This book is a firsthand account of the first U.S. government-sponsored passage through the Grand Canyon. The author, a one-armed Civil War veteran, and his team of nine men risked their lives to accomplish this feat in 1869. They faced dangerous rapids, food shortages, and potential attacks from Native American tribes. The narrative provides detailed descriptions of the geography, geology, and Native American inhabitants of the region, offering invaluable insights into the uncharted territory of the American West.
