By now every literate American knows who Stephen E. Ambrose is. The author of the best-selling Undaunted Courage, about the Lewis and Clark expedition, he was also Ken Burns's primary source for the TV documentary. Now Ambrose returns with Lewis and Clark: Voyage of Discovery. More than a rerun of the author's favorite topic, this beautiful new book combines Ambrose's personal account of his family's retracing of the journey, along with historical background and excerpts from Lewis and Clark's journals. As always with Geographic publications, all the illustrations and layout are wonderful, with paintings, drawings, maps, and dozens of stunning photographs by National Geographic veteran Sam Abell. The result is as much a photographic journey as it is a historical one. The Corps of Discovery, as Jefferson designated them, performed one of the great explorations, and created an enduring American myth. No one describes it better than Stephen Ambrose.
