launched! Photos and videos taken, a brief explanation of the dig and geomorphological processes evident it was time to return to the surface. A farewell to Samuel and Rosie, then returned to digging.

Samuel holds a can of Hallowe’en Rift down in the deep Soft South!

A further 50 or so bags were filled, several trip hazards left over from the week before were broken up and hauled out to the surface too. All in all, it had been an okay morning.

Further refreshment, for some, was partaken at the Hunter’s Lodge Inn.

Brockers and Phil digging down in the deep Soft South, Jon on the ledge (the skip from the pot has been rejuvenated), I was hauling from the bottom of the entrance and transferring the load to be pulled out of the cave by Nick. On the surface filled bags were emptied onto the spoil heap and other landscaping was carried out whenever there was a spare moment. Looking up from my seat I could see that the weather was pleasant. About 90 bags were added to the spoil heap and quite a lot of rocks too.

Refreshment was taken later at the Hunter’s Lodge Inn.

Also, on the surface, wall construction and landscaping activities were occurring. The weather was good for it too!

No-one kept a tally of bags shifted but it must have been in excess of 100.

Brockers bought Phil along today, normally, guests would get digging duties, but Phil declined the honour. However, Nick eagerly snapped up the opportunity as he had missed out on a couple of digging sessions due to work commitments. Nick was joined by Jake in the deep Soft South. Duncan was on the ledge, Phil occupied the corner spot, Jon at the bottom of the entrance leaving me and Brockers on the surface. After an early frost the weather was superb, it’s a sheltered spot at HR and warm in the spring sunshine. Brockers did all the hauling while I built another terrace wall and emptied the bags behind it. No-one kept a tally of bags, but it must have been in excess of 100 plus quite a lot of rocks.

About 100 bags were filled, hauled, and emptied along with several loads of rock being added to the wall building stockpile. The weather was glorious, but it was still surprisingly damp and soggy underground. The dimensions of the sediment choked passage being followed have not diminished.

The session started with Brockers fettling the hangers to which the pot pulley is attached, he then joined Jon to dig, fill bags and haul away the spoil. I was on the ledge, catching the bucket and transferring the load to the skip, Nick was at the entrance to haul the skip along. We had decided that with a smaller team to not have someone at the junction, with some care the skip could be pulled along, there were a few spills and the areas that required more attention noted. Jake was on the surface hauling the spoil away. 40 bags plus an assortment of rocks were moved out of the cave before activities were ceased and we all returned to the surface to meet our guests.

There’s a beer about to be marketed with the name “Halloween Rift” brewed by Wookey Ale. Trevor Hughes, who has shown no interest in HR for 35 years had the cheek to contact the brewers telling how he found the cave, etc. I also sent email to point out the current situation and who is actually active at the cave, adding a link to the blog. The upshot is the brewer’s came up to meet us at the cave, Trevor turned up too, with Kate (TH had been contacted by the brewer).

Socialising put a halt to the digging all that was left to do was empty the bags and secure the cave.

The new craft beer due to launch in April!


26th February

With Jon, Nick and Tav

A reduced team today due to whatever reasons, no matter.

The first task of the day was to replace the hauling rope on the pot pulley system in the deep Soft South. That done, me and Tav digging, rotating the filling of bags, and hauling up the bucket. Jon was on the ledge catching the bucket to un load the contents. Nick was at the junction and shuttling to and from the entrance where the spoil was temporarily stashed. In between loads Nick occupied himself breaking rocks with a hammer.

At the end of the session, 75 bags filled, hauled, and emptied onto the spoil heap plus about two dozen loads of rocks. A reasonably productive session.

With Tav, Duncan, Jake, Jon, Brockers, and Nick

Me and Tav on surface duties after digging last weekend, we alternated emptying bags, building a wall, and hauling. Duncan and Jake took up position at the bottom of the entrance and the junction, respectively. Brockers was in isolation on the ledge, leaving Jon and Nick to do the digging bit. This combination of digging team resulted in alternating batches of sensibly-filled bags and over enthusiastically-filled bags, the heavier bags were less welcomed at the hauling stage as the rope became increasingly claggy as the morning moved on. By the end of the session, 124 bags had been emptied onto the spoil heap, and about two dozen loads of rocks added to the terrace wall or the stockpile. The weather was more settled following Storm Eunice, although it was still breezy and there was the occasional squally shower.

