Lines Of Evidence

The iconic Plaza Tree of Pueblo Bonito is widely believed to have been a majestic pine standing in the west courtyard of the monumental great house during the peak of the Chaco Phenomenon (AD 850–1140). The ponderosa pine (Pinus ponderosa) log was discovered in 1924, and since then, it has been included in “birth” and “life” narratives of Pueblo Bonito, although these ideas have not been rigorously tested. We evaluate three potential growth origins of the tree (JPB-99): Pueblo Bonito, Chaco Canyon, or a distant mountain range. Based on converging lines of evidence—documentary records, strontium isotopes (87Sr/86Sr), and tree-ring provenance testing—we present a new origin for the Plaza Tree. It did not grow in Pueblo Bonito or even nearby in Chaco Canyon. Rather, JPB-99 originated from the Chuska Mountains, over 50 km west of Chaco Canyon. The tree was likely carried to Pueblo Bonito sometime between AD 1100 and 1130, although why it was left in the west courtyard, what it meant, and how it might have been used remain mysteries. The origin of the Plaza Tree of Pueblo Bonito underscores deep cultural and material ties between the Chaco Canyon great houses and the Chuska landscape.

AbstractMost recent attempts to understand the complex nature of the prehispanic occupation of Chaco Canyon in northwestern New Mexico often have postulated that the canyon was a center for pilgrimage fairs and ceremonies that attracted hundreds if not thousands of individuals from the surrounding region who may have resided in the canyon for significant periods of time. Scholars first proposed this model in the 1980s based on what they perceived as the unusual nature of Pueblo Alto, a Chacoan great house. In particular, they suggested that normal household activity and refuse disposal could not explain the deposition patterns in the Alto trash mound, the unusual number of ceramic vessels, and characteristics of the fauna recovered from the settlement. We evaluate this argument focusing primarily on the ceramic and faunal evidence and conclude that neither the ceramic nor the faunal data support the occurrence of periodic fairs, festivals, dances or pilgrimages of the scale that have been postulated.

Archaeogenomic studies of a burial crypt in Pueblo Bonito, Chaco Canyon, New Mexico, have demonstrated the presence of an elite matrilineal descent group that spanned most of the 300+ years the great house was occupied, confirming, among other things, the deep antiquity of matrilineal ideologies among the Ancestral Pueblos of the northern Southwest. This article explores the sociopolitical implications of matrilineal descent, matrilocal residence, and Iroquois-Crow alliance structures among the Ancestral Pueblos of Chaco and elsewhere. It argues that matrilineal ideologies helped shape community forms and intercommunity relations throughout the Pueblo Southwest. It argues further that kinship provides insights into Chaco's eleventh-century expansion that dispersed “outlier” great houses over much of the southeastern Colorado Plateau. The article concludes with a call for archaeologists and cultural historians to pay more attention to kinship, the principal idiom of social, economic, and political relations in nonstate societies.

Environmental Histories

Pollen analysis is frequently used to build climate and environmental histories. A distinct Holocene pollen series exists for Chaco Canyon, New Mexico. This study reports linear modeling and hypothesis testing of long distance dispersal pollen from radiocarbon-dated packrat middens which reveal strong relationships between piñon pine ( Pinus edulis) and ponderosa pine ( Pinus ponderosa). Ponderosa pollen dominates midden pollen assemblages during the early Holocene, while a rapid shift to a much higher proportion of piñon to ponderosa pine pollen between c. 5440 and 5102 cal. yr BP points to an aridization episode. This shift is associated with higher δ18O values in Southwest speleothem records relative to the preceding millennium. The period of aridization is followed by a sharp increase in El Niño/Southern Oscillation events that would have caused highly variable precipitation and lasted until c. 4200 cal. yr BP. Bayesian change-point analysis suggests that this aridization episode led to stable ecotonal boundaries for at least 3000 years. The piñon/ponderosa transition may have been caused by punctuated multiyear droughts, analogous to those in the 20th century. The earliest documented instance of Zea mays cultivation on the Colorado Plateau is around c. 3940 14C yr BP ( c. 4364 cal. yr BP) (Hall SA (2010) Early maize pollen from Chaco Canyon, New Mexico, USA. Palynology 34(1): 125–137) in Chaco Canyon. The introduction of this labor-intensive cultigen from Mesoamerica may have been facilitated by changes in the regional ecosystems, specifically by an increase in piñon trees, that promoted increasing human territoriality. Linear modeling and hypothesis testing can complement traditional palynological techniques by adding greater resolution in vegetation patterning to climate/environmental histories.

Common Era

An enduring mystery from the great houses of Chaco Canyon is the origin of more than 240,000 construction timbers. We evaluate probable timber procurement areas for seven great houses by applying tree-ring width-based sourcing to a set of 170 timbers. To our knowledge, this is the first use of tree rings to assess timber origins in the southwestern United States. We found that the Chuska and Zuni Mountains (>75 km distant) were the most likely sources, accounting for 70% of timbers. Most notably, procurement areas changed through time. Before 1020 Common Era (CE) nearly all timbers originated from the Zunis (a previously unrecognized source), but by 1060 CE the Chuskas eclipsed the Zuni area in total wood imports. This shift occurred at the onset of Chaco florescence in the 11th century, a time with substantial expansion of existing great houses and the addition of seven new great houses in the Chaco Core area. It also coincides with the proliferation of Chuskan stone tools and pottery in the archaeological record of Chaco Canyon, further underscoring the link between land use and occupation in the Chuska area and the peak of great house construction. Our findings, based on the most temporally specific and replicated evidence of Chacoan resource procurement obtained to date, corroborate the long-standing but recently challenged interpretation that large numbers of timbers were harvested and transported from distant mountain ranges to build the great houses at Chaco Canyon.

High-precision accelerator mass spectrometer (AMS) 14C dates of scarlet macaw (Ara macao) skeletal remains provide the first direct evidence from Chaco Canyon in northwestern New Mexico that these Neotropical birds were procured from Mesoamerica by Pueblo people as early as ∼A.D. 900–975. Chaco was a prominent prehistoric Pueblo center with a dense concentration of multistoried great houses constructed from the 9th through early 12th centuries. At the best known great house of Pueblo Bonito, unusual burial crypts and significant quantities of exotic and symbolically important materials, including scarlet macaws, turquoise, marine shell, and cacao, suggest societal complexity unprecedented elsewhere in the Puebloan world. Scarlet macaws are known markers of social and political status among the Pueblos. New AMS 14C-dated scarlet macaw remains from Pueblo Bonito demonstrate that these birds were acquired persistently from Mesoamerica between A.D. 900 and 1150. Most of the macaws date before the hypothesized apogeal Chacoan period (A.D. 1040–1110) to which they are commonly attributed. The 10th century acquisition of these birds is consistent with the hypothesis that more formalized status hierarchies developed with significant connections to Mesoamerica before the post-A.D. 1040 architectural florescence in Chaco Canyon.

Distance Transport

Identification of spruce (Picea) and fir (Abies) construction timbers at Chetro Ketl in Chaco Canyon, New Mexico, implies that between A.D. 1030 and 1120 the Anasazi transported thousands of logs more than 75 km. These timbers came from high elevations, probably in mountains to the south (Mt. Taylor) and west (Chuska Mountains) where Chacoan interaction was well established. Survey in these mountains might disclose material evidence of these prehistoric logging activities.
