Topographic maps show the shape and elevation of the terrain using contour lines and name prominent natural and cultural features. Topographic maps for the U.S. are produced by the U.S. Geological Survey (USGS), with the 7.5 Minute series offering the greatest detail and complete coverage for the country. These are the most commonly used maps and, at a scale of 1:24,000 (1 inch = 2,000 feet), they have the greatest level of detail.

The library has several additional USGS topographic map series in print.

You can find more information about topographic maps at these sites.