The first task of the session was completed by the Technical Manager, Brockers installed a swivel on the pulley attached to the pot hauling system. Me and Tav were digging, alternating the filling of bags, and hauling the bucket up to Jon on the slippery ledge. Some adjustments were made to the hauling system to make operations a bit easier. Jake was at the junction (suffering from plantar fasciitis), Duncan at the bottom of the entrance (nursing a dodgy knee), Brockers and Nick were on the surface, they were later joined by Caroline. Between them the surface team hauled out 110 filled bags, redistributing the contents onto the spoil heap, rocks were added to another fine terrace wall on the upper level that was under construction.

New bags had been supplied to add to the c.100 we already had, it was going to be a busy session, especially so for the solo effort put in by the man at the top!

With regard the data logger…it’s probably better to read and fully understand the operating instruction before installing. Never mind, try again next week. Although I got a reading for today, 10.5OC, 98.5% RH.

Me and Jon digging down in the deep Soft South following the NE “passage”. My first task was to position a data logger to record temperature and relative humidity, for no other reason than I am interested. At start of session: 11OC, 84.6% RH. Meanwhile, Jon was filling bags. We alternated filling bags and hauling for the rest of the session. Brockers was on the ledge, Nick at the junction, Duncan was at the base of the entrance resting his sore knee the consequence of dry slope skiing. Jake on the surface hauling up the spoil, a task not made easier by a damp and claggy rope.

Jon filling bags!

Just over 100 bags were filled and emptied onto the spoil heap along with several loads of rocks. At the end of the session: 11OC, 94.6% RH was recorded, it was noticeably ‘steamy’ when I tried to take some photos of the SW facing section of the dig-face.

Jake and Duncan digging along the north-eastward trending tunnel at the bottom of the pot in the deep Soft South. Hauling the loaded skip was made easier with the liberal application of sand (from the layer at the base of the NW facing section). I was perched on the slippery ledge catching the loaded skip and transferring the load to Jon, sitting at the junction; Brockers was at the bottom of the entrance. Nick was on the surface hauling the spoil out of the cave, and he found time to empty the bags too. Top effort!

At the dig-face it was hard going, very compact and cemented fill requiring full use of the pickaxe to loosen the sediment. About 100 bags were filled (and emptied) plus quite a lot of rocks and fragmented calcite. A good, productive session. Refreshments taken at the Hunter’s Lodge Inn.

After digging last weekend, me and Jon were on the surface; Duncan was at the bottom of the entrance, resting his knee following a trip into Wookey 22 yesterday. Brockers and Nick were digging, this left Jake and Tav to occupy the ledge and the junction (I do not know who was where).

On the surface, Jon hauled up the steady procession of filled bags and, quite a lot of, rock. I emptied the bags and added the finishing touches to the final terrace wall on the south-side of the heap, generally tidying and levelling up the surface area. When I left at mid-day it was all looking neat and tidy.

An early finish for me to attend the BCRA Cave Science Symposium being held online (Zoom) this afternoon. These are the presentations that were due to be presented at Hulland Ward in Derbyshire last year (27th November 2021) but Storm Arwen put a stop to that event when it dumped a lot of snow resulting in power cuts and a lot of digging at the Orpheus CC hut! The presentations were varied, interesting and informative.

Survey updated by Duncan, annotated by Vince, 8th January 2022.

With Jon, Nick, Brockers, and Jake

Not the most inspiring of mornings, weatherwise that is, it was very wet. Thankfully, the worst of the rain had passed by!

Me and Jon were digging, at least we would be after clearing away a mound of spoil left from last weekend, apparently it must have been the result of a “collapse” or so someone (not that far away) tried to suggest. The left (north west) side of the passage has been cleaned back to expose rock, just need to do the same on the right (south east) side. The “dig-face” continues as a sediment filled tunnel, nearly 2m high x 1.5m wide. All very intriguing. The hauling rope has become impregnated with mud, and it was wet, very difficult to keep a grip and pill the loaded bucket up to the ledge. The bags were slightly reduced in weight to compensate.

Nick was catching the loaded bucket on the slippery ledge, Brockers was at the junction and Jake stashed the spoil at the entrance. When all the available bags were filled, we made our way out to the surface to empty the bags, there was one token stone. It was mucky on the surface and there were no votes for doing it all again.

