Mountains North of Flagstaff, Arizona
Detailed view of the San Francisco Peaks, Mountains, prepared as part of the United States survey for the most practicable route for a railroad line to the West Coast of America, conducted just prior to the Civil War.
The San Francisco Peaks range, also called San Francisco Mountain, consists of 6 peaks, Humphries Peak, Agassiz Peak, Fremont Peak, Aubineau Peak, Rees Peak, and Doyle Peak.
Humphreys Peak was named about 1870 for Brigadier General Andrew Atkinson Humphreys, a Civil War hero and U.S. Chief of Engineers. Humphreys' link to Arizona was that he directed the famous Wheeler Surveys, the United States Geographical Survey that explored the region west of the 100th Meridian, mostly in the southwestern United States. The surveys, done in the 1870s, were lead by Captain George Wheeler.
Humphreys was a Civil War General, who led Union troops at Gettysburg, Fredericksburg, Chancellorsville, and others. His troops called him "Old Google Eyes" for his reading glasses, but he was a profane and no-nonsense soldier. Charles Dana, Assistant Secretary of War, called him "one of the loudest swearers" he ever heard and a man of "distinguished and brilliant profanity."
