Pulitzer Prize winner Wallace Stegner recounts the remarkable career of Major John Wesley Powell, the distinguished ethnologist and geologist who explored the Colorado River, the Grand Canyon, and the homeland of the Southwest Indian tribes. This classic work is a penetrating and insightful study of the Powell's career, from the beginning of the Powell Survey, in which Powell and his men famously became the first to descend the Colorado River, to his eventual expulsion from the Geological Survey. In masterful prose, Stegner details the expedition, as well as the philosophies and ideas that drove Powell.
