This beautiful 17" x 37" map was made by the United States Office of Explorations and Surveys. It shows relief by shading and hachures (short parallel lines used in hill-shading on maps, their closeness indicating steepness of gradient), and tracks the routes of exploration. If you look closely (right click the image), you can see a small pueblo village and "Fort Defiance". We found it in the archive of the Library of Congress.
If you would like to buy a copy in silk or paper, we have them here.
