A fine and productive dig was had today, me and Tommy were accompanied by prestigious sand digger Rostam Namaghi.

Anyways, we headed in, and started moving stuff. Met some folks from Rubber Ducks on the way in, and some other folks from the YSS. A good day for P8!

Once in the dig, we dumped the sandbags that had been kindly given to us by Nick Williams this morning (will buy him a pint at some point!) And proceeded to get digging!

Whilst the previous pictures show the scaffold at my nipple height, it is now above the shoulder. Below the scaffold the dig is getting larger and could comfortably fit two people. Tommy says the dig is still trending horizontally downwards.

The dig will now need more scaffold to split the pot and start a wall up the middle, as we have run out of scaffing space.

After taking out lots of spoil over 4 hours, we each payed our respects to the Eavis shrine and left the cave

Andy Eavis has a shrine down there? Well, it was his first ever cave...
The end is where we start....

It's a shrine to the whole dynasty

P8 is exactly due west of my window, so I can pay my respects every morning from here.

As long as I am left out of it - I am only an Eavis by marriage. I am far to punctual to be a real Eavis ;)

A team of 3 Backhoe Buccaneers were down P8 last night, myself, Olly, and Jack.

We agreed to meet after work, Jack's day had run over slightly, but Olly and I mitigated the delay by removing the rear seat from his 2CV, sticking some tunes on and basking in the glorious spring sunshine to pass the time.

Now changed and through the fields, Jack sped off ahead to make it from entrance to sump in a record 5 minutes, myself and Olly were there in around 10. Up into the dig and we began.

We began with the same system as last time; man 1 quarter filling a bag, passing it out to man 2, who passes it up to man 3, man 3 then consolidates it into a larger bag on the pile. Rubbish! We then remembered the reason for the scaff and bags was to enable a 2-person team to dig more efficiently, with 3 of us there it made more sense to haul out to the top of the pot and stack/tip above. Thus, no more scaff is yet required if we can keep a team together, increasing bag stocks wouldn't hurt though either way!

Once the percolation slurry is cleared from the dig face, progress becomes much quicker. We seem to have broken through a layer of clay which wouldn't have been helping drainage much.

With some 25 kibbles removed, we have now driven a trench down into the dig, meaning we are digging forwards, rather than downwards. At last! There are still some larger boulders in place acting as trench wall, for now if we don't stare at them too hard they'll stay put. We won't be able to lift them out of the dig without resorting to destructive methods, though one lay directly ahead to tackle.

After some scraping and prodding, and the smaller boulder reft from its earthen captivity, the session culminated in being able to stick my arm forwards above the face and feel some calcite coming down from the roof. Intriguing...

We made it out in good time, however slightly slower moving uphill. A quick stop off at the Wanted to see Nick and the Bull Pit team, we also found a troop of SUSSites in there for a brief natter. However, the hour was late and it was time for bed. By the time I was fed and the soil removed from under my finger nails it was about 12:30/1am.

All in all a great session, we're going prodding in another location next week to allow the air to refresh itself a little in Christmas Aven, it wasn't an issue, but we were aware of a slight change as the session went on, it's not draughting yet!

Thanks for the report - sounds like the dig is progressing well

A team of 4 went in for a double whammy of project productivity on Wednesday evening.

Firstly we shifted all of the large green digging trays and assorted detritus of Ben Bentham's from the entrance to the backs of our cars, where they remain... To the best of my knowledge that now means Ben's dig is free of litter and Jack's "Trays for Days" cleanup project complete (pending disposal arrangements). I'll leave it to him to write up in full, but it was quite the unique bit of resistance training lashing 6 trays at a time each to the backs of our harnesses and dragging them across the fields.

We then jogged down to our Christmas Aven dig with the plan of shifting a couple of large boulders.
Hopping down into the dig we found the previous trench to be relatively intact but full like a bath tub.

After bailing the water down to make it fractionally more comfortable, SUSS's aspirant technician Olly volunteered to cap the blocks I had excavated, they were even bigger than previously anticipated. He made light work of this over the next 45 minutes, and we shifted the rubble out above.

I then went in to have a look at the way on, and made a mess of the trench as it succumbed to the lapping water as I dug a little, I can blame Olly a bit too.

It should be noted that Jack only had one welly, and was starting to get cold from lack of activity at this point, and with this being SUSS fresher Ben's first digging session, he wasn't allowed to dig, but next time he'll be thrown into the hole to show us his stuff.

I'm estimating a nominal 30m of digging until breakthrough, based on the angle of the passage leading to the dig and the height differential between the dig floor (not passage floor as we haven't hit it yet) and the assumed silt level from the Eldon and pre-Eldon days when they started this dig, but who knows...

Now to overthink things slightly: I've attached a draughtsman's representation of the dig, on the left as we know it, middle and right two possible scenarios.

With a small piece of calcite found during the previous session I'm wondering about its formation.
In scenario A, with a shallow roof, I would expect water to drip away before reaching the passage end, the hopeful scenario B could mean steeper passage allowing a more stable drip flow. Is the logic sound? Or is it just a small crack above letting water through perhaps? We'll know soon enough anyway.

 30m??  :o :o :o :o

You'll have to be leaving tributes to bring that number down.  :bow: :bow:  :bow: :bow:

are you sure that isn't 3.0m or 0.3m, you forgot the decimal point ;)

Unfortunately yes, but that's based on a hell of a lot of uncertainties.
I hope it's less...

SUSS will always be around to dig it, even if it takes until the 80th.

Your 80th. Wishing your life away there, we'll have to get you an armchair too.
 But it'll have to have one of those airplane meal trays and put it on a telescopic arm to enable you to dig.

I think he meant suss 80th, which is in 25 ish years time and is a reasonable expectation of how long we will be digging in Derbyshire :p

Alpine climbers/mountaineers peak in their late 30's - early 40's, cave diggers peak at 50+.

That's true enough. You get to lie down more when you're digging.

Nah, but notice your buckets still have not moved from the entrance.


Just a quick potter, Louise M wanted photos on P1 and we found ourselves in Towd mans rift last trip, but didn't find the side passage that leads to the stonking crawl passage and the fine aven which looks like it's ready for WWI again  :tease:


Do you hide behind the sandbags when you're setting caps off.  :beer2:

I'm planning to get back in there now the Summer Radon Scare is over.

I hope you approved of our scaffolding efforts.

My plan eventually is to rebeautify that aven and tape it once we break through and the route becomes a main traffic route on the Gautries-P8 through trip

I saw some scaffold at the bottom, but couldn't be bothered to take a closer look at some mud smeared bits of metal.

You're so "over" digging, aren't you?  :lol:

Nah, your dig looks like hard work. I've got ASV (as named by SUSS).
 Tis a good hole to go in and out of.

Had a good day last week, where I made a few applications in the morning, then left my mobile in the quarry, took two calls about jobs while in caving kit. :)


I should get a Bluetooth headset, then I wouldn't need to leave the dig to take the calls.
