Ancestral Puebloans in the context of "Zion National Park"

Utah is a landlocked state in the Mountain West subregion of the Western United States. It is one of the Four Corners states, sharing a border with Arizona, Colorado, and New Mexico. It also borders Wyoming to the northeast, Idaho to the north, and Nevada to the west. In comparison to all the U.S. states and territories, Utah, with a population of just over three million, is the 13th-largest by area, the 30th-most populous, and the 11th-least densely populated. Urban development is mostly concentrated in two regions: the Wasatch Front in the north-central part of the state, which includes the state capital, Salt Lake City, and is home to roughly two-thirds of the population; and Washington County in the southwest, which has approximately 180,000 residents. Most of the western half of Utah lies in the Great Basin.

Utah has been inhabited for thousands of years by various indigenous groups, such as the ancient Puebloans, the Navajo, and the Ute. The first Europeans to arrive – in the mid-16th century – were the Spanish. Because of the region's challenging geography and harsh climate, it only became a peripheral part of New Spain (and later of Mexico). Even while it was Mexican territory, many of the Utah region's earliest European settlers were from the United States; notable among these were Mormons who were fleeing marginalization and persecution in the United States and arrived via the so-called Mormon Trail. In 1848, after the Mexican–American War, the region was annexed by the U.S., becoming part of the Utah Territory, which included what later became Colorado and Nevada. Disputes between the dominant Mormon community and the federal government delayed Utah's admission as a state: in 1896, after it agreed to outlaw polygamy, it was admitted as the 45th state.

The Pecos Classification is a chronological division of all known Ancestral Puebloans into periods based on changes in architecture, art, pottery, and cultural remains. The original classification dates back to consensus reached at a 1927 archæological conference held in Pecos, New Mexico, which was organized by the United States archaeologist Alfred V. Kidder.

The Pueblo peoples or Puebloans are Native Americans in the Southwestern United States who share common agricultural, material, and religious practices. Among the currently inhabited pueblos, Taos, San Ildefonso, Acoma, Zuni, and Hopi are some of the most commonly known. Pueblo people speak languages from four different language families, and each pueblo is further divided culturally by kinship systems and agricultural practices, although all cultivate varieties of corn (maize).

Pueblo peoples have lived in the American Southwest for millennia and descend from the Ancestral Pueblo peoples. The term Anasazi is sometimes used to refer to Ancestral Puebloan. "Anasazi" is a Navajo adoption of a Ute term that translates to Ancient Enemy or Primitive Enemy, but was used by them to mean something like "barbarian" or "savage", hence the modern Pueblo peoples' rejection of it (see exonym).

Mesa Verde National Park is a national park of the United States and UNESCO World Heritage Site located in Montezuma County, Colorado, and the only World Heritage Site in Colorado. The park protects some of the best-preserved Ancestral Puebloan ancestral sites in the United States.

Established by Congress and President Theodore Roosevelt in 1906, the park occupies 52,485 acres (212 km) near the Four Corners region of the American Southwest. With more than 5,000 sites, including 600 cliff dwellings, it is the largest archaeological preserve in the United States. Mesa Verde (Spanish for "green table", or more specifically "green table mountain") is best known for structures such as Cliff Palace, one of the largest cliff dwellings in North America.

Chaco Culture National Historical Park is a United States National Historical Park in the American Southwest hosting a large concentration of pre-Columbian indigenous ruins of pueblos. The park is located in northwestern New Mexico, between Albuquerque and Farmington, in a remote canyon cut by the Chaco Wash. Containing the most sweeping collection of ancient ruins north of Mexico, the park preserves one of the most important cultural and historical areas in the United States.

Between AD 900 and 1150, Chaco Canyon was a major cultural center for the Ancestral Puebloans. Chacoans quarried sandstone blocks and hauled timber from great distances, assembling fifteen major complexes that remained the largest buildings ever built in North America until the 19th century. Evidence of archaeoastronomy at Chaco has been proposed, with the "Sun Dagger" petroglyph at Fajada Butte a popular example. Many Chacoan buildings may have been aligned to capture the solar and lunar cycles, requiring generations of astronomical observations and centuries of skillfully coordinated construction. Climate change is thought to have led to the emigration of Chacoans and the eventual abandonment of the canyon, beginning with a fifty-year drought commencing in 1130.

Canyon de Chelly National Monument (/dəˈʃeɪ/ də-SHAY) was established on April 1, 1931, as a unit of the National Park Service. Located in northeastern Arizona, it is within the boundaries of the Navajo Nation and lies in the Four Corners region. Reflecting one of the longest continuously inhabited landscapes of North America, it preserves ruins of the indigenous tribes that lived in the area, from the Ancestral Puebloans to the Navajo. The monument covers 83,840 acres (131 sq mi; 339 km) and encompasses the floors and rims of the three major canyons: de Chelly, del Muerto, and Monument. These canyons were cut by streams with headwaters in the Chuska Mountains just to the east of the monument. None of the land is federally owned. Canyon de Chelly is one of the most visited national monuments in the United States.

Cliff Palace is the largest cliff dwelling in North America. The structure built by the Ancestral Puebloans is located in Mesa Verde National Park in their former homeland region. The cliff dwelling and park are in Montezuma County, in the southwestern corner of Colorado, Southwestern United States.

Hovenweep National Monument is located on land in southwestern Colorado and southeastern Utah, between Cortez, Colorado and Blanding, Utah on the Cajon Mesa of the Great Sage Plain. Shallow tributaries run through the wide and deep canyons into the San Juan River.

Although Hovenweep National Monument is largely known for the six groups of Ancestral Puebloan villages and its kiva, there is evidence of occupation by hunter-gatherers from 8,000 to 6,000 B.C. until about AD 200. Later, a succession of early puebloan cultures settled in the area and remained until the 14th century.
