<DIV>In this book Wallace Stegner recounts the sucesses and frustrations of John Wesley Powell, the distinguished ethnologist and geologist who explored the Colorado River, the Grand Canyon, and the homeland of Indian tribes of the American Southwest. A prophet without honor who had a profound understanding of the American West, Powell warned long ago of the dangers economic exploitation would pose to the West and spent a good deal of his life overcoming Washington politics in getting his message across. Only now, we may recognize just how accurate a prophet he was. <p> "This book goes far beyond biography, into the nature and soul of the American West. It is Stegner at his best, assaying an entire era of our history, packing his pages with insights as shrewd as his prose." ?Ivan Doig</DIV>
