Dinorwic has not been my study! It's unfortunate that there was no large scale OS mapping published of Dinorwic between the 3rd edition of the 25in. in 1912-14 and the National Grid post 1970! Just the period of maximum change. I did start to try to label the 1912-14 version once but it's very easy to get confused. I think this shows Juliet and Harriet below the steam mills - anyone else want a go ?

It continues uphill:

As for the power station, there's a ventilation chimney up from the main caverns - see this diagram, but I think that comes out much higher up!

The map is the territory - especially in chain scale.
