Designed as a companion volume to the newly revised and expanded National Geographic World Atlas for Young Explorers, this United States atlas uses colorful photo essays, double-page physical and political maps, stat boxes, and special "More Abouto?" sections to provide young explorers with in-depth, up-to-date, carefully researched information about each state, region, territory, and the District of Columbia. The state maps include economic symbols for agricultural, industrial, and service industries-a feature unique to National Geographic. Information-packed thematic maps focus on topics such as population, federal lands, territorial growth, endangered U.S. species, and transportation. Throughout, locator maps and color coding make it easy to keep track of where you are and make it simple to flip from region to region or state to state for quick comparisons. Backmatter includes comparison charts, U.S. superlatives, glossary, Web sites, and a comprehensive index. The combination of large, detailed yet easy-to-read maps-both physical and political-stunning, full-color photo essays, and information-packed thematic spreads sets this atlas apart from every other U.S. atlas currently available for ages 8 to 12 and makes it an invaluable resource.
