Project: opening windle and rush mine to hopeful P8 sump 6 connection

Alastair: Loving the enthusiasm, and the two threads you've started. (y)

Digging: I can't commit to regular/weekly digging on this particular project - as I'm currently digging elsewhere. But, I should get chance now and then. Are you looking at evening digging, or weekends, etc?

Could someone post a survey of the quarry (and vicinity?) - with the proposed dig site(s) with the P8 survey overlaid? It'd be good for people to speculate - might throw up some other ideas if people can see it.

Red Dot: Entrance to P8, 100% accurate
Black Dot: Sump 6, data collated from 3 different surveys. Infer from that what you will. It's heading roughly EESE
Blue Dot: End of eldon end vein, by sight from the map in the PDHMS link. Heading west.

AR, black clouds forecast all day on friday but only rain till 11am. Then a rest with no rain till it starts up again at 3pm.

Meet at 11am to have a look? no digging yet. Although i may inspect a few rocks and throw them to oneside, to see err how heavy they are? And whether they bounce?

Alastair, Big Jim and I had a mooch around the quarry today, we didn't go onto the bench due to someone forgetting to bring rope as well as ladder  :-[ but we could see what looks to be the location of the engine shaft further along the bench from Sidetrack. We found the site of a probable climbing shaft further west on the rake that may repay excavation, not to mention much potential in Petras and the rifts to the west.

It was also a fine nature ramble, with newts in the pond, various birds on the faces, and a lizard trying to bask on the rocks!

On Google Earth ,of Eldon Quarry if you scroll back over the older images ,some interesting  holes appear which
in latter pictures are not there . Just to the left of the pond in the Eastern end is what appears to be a large hole
which in the newer  image seems to have been filled with a greyer limestone so may be easy to spot on the ground.
There are others in other parts also .

Hmm, sadly i'm less convinced by the vein you can see cutting down by the track, still would be worth returning for a trip to have a look at the terraces, and see about that possible engine shaft.

As A.R. Says we saw a possible climbing shaft which could be a better hope. It's further west along the vein, so closer to the end of the vein.

So i'll be going back for a prod at that at some point.

Big jim has told me loads of times that convenience should be dug more to see where it goes, and i'm inclined to agree with the newt spotting twitcher.

A.R. Certainly knows what he's looking at when he's looking at the faces of the quarry. There is ooodles of water washed rock when you know what you're looking for and most of it is in the south western faces of the quarry near convenience. It's just amazing to see one side of a cave wall that has been uncovered by quarrying.

Shhhhhh!  Adam Newts? have you seen the impact they make in the construction / planning world. (y)

Ric, its only Great Crested Newts that have protected species status.... but they are present at the site, Ive recorded them several times in the over last few years and sent records in to the county recorder. Doubt they impact on us cavers though but at same time a few GCNs wouldn't be enough to prevent, for example, the quarry being re-worked. Unless its a regionally or nationally significant population they never prevent any development but just make life a bit tricky for the developers.

As per the details on the DCA website, sign the log book in the box on the back of the gate then off you go....

ELDON QUARRY BOREHOLE 1 (CLOSE TO ROAD)
JULY 1958

Depth = 605 feet        Width = 6 inches                Drilling Co. = F. Smith & Sons(Grimsby) Ltd
86?  of  6?? x 1/8??x 5/16?? steel tubes (heavy)  to  88? BGL (Brown, Gibbons & Lang) tubes grouted in.
Rest level of water below top = 300?
Pumping Test :-  The first test was carried out when the borehole depth was  402? with a submersible pump fixed at 370?    Duration was  52 hours and flow dropped to 350/400 g.p.h. from a level  of 370?      A considerable amount of waste oil was present in the water.
The second test was at the bore depth of 600?  with suction at 38?0      Yield was 565 g.p.h.  for  18 hours with slight trace of oil in the water.

Also does anyone know at what depth below the quarry floor that water might be encountered?

300' from road level, so probably more than 200' below the quarry floor.

Sorry I don't know if I'm wrong or not .
I used the BGS mapping page and went off the indicated location. The first page of the scan shows an amendment. The location "At" MamTor has "(sic) (Eldon Hill Quarry {+3 chars})" added. The second page has a NGR of SK 1137 8159 that is Eldon Hill between the quarry and the road.
I'm not saying the BGS mapping is correct, there's a bore hole mapped in the middle of Settle that is at the far end of Giggleswick Scar!

Sorry, I wasn't saying you were in the wrong place, I was saying that wasn't the original borehole scan to which I was referring in my earlier post. That one was in the quarry bottom whereas the Mam Tor/Sparrowpit borehole looks like it's above the quarry. In any case both the reports should show the altitude at the surface of the borehole. Bear in mind that the quarry floor is now lower.