Refreshments were well-earned and enjoyed at the Hunter’s Lodge Inn. One benefit from the inclement weather is that it keeps the grockles away!

First trip of the new year, many more will follow. Met Duncan at the farm, 09:30, plan was for Duncan to update the survey of the ‘pot’ in the deep Soft South. Quickly measured in a base line, then some dimensions for the pot and last night’s section line. All done just before the digging team arrived.

Duncan surveying the ‘pot’ in the deep Soft South

A brief discussion on the surface before heading underground. Jake and Brockers took on the digging duties, Duncan catching the bucket from the very slippery ledge, Jon at the junction, me at the entrance, Nick on the surface hauling out the spoil. Being on the surface was going to be the most difficult task of the day given the recent wet conditions. The hauling rope soon became caked in mud and not easy to grip firmly, the bags too were very claggy, making the rope even muddier. Suffice to say with Jake and Brockers digging bags and rock were moving through the cave at a good steady rate, no time to empty the bags. When all available bags were filled, all out to get them emptied.

Last night’s recorded section no longer exists, there are a lot of calcite fragments on the surface, much of it quite degraded.

Back at home, a lot of kit to wash and clean ready for the next trip!

Down in the ‘pot’ in the deep Soft South, at the current extent of the ‘passage’ heading in a north-easterly direction. Not digging as such but making a record of some interesting sediment deposits (photographs and scaled drawings, etc.) before they get dug away tomorrow. Also took some sand samples – want to see if they are wind- or water transported. It took quite a long time and could easily have spent longer at it.

A break from tradition as last weekend was disrupted by annual winter festivities, at least that nonsense is out of the way.

Going east from the pot before this digging session began

Down in the deep Soft South, Nick and I were digging, although Nick hauled the spoil away leaving me to get on with digging, he, of course, managed to do some digging as well. Jake was on the slippery ledge catching the bucket, there were several occasions when he though he might join us in the pot, good job he was attached to the safety line. Tav at the junction and Duncan at the entrance were appreciative of their comfy seats. Brockers on the surface hauled up the filled bags and rocks, even found time to empty the bags, a sterling effort.

It never ceases to amaze just how much spoil has been removed over the past 12 months or so!



Some sound advice for ramblers!

At the farm, Duncan stopped by briefly to drop of some fresh bags and to recount yesterday’s trip into Wookey Hole with Max. Sounded interesting.

Wasn’t too sure how many were going to turn up today as only Jon and Duncan replied to my earlier email. Eventually, a team of five assembled, changed, and walked up across the fields to the cave. A short discussion about ‘who was doing what’ ensued culminating in Jon and Brockers heading off to the deep Soft South to dig, Nick took up position on the ledge, I was at the junction and Jake, stacking stuff at the bottom of the entrance.

Jake gets sorted at the bottom of the entrance.

I went a short distance towards the Cold Gnarly North to retrieve a neoprene mat from ‘Duncan’s corner’ and collected a few more empty bags too. In was noted that there was plenty of water in the spa just ahead. The neoprene mat (now in two halves) was fashioned into comfy seats by upcycling old skips and bags foe me and Jake. All available bags, c.100, were filled, hauled, and stored in the entrance, the end of the digging activity signalled by the ceremonial filling of the ‘hessian’ bag. It was time to move up to the surface and clear out the cave, top up the spoil heap and add more stones to the terrace wall, thus creating more spoil space. It had been a very pleasant session.

Skip away!

With Nick, Duncan, Brockers, Jake, Jon, and Tav

Jake and Tav digging in the deep Soft South, Jon on the ledge, Brockers at the junction and Duncan at the bottom on the entrance, at least I think that was the order. Me and Nick were on the surface. We hauled bags and rocks up out of the cave, added more rocks to level up the terrace wall and create space for spoil, Nick dug some steps and, in general, it was a chilled-out session for us.

The terraced spoil heap.

93 filled bags were emptied onto the spoil heap and all rocks incorporated into the terrace walling. There was some question as to where the other pack of bags had gone as we were expecting 100+ to arrive on the surface. It turned out that someone had a comfy seat and was not prepared to offer it forward when the diggers had run out of empties!

An estimated value for the volume of the ‘pot’ in the Soft South.

