The Atlas of the Historical Geography of the United States offers map after map after map, some of historical interest, others with relevance today:
- Cultivated crops.
- Soil regions.
- Drought frequency.
- Oil and gas fields.
- Indian tribes.
- Spanish, French, and American explorations.
- States, territories, and cities.
- Colleges and universities.
- Political boundaries.
- Political parties.
- Overland mail routes.
- Distribution of wealth.
And that is just the beginning.
Whatever your interest is, you are bound to find this atlas a fascinating place to start your research. Makes a good companion to Peopling the Plains by James Shortridge. Also a good visual for the children. Highly recommended.
