*high-fives* What happened to me was ineptshieldmaid egged me on. And then I tried to look for a base map and realised that all the available maps of Narnia are kind of shite and either make no sense according to the books, make no sense according to LOGIC (Walden Media's map, unless I am very much mistaken, is going to need the Great River to flow uphill at one point) or have no scale and no landmarks on them.

... so I sort of speedread all the books and made my own ... and the geological map is the next in the series.

I want to see your geological map of Middle Earth! Please tell me you have a copy?
