The Arizona State Archives contains about 32,000 Arizona maps, dating from the 1860s to the present. The Map Collection focuses primarily on Arizona from the territorial period (1864) to the present. It includes commercial and government maps of the territory and state, county and city maps dating from the 1890s, historic topographic maps and Sanborn Fire Insurance maps on microfilm. Other collection strengths include: maps showing irrigation and urban development of the Salt River Valley, U.S. forest maps from 1909 to the present, land grant maps from the 1880s, land ownership maps of Maricopa County (1903 – 1929), railroad right-of-way maps and highway maps. In addition to early territorial maps, the collection includes selected pre-1864 maps of the U.S. Southwest and Mexico, and 17th and 18th century maps of North America.
The Map Collection houses plat maps for Maricopa County (Books 1 – 99) and Pinal County (Books 1 – 21).
Aerial photography for the Phoenix area is available from 1958 to 1997. The collection also houses maps distributed through the Federal Depository Library Program and serves as the Regional Federal map collection for Arizona.
Some of the collection’s maps are online at the Arizona Memory Project.
