There are two works that are important for this area of Arizona research. The first is Will C. Barnes's Arizona Place Names (Tucson: University of Arizona Press, 1988), which is a reprint of the classic 1935 edition. This work intersperses facts with the state's folklore to help understand place-names in the state. The second resource is Henry P. Walker and Don Bufkin's Historical Atlas of Arizona, 2d ed. (Norman: University of Oklahoma Press, 1989), which provides details on the development of the state.
The United States Geological Survey (USGS) has topographical maps of Arizona for sale, which can be found at www.usgs.gov. The USGS also has a large map library in Flagstaff that is open for research and is located at the USGS Library, 225 N. Gemini Dr., Flagstaff, AZ 86001. USGS state information can be accessed from the main USGS website (see page 5).
