Hello all, I know I don't post here, wel lat all really, but could really use your input on correlating all the evidence at Dinorwic.

Based on hours of studying maps, plans, old photos, new photos, wandering around the place, I've drawn up [url="http://www.quarryscapes.co.uk/dinplan.jpg"]this schematic.[/url]

Trouble is there is a hell of a lot of inconsistencies between sources. The department names I have derived from the 1830s Ellis map (Delving in Dinorwig), the level names have been painstakingly associated to levels from the sketch map in Delving in Dinorwig and also Slates to Velinehli but they don't always agree. The big spanner in the works is the 1989 OS map - which smatters names from the sketch map all over the shop completely at a variance to where I've logically worked them out to be!

So who is right? - and if anyone can help make sense of the lower levels, I would be really grateful! Unfortuantly I wasn't around in the 70s, so have absolutely no idea of what the lower end used to look like, and how departments were connected!

I'm also aware of the sxistence of a few tunnels that don't seem to be marked on maps, and as I have not actually found them myself am not sure where they are! (The ones climbers play in - particularly the Snakes and Ladders (and Tunnels) route.

Would very much love to hear your input guys and gals!

Hi Alan,

A very interesting project.

First of all a couple of questions. What do the blue (lower case) letters mean? I assume the black squares/rectangles filled in grey refer to pits? What are the grey diagonal lines?

Might it be helpful to include the level references as well as the names? For instance C5A, C5B, C5T etc?

I will add points here as I come across them.

Firstly, the "new" C2 incline was four track at the bottom but only two at the top. There was a second drumhouse half way up the incline to operate this. I do not know if the "old" C2 incline was the same.

Would it be possible to make a "medium sized" version of this available online too please? As it first appears (fitted to screen) it is minute and writing impossible to read. When you click on the "view full size" icon you can only see a very small area of the diagram at a time.

Ctrl+ and Ctrl- works for me (zooms in and out in Firefox).

That does look like a great project!

Hi John, the little letters refer to notes that are on a naccompanying page in the PDF version, I should have linked to that really as it has the key to the diagram in it, but I had planned on just embedding the image. If you change the extension to .pdf you'll get the accompanying notes too but I need to rewrite a few of them - one of which concerns the C2 incline as mentioned. (I should stop being lazy and redraw the incline really!)

Areas delineated in light grey are the quarry pits, oblongs with grey fill are tunnels.
