Chaco Culture National Historical Park

Chaco Culture National Historical Park is a United States National Historical Park hosting the densest and most exceptional concentration of pueblos in the American Southwest. 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 United States' most important pre-Columbian cultural and historical areas.

Between AD 900 and 1150, Chaco Canyon was a major center of culture for the Ancient Pueblo Peoples. Chacoans quarried sandstone blocks and hauled timber from great distances, assembling fifteen major complexes that remained the largest buildings 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.

New Mexico

New Mexico (Spanish: Nuevo México [ˈnweβo ˈmexiko]; Navajo: Yootó Hahoodzo [jo:tó haho:dzo]) is a state located in the southwestern region of the United States. It was admitted to the union as the 47th state on January 6, 1912. It is usually considered one of the Mountain States. New Mexico is the fifth-most extensive, the 36th-most populous, and the sixth-least densely populated of the 50 United States.

Inhabited by indigenous peoples of the Americas for many centuries before European exploration, New Mexico was subsequently part of the Imperial Spanish viceroyalty of New Spain. Later, it was part of Mexico before becoming a U.S. territory and eventually a U.S. state. Among U.S. states, New Mexico has the highest percentage of Hispanics, including descendants of Spanish colonists who have lived in the area for more than 400 years. It also has the second-highest percentage of Native Americans after Alaska, and the fourth-highest total number of Native Americans after California, Oklahoma, and Arizona. The nations in the state consist of mostly Navajo, Pueblo, and Apache peoples. As a result, the demographics and culture of the state are unique for their strong Hispanic and Native American influences, both of which are reflected in the state flag. The scarlet and gold colors of the New Mexico flag are taken from the royal standards of Spain, along with the ancient sun symbol of the Zia, a Pueblo-related tribe.

Canyon

A gorge or canyon (cañon, old spelling occasionally still used) is a deep ravine between pairs of escarpments or cliffs and is the most often carved landscape by the erosive activity of a river over geologic timescales. Rivers have a natural tendency to cut through underlying surfaces so will eventually wear away rock layers to lessen their own pitch slowing their waters; given enough time, their bottoms will gradually reach a baseline elevation—which is the same elevation as the body of water it will eventually drain into. This action, when the river source and mouth are at much different base elevations will form a canyon, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering.

A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually a river or stream and erosion carve out such splits between mountains. Examples of mountain-type canyons are Provo Canyon in Utah or Yosemite National Park in California's Sierra Nevada. Canyons within mountains, or gorges that have an opening on only one side are called box canyons. Slot canyons are very narrow canyons, often with smooth walls.

Pre-Columbian era

The pre-Columbian era incorporates all period subdivisions in the history and prehistory of the Americas before the appearance of significant European influences on the American continents, spanning the time of the original settlement in the Upper Paleolithic period to European colonization during the Early Modern period.

While the phrase "pre-Columbian era" literally refers only to the time preceding Christopher Columbus's voyages of 1492, in practice the phrase usually is used to denote the entire history of indigenous Americas cultures until those cultures were significantly influenced by Europeans, even if this happened decades or centuries after Columbus's first landing. For this reason the alternative terms of Precontact Americas, Pre-Colonial Americas or Prehistoric Americas are also in use. In areas of Latin America the term usually used is Pre-Hispanic.

Many pre-Columbian civilizations established hallmarks which included permanent settlements, cities, agriculture, civic and monumental architecture, major earthworks, and complex societal hierarchies. Some of these civilizations had long faded by the time of the first permanent European and African arrivals (c. late 15th–early 16th centuries), and are known only through archaeological investigations and oral history. Other civilizations were contemporary with the colonial period and were described in European historical accounts of the time. A few, such as the Maya civilization, had their own written records. Because many Christian Europeans of the time viewed such texts as heretical, men like Diego de Landa destroyed many texts in pyres, even while seeking to preserve native histories. Only a few hidden documents have survived in their original languages, while others were transcribed or dictated into Spanish, giving modern historians glimpses of ancient culture and knowledge.
