This account of the second Powell expedition is a reprint of the 1962 edition and includes all 50 illustrations and a substantial foreword by William H. Geotzmann.

"One of the seminal books on western history . . . The author was only 17 when he began the expedition, and he honestly hero-worshipped Powell all his life. Yet this bright, sharp account is so detailed and truthful that the reader can see through his enthusiasm to discover Powell's mean spirit and sometimes reckless nature. It's also a great river-running book." —Deseret News

"It was decidedly worth writing, this detailed record: a more absorbing, and at times stirring, story of adventure has not seen the light in a long time, and the author's unadorned, yet vivid, style enables the reader to share all the emotions of the explorers:" —The Nation

"In these later years (1909) when amateur travel in the west is frequent, a detailed record of this kind will be of value to seekers after adventure." —Science

"A document of primary importance in the literature of the exploration of the West . . . While its primary appeal will no doubt be to river runners and river historians, it ought not to be neglected by anyone interested in outdoor living and exploration. Dellenbaugh was equalled, perhaps, only by Major Powell himself in the ability to convey drama and a sense of movement through an almost indescribably spectacular and challenging country, and few readers indeed will be able to leave the book alone until Dellenbaugh has taken them around that last bend in the canyon." —Utah Historical Quarterly
