Hehe, sorry
What do you want to know?
There's not very much to it really, they're just textures screen captured from Google Earth (so sue me!) and stitched together to make something high resolution.
I take each image and set it to tile in x and y and plug it into the child input of a surface layer and then break them up with a power fractal. Set the PF (breakup shader) scale to something reasonably big so you have a black and white mask with large enough areas of black and white so it hides the repeat pattern of the tile.
That really is pretty much it. The more layers you add in the more detailed it gets. You can also use the images to break up PF textures and of course visa versa.
The rock face texture is from CGTextures and is mapped to lateral projection.
Hope this points you in the right direction.