Using the equation: V = πr2 h, and estimated values, 4 metres diameter (2m radius) and 5m height, an estimated volume = 62.83185m3  is calculated:

π = 3.14

3.14 x (2×2) x 5 = 62.83185

Assuming the density of limestone is about 2.6 – 2.7 tonnes/m3 and the density of clay soil about 2.0 – 2.3 tonnes/m3 and using the estimated volume of 62.83m3,  a range for the quantity of sediment removed can be deduced.

Using the lower density values above, for limestone 2.6 x 62.83 = 163.4 and for clay soil 2 x 62.83 = 125.7, a range between 125 tonnes and 163 tonnes of sediment has been removed from the pot in the Soft South since December 2020. This is likely to be an underestimation.

With Nick, Jake, Jon, and Brockers

Nick was left to do the digging, he seemed very pleased with the latest acquisition from a local car-boot, I hauled up the filled bags and sporadic dislodged rock or chunk of flowstone. Jake was catching the hauling bucket on the ledge, Jon at the junction with Brockers stacking everything in the entrance to be cleared out later in the morning.

Nick fills bags, the newly acquired long bar not far from his side!

The digging effort was concentrated at the eastern side of the pot (Soft South) where we are at least one metre into what appears to be a substantial choked “passage”. There is some interesting and intriguing sediment deposition ranging from fine compacted silt, loosely compacted medium to coarse sand, shattered calcite flowstone blocks, and cobbles/boulders of dolomitic conglomerate. Layering is clearly visible with evidence of high energy flow and static water, and ice damage.

All the bags filled including the hessian sack, it was time to clear out the cave and add some more spoil to the heap!

I was on a trip to the Peak District attend the BCRA Cave Science Symposium being held at Hulland Ward, near Ashbourne. Decided to stay at the Orpheus Caving Club hut. The passing of Storm Arwen sort of changed our plans and we spent nearly 5 hours digging snow off the track leading up the hill, back to the A515. The image below was snapped by Andy Farrant during a brief rest from digging!

However, a reduced team of stalwarts did turn-out at Hallowe’en Rift to continue the excavation in the Soft South. The following report was penned by Jon:

“Three of the team (Brockers, Jake and Jon) arrived in stormy conditions. The strong wind overnight had not completely died down and the rain had turned to sleet.

With only a small team, the approach taken to digging was different to usual. Sixty bags were sent underground and all three of the team went to the bottom and proceeded to dig.

Jon dug in the North-West corner where Nick’s boulder used to be. The apparent bedding closed down to the North; any development in that part of the pot can only be to the West (or down!).

Brockers and Jake dug under the arch in the North-East corner where Jake’s boulder used to be. This remains the obvious place to dig.

Having filled all sixty bags and replaced the rope on the bottom skip, hauling proceeded in a very efficient and industrious fashion. Spoil was initially stacked at the junction and then hauled to the surface in conditions of bright sunshine. The few rocks dug out today were left underground.

The team then retired to a local hostelry for well-earned refreshments.”

Earlier start for me, some large boulders to start reduction to more manageable pieces. Underground about 09:00am. The largest of the boulders was much thicker than expected and only achieved in trimming off the edges. So, concentrated my efforts on the slightly smaller rock and almost finished when Brockers turned up. Paul installed a safety rung at the edge of the ledge to provide a foothold for the bucket catcher.

The rest of the team had arrived, Jon joined me down in the pot, Brockers on the ledge, Jake at the junction with Nick temporarily storing the spoil at the bottom of the entrance.

As digging progressed the feature revealed last weekend on the east side of the pot became more interesting. An arched roof with remnants of fractured calcite formations showing up. It looks intriguing.

With Brockers, Jake, Nick, Jon, and Duncan

Met Brockers at the farm, 09:30, an early start to finish off installing the rungs in the pot, I had a new drill (18v) and a couple of boulders to break-up. The drill was okay and managed to reduce the rocks, or most of them to manageable pieces. The rung climb in and out of the pot done too. These tasks were ceased when the rest of the team arrived.

Jake and Nick digging, Jon on the ledge, I was at the junction, Duncan at the bottom of the entrance, Brockers up on the surface. Digging proceeded at a steady rate with a good flow of filled bags and rocks hauled out of the cave. There came a loud ‘yelp’ from below in the pot as an exceptionally large boulder decided it was time to make a bid for freedom narrowly missing Jake on the way. This boulder was eventually joined by another of equal proportion but in a more ‘controlled’ manner. They will require some effort to break-up. Now the boulders are out of the way, there appears to be an intriguing development to the east-side of the pot.

