----------------------------Original message---------------------------- Hello all, A colleague and I need your assistance. We have a graduate student working on her Ph.D. in Land Architecture and her topic, in a nutshell, is how the United States was settled using maps to show the progression. She is investigating how explorers used trails to travel, where traders and armed forces located posts and forts, and which posts and forts become towns, etc. She will then show how Iowa was settled using similar ideas. Her first question to us is that she needs information about the Jefferson Grid. When asking for more information we learned that the phase Jefferson Gris is not used very often. However, she indicated that the National Land Survey is its base. Can any of you help us to locate information about the grid. Her second request concerns maps showing the progression of human settlement across the country, before and after, the National Land Survey. Specifically she wants maps showing old trails, Indian settlements, trading posts, forts and early communities. Any ideas of maps, textual information and other stuff to help her? Can any of you help? Any and all would be greatly appreciated. Thank you in advance. --- Kathy A.
