Rivers can be many exciting things — giant highways for ships, sources of power, suppliers of water for irrigation, creators of magnificent works of nature such as the Grand Canyon and Niagara Falls, or dreadful instruments of destruction.
This fascinating Book To Begin On introduces young readers to the geology of rivers, as well as explains their numerous uses. As an example, the author traces the course of the mighty Mississippi from its beginning as a tiny stream, to its end, where it meets the sea. He shows how man has learned to make water work for him, as it does in the Hoover Dam and in the Tennessee Valley Authority project; he tells the exciting stories of early explorers — Major John Powell who rode the Colorado River long before it was tamed by the building of dams, and Jacques Cartier, who discovered the St. Lawrence over 400 years before it became one of the great world seaways.
In its colorful blending of geology, geography, and American history, Rivers is a particularly valuable addition to the Books To Begin On series.
