The team assembled to carry out this geological survey of the Grand Canyon included some outstanding talents: C.E.Dutton, the scientist; Jack Hilliers, the photographer and of course Holmes and Moran as artist-topographers. The intention of the survey was strictly scientific, but as Dutton writes in his preface, "I have in many places departed from the severe ascetic style which has become conventional in scientific monographs." This is also true of Moran and Holmes: both were clearly inspired by their subjects. The overall result is of a quality that would not be possible today. As Wallace Stegner wrote in his introduction to the 1977 reprint: "Later specialization has eliminated from scientific publications most of the elements that make The Tertiary History so charming. No report written as this one is written would now be published by any government bureau. No illustrators like Moran and Holmes would be permitted to illustrate it... A great book... The Tertiary History has kept its value precisely because it does not specialize."
