Tubac Presidio State Historic Park, located in Tubac, Arizona, US, preserves the ruins of the Presidio San Ignacio de Tubac and various other buildings, thereby presenting a timeline of European settlement in this Southern Arizona town. The park contains a museum, a number of historic sites, an underground archeology exhibit displaying the excavated foundations of the Tubac Presidio, and a picnic area. Various cultural events are held on-site throughout the year, including Anza Days (October), Los Tubaqueños living history presentations (Sundays from October through March), archeological tours, and nature walks. Until recently, the park was administered by Arizona State Parks but is the first park in the Arizona state park system. As a result of budget cutbacks, the Tubac Presidio was scheduled to be closed in 2010, but was rescued by local residents and the Tubac Historical Society. It is now operated by The Friends of the Presidio and staffed with dedicated volunteers.

The Presidio of San Ignacio de Túbac or Fort Tubac was a Spanish built fortress. The fortification was established by the Spanish Army in 1752 at the site of present-day Tubac, Arizona. Its ruins are preserved in the Tubac Presidio State Historic Park.

Mission San José de Tumacácori (O'odham: Cemagĭ Gakolig) is a historic Spanish mission near Nogales, Arizona, preserved in its present form by Franciscans in 1828.

Tumacácori National Historical Park is located in the upper Santa Cruz River Valley in Santa Cruz County, southern Arizona. The park consists of 360 acres (1.5 km2) in three separate units. The park protects the ruins of three Spanish mission communities, two of which are National Historic Landmark sites. It also contains the landmark 1937 Tumacácori Museum building, also a National Historic Landmark.

Tumacacori (; O'odham: Cemagĭ Gakolig) is an unincorporated community in Santa Cruz County, Arizona, United States, which abuts the community of Carmen. Together, the communities constitute the Tumacacori-Carmen census-designated place (CDP). The population of the CDP was 393 at the 2010 census.

VERITAS (Very Energetic Radiation Imaging Telescope Array System) is a major ground-based gamma-ray observatory with an array of four 12 meter optical reflectors for gamma-ray astronomy in the GeV – TeV photon energy range. VERITAS uses the Imaging Atmospheric Cherenkov Telescope technique to observe gamma rays that cause particle showers in Earth's atmosphere that are known as extensive air showers. The VERITAS array is located at the Fred Lawrence Whipple Observatory, in southern Arizona, United States. The VERITAS reflector design is similar to the earlier Whipple 10-meter gamma-ray telescope, located at the same site, but is larger in size and has a longer focal length for better control of optical aberrations. VERITAS consists of an array of imaging telescopes deployed to view atmospheric Cherenkov showers from multiple locations to give the highest sensitivity in the 100 GeV – 10 TeV band (with sensitivity from 50 GeV to up to 50 TeV). This very high energy observatory, completed in 2007, effectively complements the Large Area Telescope (LAT) of the Fermi Gamma-ray Space Telescope due to its larger collection area as well as coverage in a higher energy band.
