[10.] See Major C. E. Dutton's map of the plateau country in 6th Ann. Rept. U.S. Geol. Survey, pl. xi. His report on "Mount Taylor and the Zuñi plateau," of which this map is a part, presents a vivid picture of the plateau country, and his descriptions are so clear and expressive that any attempt to better them must result in failure. The statement of the geologic and topographic features which is incorporated herein is derived directly from Major Dutton's description, much of it being taken bodily.
