Pueblo Bonito
From Wikipedia, the free encyclopedia
Pueblo Bonito, the largest and best known Great House in Chaco Culture National Historical Park, northern New Mexico, was built by ancestral Pueblo people and occupied between AD 828 and 1126.
In January 1941, a section of the canyon wall known as Threatening Rock, or tse biyaa anii'ahi (leaning rock gap) in Navajo, collapsed, destroying some of the structure's rear wall and a number of rooms. The builders of Pueblo Bonito appear to have been well aware of this threat. However, they chose to build beneath the fractured stone, which stood 97 feet high and weighed approximately 30,000 tons, and compensated by building a structural reinforcement for the slab.

[edit] Discovery
U.S. army Lt. James H. Simpson and Carravahal, Simpson's guide from San Juan Pueblo, first came upon Chaco Canyon during a 1849 military expedition. They briefly examined eight larger ruins in Chaco Canyon including Pueblo Bonito, named pretty village in Spanish by Carravahal. At the conclusion of his expedition, Simpson published the first description of Chaco Canyon in his military report, with drawings by expedition artist R. H. Kern.
Rancher Richard Wetherill, and natural history student George H. Pepper from the American Museum of Natural History, began excavations at Pueblo Bonito in 1896 and ended in 1900. These excavations were financed by B. Talbot Hyde and Frederick E. Hyde, Jr. of New York City, who were philanthropists and collectors. During this time, the two men uncovered 190 rooms and photographed and mapped all major structures in the canyon. The Hydes donated the resulting large collection of artifacts to the American Museum of Natural History. After the excavation, Wetherill sought to gain personal control of parts of Chaco Canyon, including Pueblo Bonito, Chettro Kettle and Pueblo Del Arroyo. He filed a homestead entry on these ruins, which was invalidated by the General Land Office in 1904 when the federal government took formal possession of these lands. Wetherill was required to stop his ongoing excavations on federal property, but continued to run a trading post at Chaco Canyon until his death in 1910.
[edit] Description
Pueblo Bonito is divided into two sections by a precisely aligned wall, running north to south, through the central plaza. A Great Kiva is placed on either side of the wall, creating a symmetrical pattern common to many of the Great Houses. In addition to the great kivas, over thirty other kivas or ceremonial structures have been found, many also associated with the large central courtyard. Interior living spaces were quite large by the standards of the Ancient Pueblo.
The site covers almost two acres (8,000 m²) and incorporates at least 650 rooms, with some estimates rising to 800. In parts of the village, the tiered structure was four and five stories high. During later construction, some lower level rooms were filled with debris to better support the weight of the upper levels. The builder's use of core and veneer architecture and multi-story construction produced massive masonry walls as much as three feet (1 meter) thick.
Archaeologists' population estimates for the village have varied. During the early 20th century, the structures were viewed as small cities, with people residing in every room. From this perspective, Pueblo Bonito could have accommodated several thousand inhabitants at the village's peak. More recent analysis has lowered the resident total to less than 800, primarily due to the small number of usable hearths in the ruins. These tend to be located on the ground floor, near the central plaza, and are associated with entrances to a series of rooms going deeper into the structure. Rooms were connected by a series of interior doorways, some of them in a T-shape. A family may have inhabited 3 to 4 rooms, with many small interior spaces being used for storage. There was generally no outside access to the room blocks other than from the central courtyard.
[edit] Rock art
Behind Pueblo Bonito is a series of petroglyphs depicting six-toed feet, an element also found in other Ancient Pueblo rock art. These images were made in the late 900s or early 1000s.
