When Frederick Dellaenbaugh was young, he traveled with John Wesley Powell to the Colorado River with the aim of exploration and research. The crew sailed down the Colorado River to the Great canyon. The spirit of adventures seized the young man and he got carried away. And he decided to share his impressions with other people using his sense of humor in depiction of his adventures. At the same time there is a sense of sadness in the book every time we meet American Indians who had to move from their native territories further and further. The author says himself that when he looked into their sad eyes he understood their pain. It was not easy for those American Indians who decided to stay where they lived before to accommodate to the life with the white colonizers. Dellenbaugh managed to include so many aspects of humans' life and nature description in his book so that it is definitely worth reading.
