How does our environment affect us? How do humans affect the environment? The American Memory collections are rich with maps depicting landforms, topography, geology, recreational and wilderness areas. The Conservation and Environment collection maps depict early exploration and subsequent land use in the United States. Studying these maps can help students learn how the American landscape has changed over time.
Featured Map: Using this 1970 National Atlas, let's explore how a map of this type might be used in the classroom. The atlas contains many types of physical maps outlining landforms, geophysical forces, geology, soil, water, climate and marine features. Zoom into this geology map to learn more about the geological history of the United States. What is the U.S.Geological Survey and what does this organization do? What color on the map key represents the oldest geologic period? What regions of the United States have volcanic rock formations? What type of sedimentary rock deposits can be found in your state?
Learning More: Explore the Mapping the National Parks collection for maps and special presentations documenting the growth and development of Acadia, Grand Canyon, Great Smoky Mountains and Yellowstone National Parks. Follow the links on the left for a sampling of other environmental maps. Search for early environmental photos taken in YOUR state. Link to additional Conservation and Cartographic items for even more maps. Students can use the Primary Source Analysis Tool as they analyze these maps.
