Forget this, was going to say something stupid. 😞

I got confused because there appears to be two Graig Ddu's. Another at SH618574. Rockclimbing.

---

There are quite a few "Graig Ddu"s about (also spelt Craig Ddu) it means Black Rock. It is finding another one with a stone quarry that is the tricky bit! 😉

I supppose one could always ask the Royal Commission on the Ancient and Historical Monuments of Wales who hold the original. I mean they should know where it is. :angel:

The supposedly aerial photo of Graig Ddu I would imagine could be a quarry somewhere in the USA or otherwise. Diphwys does not resemble anywhere in Ffestiniog.
Which reminded me that this is the websit that made me realise that the slate museum at Llanberis had forgotten where the Smith excavator had come from.
I typed in Smith Rodley into the aol search and up came Jewels website with an absolutely obsurd description of it. Even stating that it worked at Gloddfa ganol.
Well I contacted them and told them that the information on their site was incorrect. They then ammended the information. It is not 100% but not far off. I was informed that they were given the information by Llanberis.
I then got in touch with the slate museum at llanberis and eventualy things worked out ok. We started the machine last week and had a bit of a playabout with it.
I sugest Johncaernarfon inform the website of the mistakes as he has the better grammer and has the knowlage. What do you think?

On the google earth type in sh7145 and it will bring you above Manod lake. Graig Ddu is forward and covers an area from the bottom of the incline to about half of what is now known as Cwt Y Bugail quarry. 😉

I doubt anywhere other than Wales because those photos are part of the Historic & ancient monuments collection of Wales. Unless they had a bad pilot! :lol:

The GE of Graig Ddu.

The photo of Graig Ddu, is in fact the limestone (carboniferous) quarry below Gilwern Hill at Clydach. (SO233128). It's quite visible off the "Heads of the Vally" road, which I travel occasionally. The viaduct carried a rail link, the area is fascinating for the amount of industrial archaeology visible.

Ah yes! So it is! I have just looked at it on Google Earth (sorry I don't know how to do link of GE onto here).

It would seem from the GE image that the large mine building behind the viaduct has now been demolished.

I agree, just been looking at a close up of GE. I've been trying to upload the HD image but the gremlins have arrived. Will post when sorted.

Gremlins gone hopefully.

The cords are 51 48 32.75n 3 06 42.95w
SO 234129 ( not disagreeing with Wyn, just depends on the point you take)

I agree with earlier posts that they should be informed of these errors.

---

Culturenet/National Library of Wales seem incommunicado by email, the service being temporarily suspended. I take it that others have discovered this.
Looks like a telephone job!

Off you go then. 🙂

---

It would seem the error (at least as far as Diphwys is concerned, haven't checked Graig Ddu yet) has been made by Royal Commission on Ancient & Historical Monuments of Wales as they are the source. The "Oakeley" photo is listed as being "Diphwys on their website too.

Just checked Graig Ddu, yes, error is there.

Just sent an email off to Royal Commission on Ancient & Historical Monuments of Wales with details of the two errors plus a link to this forum.

Thank you, JnC.
I hope they pay attention!
I wouldn't expect there to be anybody to answer the 'phone at the weekend!

Good on you John. Strange that there are so many mistakes on this website. I wonder how many other mistakes there are on other subjects.

---

Yes, does make you wonder. Maybe I can understand getting different slate quarries in same town getting mixed up. How on earth they mixed up a stone quarry in South East Wales with a slate quarry in North West Wales I can't imagine! :oops:

Sorry to have appeared to have dropped out, computer problems!
In order to make this blindingly clear for any visitors that JnC's email and link might bring:-
Image GTJ 28667 is not Graig Ddu, Ffestiniog (NGR SH725455) but Gilwern Hill, Clydach. NGR SO233120.
An easy mistake to make...but.. we know how these mistakes come about and the systems that are normally put in place to prevent them. Who was asleep? Are they still asleep?
Talking of which..Slate Quarrying in Wales. Richards.2006. Gwasg Carreg Gwalch. The biggest mess of syntactical and typographical errors I've seen in years.
