I'm also fairly stoked to have discovered that the US Geological Survey allows you to view &/or order historical maps online. I'm currently working out how to use cartography within my project, & how to expand/juxtapose the uses of image & text in my work.
Since the text of a memoir is a map in another (more esoteric) way, I'm curious how I can add physical maps, & physical landscapes to a text largely about the interior landscape. As I mentioned in my blurb, the missoula project is about shaping. Shaping of children into adulthood & shaping of geography by catastrophe. I'm wondering how cartography can play a role in the shaping of the project.
Experiments to follow I'm sure. I've already tried a few things with anatomical drawings... another increased interest of mine is the idea of the physical body as receptacle of language. & really, anatomical drawings are merely maps of another kind.
