On a map, the Mississippi River cuts America neatly in half coursing from Minnesota to the Gulf of Mexico and separating East from West. But the Mississippi is in fact the "spine of our nation," says Stephen Ambrose. It knits the nation together and connects the heartland to the world. It is our great natural wonder, a priceless treasure bought for a fledgling America by the visionary Thomas Jefferson just 200 years ago. Distinguished historians Stephen Ambrose and Douglas Brinkley, with acclaimed National Geographic photographer Sam Abell, explore the length of the Mississippi-from its mouth at Delacroix Island, Louisiana, to its source at Lake Itasca, Minnesota. The result is this lavish, entertaining, engrossing chronicle of the "father of the waters," which has shaped the history, the culture, and the very landscape of America. Highlighted by Sam Abell's evocative contemporary photographs and wonderful period illustrations, artwork, documents, and maps, this extraordinary panorama of America's heartland offers a lively, informative journey through the history and the landscape carved by the mighty Mississippi.
