Newbery and Caldecott Medal winner James Daugherty has applied his literary and artistic skill to the remarkable expedition of Meriwether Lewis and William Clark on their 3555-mile trek from St. Louis to the Pacific Ocean. Taken largely from original accounts of the expedition, Daugherty has written in his simple, forceful, and lyrical way to evoke the drama and pathos of what was one of American’s most daring journeys of discovery.
