From the Introduction- "Geologically, the significance of the Canyon has been realized since the courageous journeys of Powell a century ago. Nowhere is there exposed a better view of the earth's crust through the sedimentary veneer into the underlying metamorphic basement complex. Although the grandeur of the geology in the National Park is world famous, the region of the Canyon to the west displays a late Cenozoic history of volcanism and tectonism not widely appreciated. It is the purpose of this guidebook to summarize what is currently known of the western Grand Canyon region."
