Pinal County Information
The county was founded in 1875 from parts of neighboring Maricopa County and Pima County

The county seat is Florence. 

Pinal County contains parts of the Tohono O'odham Nation, the Gila River Indian Community and the San Carlos Apache Indian Reservation, as well as all of the Ak-Chin Indian Community.



In the early 1880s, the small community of Ray grew up around a mine that had tapped into a rich copper deposit.
In those early years, it took awhile to build a proper Courthouse like the one seen here.

Pinal County was formed from portions of Maricopa and Pima counties on Feb. 1, 1875, in response to the petition of residents of the upper Gila River Valley, as Act #1 of the Eighth Territorial Legislature. Florence, established in 1866, was designated and has remained, the county seat.

The county encompasses 5,374 square miles, of which 4.5 are water. In both economy and geography, Pinal County has two distinct regions. The eastern portion is characterized by mountains with elevations to 6,000 feet and copper mining. The western area is primarily low desert valleys and irrigated agriculture.

The communities of Mammoth, Oracle, San Manuel, and Kearny have traditionally been active in copper mining, smelting, milling and refining. Arizona City, Eloy, Maricopa, Picacho, Red Rock and Stanfield have agriculture based-economies. Apache Junction, Arizona City, Coolidge, Soy, and particularly Casa Grande have diversified their economic base to include manufacturing, trade and services. This expansion and diversification has been facilitated by their location in the major growth corridor between Phoenix and Tucson near the junction of 1-10 and I-B, except for Apache Junction, which is to the east of burgeoning Mesa. Most of the southern 3/4 of Pinal County and a small area in Apache Junction are designated as Enterprise Zones.

The state of Arizona is the county's largest landholder with 35 percent, followed by individuals and corporations, 22 percent; Indian reservations, 23 percent; the U.S. Forest Service and Bureau of Land Management, 14 percent, and the remaining 6 percent is other public land.
