Book excerpt: By examining the life and career of William Clark, this book explores how the North American West entered the American imagination. Clark was among the most important western officials of his generation, and he worked to represent the West during a period of tremendous uncertainty and change. Without ever calling himself a writer or an artist, Clark nonetheless drew maps, helped to produce books, drafted lengthy reports, surveyed the landscape, and wrote numerous journals that made sense of the West and its future for Americans who were fascinated by the region's potential but also fearful of its dangers. William Clark's World situates the descriptive words and pictures created by Clark and his contemporaries at the center of a discussion of western history and cultural development. The book casts new light on the familiar narrative of manifest destiny and on the nation's view of the West in the early nineteenth century. --Book Jacket.
