For a small area, the Missouri River valley west of St. Louis has played an outsized role in the country's history. This 120-page hardcover book, designed for young readers and their families, takes a brief look at each of nine generations that have grown up in nine different river communities since Lewis & Clark plied the river for their epic Voyage of Discovery. Each generation observes changes in the river and environment. Illustrated with original paintings by Bryan Haynes. Introduction by the President of the Missouri History Museum.