All available bags had been filled and hauled up to the surface, it was time to exit the cave and empty them and add the rocks to the wall.

Back at the farm, assistance was required to free my van from the field, an error of judgement parking in that spot!

With Brockers, Jake, Jon, and Nick

Met up with Brockers at 09:30 so that the installation of fixed rungs would be completed or, at least, well underway by the time the others arrived at the cave.

Brockers drills holes (14mm) for the rungs.

The lower- to mid-section rungs were placed enabling the ladder to be removed. Unfortunately, lack of battery power prevented the installation of the upper rungs, they will have to wait for another day. Jake, Jon, and Nick had arrived, so digging could commence.

Fixing the rung into place.

Me and Brockers were down in the pot filling bags and moving rocks (Brockers had a long wrestle with an especially large rock the was well jammed into a crevice). Jake was on the now rather slippery ledge, Nick was at the junction, Jon temporarily storing the spoil at the bottom of the entrance. When all the available bags were filled, and a pile of rocks accumulated it was time to clear out the cave and we all moved back.

It was disappointing to see that ‘someone’ had been up to his usual antics, the mindless and exceedingly pointless erosion of cave passage!

Just the one session again this weekend, did not bother going to the Hunter’s.

I arrived early so that I could photograph the sediment section, that I tidied and cleaned up last Saturday, before the digging activities got underway, and it became too steamy. Recorded a few video clips as well and was just about done as Jon and Nick arrived. After a brief discussion they climbed down into the pot to start digging and I went to ledge and clipped into the safety line. After some recent heavy rainfall, there was abundant and constant drips of water today and the potential for slippery conditions. Brockers came along the aqueous junction, Jake was at the bottom of the entrance. Digging began in earnest and the flow of filled bags (and some rocks) out to the entrance progressed at a steady rate. When all the bags available had been filled, hauled, and temporarily stacked at the entrance it was time to go and clear out the spoil.

All bags pulled out, emptied, and hung up on the line, the rocks added to the wall, it was decided that was enough for today and we returned to the farm. Just for a change, we made our way up the hill to the Hunter’s Lodge Inn for refreshments.

Solo

No-one else showed up, no matter. Spent the morning squaring and repairing the reference section, very peaceful it was too. Took my packed lunch underground with me and enjoyed my break sat on the ledge pondering the sediment layering I could see before me. Took the time to tidy up a couple of other things that were looking a bit scruffy too. Unfortunately, when it came to making a digital record my camera battery was flat, which was more than a bit annoying.

16th October 2021

Took a break from digging and decided on a bike ride, Devon Coast to Coast. Set off from Ilfracombe to Plymouth along National Cycle Network (NCN) route 27. Got to Plymouth, turned around and cycled back to Ilfracombe. 310km, 3300m ascent, 21hrs 50mins ride time. There were a lot of hills!

9th October 2021

With Brockers, Jake, Jon, Nick, Duncan, and Tav

The day started with a positive vibe. Underground by 09:15 and set about reducing the boulders in the deep Soft South to more manageable pieces. I was soon joined by Brockers who installed a backup to the pulley anchor. The boulders broken up, the backup installed, Brockers decided to head out to the surface to fetch some empty bags so that we could start clearing up the loose debris. He was absent for quite some time having met the later arrivals.

Next to appear in the deep Soft South was Duncan who was adamant that he was digging and joined me in the pot. Tav showed up and took a position on the ledge, the loose rocks were hauled up followed by the bags that Duncan had been filling. He thought the ‘cut-off’ cone was very useful for filling the bags with sand. At c.12:30 we decided to break for lunch as is the norm.

I spent the afternoon on the surface with Jake, he hauled the spoil out of the cave, while I emptied bags and added rocks to the terrace wall. It was very pleasant in the unseasonably warm sunshine. Unfortunately, the positive vibes were not going to last. Earlier, and mistakenly in hindsight, I had agreed to split a small boulder on the ledge that jutted out from my reference section. I had pointed out that the boulder formed an integral and important part of the section and should not be completely removed. The rock was split, and I made certain that the remaining portion was secure and tidy. I was very pissed off (and still am) when I recognised the last rock to come to the surface as the very rock I had asked not to be removed, the reference section will now be prone to erosion/collapse and I will need to spend more time on sorting it out!
