"As graphic and as interesting as a novel.... Of especial value to the average reader is the multiplicity of pictures. They occur on almost every page, and while the text is always clear, these pictures give, from a single glance, an idea of the vastness of the canyons and their remarkable formation, which it would be beyond the power of pen to describe. And the color reproduction of the water-color drawing that Thomas Moran made of the entrance to Bright Angel Trail gives some faint idea of the glories of color which have made the Grand Canyon the wonder and the admiration of the world."—The Cleveland Leader.

"His scientific training, his long experience in this region, and his eye for natural scenery enable him to make this account of the Colorado River most graphic and interesting. No other book equally good can be written for many years to come—not until our knowledge of the river is greatly enlarged."—The Boston Herald.
