Pima County

Pima County, the second largest of the four original Arizona counties, was created in 1864 and included most of the Southern Arizona land acquired from Mexico by the Gadsden Purchase. Although greatly reduced from its original size, Pima County still covers 9,184 square miles. It ranges in elevation from 1,200 feet to the 9,185-foot peak of Mount Lemmon.

The San Xavier, Pascua Yaqui, and Tohono O'odham Reservations together account for ownership of 42.1% of county land. The State of Arizona owns 14.9% and the U.S. Forest Service and Bureau of Land Management own 12.1%. Other public lands account for 17.1% of the county area, while individual or corporate ownership accounts for 13.8%.
