For over a thousand years, prehistoric farmers inhabited much of the present-day state of Arizona. When the first Europeans arrived, all that remained of this ancient culture were the ruins of villages, irrigation canals and various artifacts. Among these ruins is the Casa Grande, or "Big House," one of the largest and most mysterious prehistoric structures ever built in North America. Casa Grande Ruins, the nation's first archeological preserve, protects the Casa Grande and other archeological sites within its boundaries. You are invited to see the Casa Grande and to hear the story of the ancient ones the Akimel O'otham call the Hohokam, "those who are gone." Located near Coolidge.

Hike down into Walnut Canyon and walk in the footsteps of the people that lived here over 900 years ago. Under limestone overhangs, the Sinagua built their homes. These single story structures, cliff dwellings, were occupied from about 1100 to 1250. Come out and see millions of years of history unraveled in the geology of the rocks. Listen to the canyon wren and enjoy the turkey vultures soaring above. And if you look closely, you may even see an elk or a javelina. Different lifezones overlap here, mixing species that usually live far apart. In this canyon, desert cacti grow alongside mountain firs. The people that lived here moved on to become the modern pueblo people of today. Walnut Canyon is one of their ancestral homes. Located outside of Flagstaff.

John Lorenzo Hubbell purchased the trading post in 1878, ten years after Navajos were allowed to return to their homeland from their terrible exile at Bosque Redondo, Ft. Sumner, NM. During the four years spent at Bosque Redondo, Navajos were introduced to many new items. Traders like Hubbell supplied those items once they returned home. Hubbell family members operated this trading post until it was sold to the National Park Service in 1967. The trading post is still active, and operated by the non-profit organization, Western National Parks Association, that maintains the trading traditions the Hubbell family established. Step back in time and experience this original 160 acre homestead, including the trading post, family home and visitor center with weaving demonstrations.

The national trail commemorates the route followed by a Spanish commander, Juan Bautista de Anza, in 1775-76 when he led a contingent of 30 soldiers and their families to found a presidio and mission near the San Francisco Bay. Along the trail route, the visitor can experience the varied landscapes similar to those the expedition saw; learn the stories of the expedition, its members, and descendants; better understand the American Indian role in the expedition and the diversity of their cultures; and appreciate the extent of the effects of Spanish colonial settlement of Arizona and California.

Preserved here are the archeological remains of the Hohokam culture. Hohokam is a Pima Indian word meaning "those who have gone."

Pipe Spring National Monument, a little known gem of the National Park System, is rich with American Indian, early explorer and Mormon pioneer history. The water of Pipe Spring has made it possible for plants, animals, and people to live in this dry, desert region. Ancestral Puebloans and Kaibab Paiute Indians gathered grass seeds, hunted animals, and raised crops near the springs for at least 1,000 years. In the 1860s Mormon pioneers brought cattle to the area and by 1872 a fort (Winsor Castle) was built over the main spring and a large cattle ranching operation was established. This isolated outpost served as a way station for people traveling across the Arizona Strip, that part of Arizona separated from the rest of the state by the Grand Canyon. It also served as a refuge for polygamist wives during the 1880s and 1890s. Although their way of life was greatly impacted, the Paiute Indians continued to live in the area and by 1907 the Kaibab Paiute Indian Reservation was established, surrounding the privately owned Pipe Spring ranch. In 1923 the Pipe Spring ranch was purchased and set aside as a national monument. Today the Pipe Spring National Monument - Kaibab Band of Paiute Indians Visitor Center and Museum explains the human history of the area over time. Daily tours of Winsor Castle, summer "living history" demonstrations, an orchard and garden, and a half-mile trail offer a glimpse of American Indian and pioneer life in the Old West.

Navajo National Monument preserves three of the most-intact cliff dwellings of the ancestral Puebloan people (Hisatsinom). The Navajo people who live here today call these ancient ones "Anasazi." The monument is high on the Shonto Plateau, overlooking the Tsegi Canyon system in the Navajo Nation in Northern Arizona. The monument features a visitor center, two short self-guided mesa top trails, two small campgrounds, and picnic area. In the summer, rangers guide visitors on tours of the Keet Seel and Betatakin cliff dwellings. Tours are usually available during the spring and fall months as well.

