About Pima County
Pima County covers 9,186 square miles of southern Arizona along the Mexican border. The Sonoran Desert covers the county, typified by creosote bushes, and scatterings of saguaro cactus, teddy bear cholla, prickly pear cactus. Numerous small ranges of barren, rocky mountains divide the terrain into wide valleys, which slope gently towards the mountains. Saguaro National Park, in mountains next to Tucson, and Organ Pipe Cactus National Monument on the Mexican border preserve significant tracts of the Sonoran Desert.
The Tucson metropolitan area occupies the northeast part of the county and aside from this area, towns are small and widely separated. Much of the county is part of the Tohono O'odham Indian Reservation and much of the remainder is covered by federal lands, including the National Parks, wildlife refuges and military reservations.
With the 2000 census, Pima County's population stood at 843,746, most of whom live in the Tucson area. Interstate 10 crosses the northeast corner of the county, passing through Tuscon, and Interstate 19 connects from Tucson to the Mexican border at Nogales. State Highway 86 crosses the county from east to west, passing through the Tohono O'odham Indian Reservation. State Highway 85 traverses the western end of the county from north to south, and is the main access to Organ Pipe Cactus National Monument.
