The National Atlas provides “reference and outline maps of the United States that you can print or use online. The reference maps display general reference features such as boundaries, cities, capitals, major highways, rivers and lakes, and terrain. Outline maps showing county boundaries, State boundaries, capitals, or other basic features are also available.” The maps are provided in color, as GIFs and PDFs, but will apparently print out nicely in grayscale.