Fort Bowie commemorates in its 1000 acres, the story of the bitter conflict between the Chiricahua Apaches and the United States military. For more than 30 years Fort Bowie and Apache Pass were the focal point of military operations eventually culminating in the surrender of Geronimo in 1886 and the banishment of the Chiricahuas to Florida and Alabama. It was the site of the Bascom Affair, a wagon train massacre, and the battle of Apache Pass, where a large force of Chiricahua Apaches under Mangus Colorados and Cochise fought the California Volunteers. The remains of Fort Bowie today are carefully preserved, the adobe walls of various post buildings and the ruins of a Butterfield Stage Station. It stands as a lasting monument to the bravery and endurance of U.S. soldiers in paving the way for westward settlement and the taming of the western frontier.

Well-preserved cliff dwellings were occupied by the Salado culture during the 13th, 14th, and early 15th centuries. The people farmed in the Salt River Valley and supplemented their diet by hunting and gathering native wildlife and plants. The Salado were fine craftsmen, producing some of the most exquisite polychrome pottery and intricately woven textiles to be found in the Southwest. Many of these objects are on display in the Visitor Center museum. The monument is located in the Upper Sonoran ecosystem, known primarily for its characteristic saguaro cactus. Other common plants include: cholla, prickly pear, hedgehog, and barrel cactus (blooming April through June); yucca, sotol, and agave; creosote bush and ocotillo; palo verde and mesquite trees; an amazing variety of colorful wild flowers (February through March); and a lush riparian area which supports large Arizona black walnut, sycamore, and hackberry trees.

For its time and place, there was no other pueblo like Wupatki. Less than 800 years ago, it was the tallest, largest, and perhaps the richest and most influential pueblo around. It was home to 85-100 people, and several thousand more lived within a day’s walk. And it was built in one of the lowest, warmest, and driest places on the Colorado Plateau. Human history here spans at least 10,000 years. But only for a time, in the 1100s, was the landscape this densely populated. The eruption of nearby Sunset Crater Volcano a century earlier probably played a part. Families that lost their homes to ash and lava had to move. They discovered that the cinders blanketing lands to the north could hold moisture needed for crops. As the new agricultural community spread, small scattered homes were replaced by a few large pueblos, each surrounded by many smaller pueblos and pithouses. Wupatki, Wukoki, Lomaki, and other masonry pueblos emerged from bedrock. Trade networks expanded, bringing exotic items like turquoise, shell jewelry, copper bells, and parrots. Wupatki flourished as a meeting place of different cultures. Then, by about 1250, the people moved on.

Crowning a desert hilltop is an ancient pueblo. From a roof top a child scans the desert landscape for the arrival of traders, who are due any day now. What riches will they bring? What stories will they tell? Will all of them return? From the top of the Tuzigoot Pueblo it is easy to imagine such an important moment. Tuzigoot is an ancient village or pueblo built by a culture known as the Sinagua. The pueblo consisted of 110 rooms including second and third story structures. The first buildings were built around A.D. 1000. The Sinagua were agriculturalists with trade connections that spanned hundreds of miles. The people left the area around 1400. The site is currently comprised of 42 acres.

At the base of sheer red cliffs and in canyon wall caves are ruins of Indian villages built between AD 350 and 1300. Canyon de Chelly National Monument offers visitors the chance to learn about Southwestern Indian history from the earliest basketmakers to the Navajo Indians who live and farm here. Located near Chinle.

Nestled into a limestone recess high above the flood plain of Beaver Creek in the Verde Valley stands one of the best preserved cliff dwellings in North America. The five-story, 20-room cliff dwelling served as a "high-rise apartment building" for prehistoric Sinagua Indians over 600 years ago. Early settlers to the area assumed that the imposing structure was associated with the Aztec emperor Montezuma, but the castle was abandoned almost a century before Montezuma was born. With heightened concern over vandalism of fragile southwestern prehistoric sites, Montezuma Castle became a major factor in the nation's historic preservation movement with its proclamation as a national monument. The Castle was described in the December 1906 establishment proclamation as "of the greatest ethnological and scientific interest."
