Tucson

Few cities in Arizona have a history as closely tied to the Santa Cruz River valley as Tucson. The city sits in the Sonoran Desert, with the Santa Catalina Mountains rising to the north and other ranges defining the basin around it. Long before the modern city, the valley was home to Hohokam communities; Spanish settlers later established the Presidio San Agustín del Tucson in 1775. Today, the University of Arizona gives central Tucson an academic presence, while the historic Fourth Avenue district and downtown reflect its layered borderlands identity. South of the city, Mission San Xavier del Bac is a major landmark of Spanish colonial Arizona.
