Tucson: El Presidio

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.

Arizona is renowned in the United States for the Grand Canyon, carved by the Colorado River in the state’s north. Its terrain extends from the Sonoran Desert, where saguaro cacti define the south, to ponderosa pine forests and the high plateaus of the Colorado Plateau. The red-rock country around Sedona and the sandstone buttes of Monument Valley are enduring symbols of the American Southwest. Indigenous heritage remains central: Arizona is home to 22 federally recognized tribes, including the Navajo Nation and Hopi Tribe. Historic Route 66 also passes through northern communities such as Flagstaff and Kingman. Discover other points of interest through webcams located across Arizona.

The Atlantic, Pacific and Gulf coasts define much of the United States — their ports, fisheries and trade routes have long tied the country’s economy to the wider world. Between them, the Rocky Mountains, Great Plains and Mississippi River basin form sharply different regions, from high western ranges to broad agricultural heartlands. Cities carry much of the national story: New York’s Statue of Liberty, a gift from France dedicated in 1886, remains an enduring symbol, while Washington, DC concentrates major federal institutions. Indigenous nations have shaped these lands for millennia, and their living cultures remain essential to the country’s identity.
