"The purpose of this guide is to point out the more important relations of the rocks and to outline their history and the conditions under which the canyon was developed. Care has been taken to avoid technical terms as far as possible so that most persons should have no difficulty in understanding every part. The maps, cross sections and lettered views will aid greatly in connecting the descriptions with the objects themselves." - from the Introduction.
"A convenient summary widely used in its day and still useful." Farquhar 76. Grand Canyon Bibliography: 21.736.
