Maps show magnetic intensities (horizontal and vertical), political boundaries, bodies of water, coastlines and islands. Maps include legends, latitudinal and longitudinal lines, as well as bar scales and scale statements. Presented with Albers Equal Area Projection. With two inset maps within each map: [Principal islands of Hawaii] -- [Alaska]. Colored lithograph. Map is 42 x 31 cm, on sheet 49 x 35 cm. Accompanying descriptive text on page 55. Maps appear in Special subject maps section, subsection Physical : Geophysical forces.

Topic covered: physical geography, history, economics, culture, administrative boundaries and cartography. In addition, atlas also provides maps of the world, as related to the United States. Maps show political boundaries, cities, railways, roads, topography, bodies of water, glaciers, drainage, coastlines, islands, water depths and time zones. Topical maps feature other details, such as history, geology, climate, agriculture, population, racial demographics (including indigenous peoples), religion, language and transportation. Some maps use data visualization to further illustrate geographical information, with charts overlaid upon the landscape.
