Early history

The early history of Arivaca is obscure. It was probably a Pima or Tohono O'odham village, abandoned after the Pima Indian Revolt of 1751. Spanish settlers developed small mines.

In 1833 a Mexican land grant of 8,677 acres (35.11 km2) was approved, which became La Aribac ranch, a Pima word for "small springs". Charles Poston bought the ranch in 1856, and the reduction works for the Heintzelman Mine, at Cerro Colorado, were then erected at Arivaca. The Court of Private Land Claims eventually disallowed the Arivaca Land Grant. The US Post Office was established April 10, 1878, with Noah W. Bernard as the first Postmaster; still in operation at ZIP code 85601. Freighter and rancher Pedro Aguirre established a stage stop in Arivaca and the Buenos Aires Ranch. In 1879 he built the historic Arivaca Schoolhouse, which was listed on the National Register of Historic Places in 2012, as the oldest standing school building in Arizona.

Arivaca was a camp for at least three United States Cavalry units during the 1910-20 Mexican Revolution: Troop B of the Connecticut National Guard/The First Company Governor's Horse Guards (1916), the Utah Cavalry (1917) and the 10th Cavalry (1917–20).

Arivaca mining district

The historic Arivaca mining district consists of over 100 old mines in the Las Guijas Mountains northwest, the San Luis Mountains to the southwest and Cobre Ridge to the southeast of the town. Gold, silver, lead, copper and tungsten production has been recorded starting in Spanish colonial times and continuing intermittently through the 1950s.

Recent history

Arivaca had a small population until the Trico Electric Cooperative power lines arrived in the valley in 1956. In 1972 the Arivaca Ranch sold 11,000 acres to a land developer who subdivided the property into 40-acre parcels. Four years later, the dirt Arivaca Road was paved.

In the 1980s and 1990s many new residents moved into the area, and a medical clinic, fire department, arts council, human resource office, community center and branch of Pima County Public Library were opened.

In 2012 the Arivaca Schoolhouse, the oldest standing schoolhouse in the state, was added to the National Register of Historic Places. A former nursing home was turned into the Arivaca Action Center with a focus on education, the arts, wellness, hospitality and sustainability. The AAC offers space for meetings, overnight guests, gardening, and physical therapy.


According to the Köppen Climate Classification system, Arivaca has a semi-arid climate, abbreviated "BSk" on climate maps.

In 2011 community members created Arivaca Alive, with a mission to develop programs and activities to increase the number of visitors to the community to support local businesses. Exposing visitors to the residents as part of a larger rebranding effort was an equally important goal. The group initiated First Saturdays in Arivaca with themed monthly events. In 2013 the group began a campaign branding Arivaca as a weekend destination built around the eco tourism attractions in the area including: birding, hiking, boating, gardening, and ghost town hunting. The organization sought to expand its reach to publicize other activities in the community throughout the year including: Dia de los Muertos, Arivaca Memories & Music Festival, Arivaca Film Festival, Chili Cookoff, Cinco de Mayo and Fourth of July Parade.

Local businesses in Arivaca include: Arivaca Mercantile, Arivaca Artists' Coop, La Gitana Cantina, Gadsden Coffee, Arivaca Soul Food and Universal Ranch RV Village, La Siesta Campground, Virginia's Rancherita Food Truck, and The Arivaca Boys Ranch.

U.S. Decennial Census

Arivaca first appeared as "Aravica Mines" on the 1860 U.S. Census when it was in the short-lived Arizona County in New Mexico Territory. Of the 61 residents, 52 were White and nine were Black. The nine Black residents accounted for the largest community of Blacks in what was to be Arizona (Tucson then had eight). It would not report again until 1890 as the unincorporated village of Arivaca. It did not appear on the 1900 census. It next appeared as the "Arivaca Precinct" in 1910 through 1930, though this included the general area surrounding the village. It reported a majority of "other" (likely Hispanic/Spanish) when the racial demographics were reported for the precinct in 1930. With the combination of all county precincts into three districts in 1940, it did not formally appear again until 2010, when it was made a census-designated place (CDP).


The settlement is served by Sopori Elementary School, Sahuarita Middle School, and Sahuarita High School, all part of the Sahuarita Unified School District.


Arivaca Road connects with I-19 at Amado, approximately 23 miles (37 km) to the northeast and with Arizona State Route 286 some 12 miles (19 km) to the west in Altar Valley.
