Transporting Timbers to Chaco Canyon
A total of 200,000+ large timbers were transported >75 km to Chaco Canyon, a political and religious center in the precontact U.S. Southwest, using only human power. Previous researchers reported that typical primary roof beams (vigas) of Chacoan Great Houses averaged 0.22 m in diameter and 5 m in length with a mass of 275 kg. However, the 275 kg mass appears to be a miscalculation. Here, we calculate that a ponderosa pine timber of the stated di…

The Curious Douglas-Fir (Pseudotsuga Menziesii) Trees in Schulman Grove, Mesa Verde National Park, Southwestern Colorado, USA
In 1954, archaeologists James Allen Lancaster and Don Watson and dendrochronologist Edmund Schulman asserted that a small grove of Douglas-fir (Pseudotsuga menziesii [Mirbel] Franco var. glauca [Beissener] Franco) trees in Navajo Canyon on the west side of Chapin Mesa in Mesa Verde National Park contained evidence of stone-axe-cut tree limbs. In 1965, archaeologists Robert Nichols and David Smith published an article entitled 'Evidence of Prehist…
Convergence of Evidence Supports a Chuska Mountains Origin for the Plaza Tree of Pueblo Bonito, Chaco Canyon
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 origi…

Reflections On the Foundation, Persistence, and Growth of the Laboratory of Tree-Ring Research, Circa 1930–1960
On the occasion of the 75th anniversary of the Laboratory of Tree-Ring Research, it is appropriate to reflect on the origin of the LTRR and the oft overlooked early period of its history. The period from the “Bridging the gap” event in 1929 to the semi-retirement of A.E. Douglass in 1958 was a crucial time in the development of the LTRR. Although this paper focuses on the history of the LTRR between those events, at points the history of the LTRR…

Chapter 4. Understanding Anasazi Culture Change Through Agent-Based Modeling
Mesa Verde Settlement History and Relocation
At the beginning of the thirteenth century A.D., the Mesa Verde region was densely inhabited by Ancestral Pueblo peoples. By the end of that century, Ancestral Pueblo peoples no longer permanently inhabited the region. We present detailed reconstructions of precipitation based on tree rings from five geographic subregions of Ancestral Pueblo occupation (Mesa Verde, Tsegi/Kayenta, Chama, Cibola, and Santa Fe) and a consideration of distributions o…

Population growth and collapse in a multiagent model of the Kayenta Anasazi in Long House Valley
Long House Valley in the Black Mesa area of northeastern Arizona (U.S.) was inhabited by the Kayenta Anasazi from about 1800 before Christ to about anno Domini 1300. These people were prehistoric ancestors of the modern Pueblo cultures of the Colorado Plateau. Paleoenvironmental research based on alluvial geomorphology, palynology, and dendroclimatology permits accurate quantitative reconstruction of annual fluctuations in potential agricultural …

Human Behavior, Demography, and Paleoenvironment on the Colorado Plateaus
Archaeological and paleoenvironmental data are integrated in an investigation of culture change among the Anasazi of the American Southwest by a conceptual model of the interaction among environment, population, and behavior, the major determinants of human adaptive systems. Geological, palynological, and dendrochronological reconstructions of low and high frequency environmental variability coupled with population trends are used to specify peri…
Prehistoric Long-Distance Transport of Construction Beams, Chaco Canyon, New Mexico
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 preh…

Environmental Characteristics of the a.d. 900–1300 Period in the Central Mesa Verde Region
This paper has a threefold purpose. First, it reviews environmental evidence proposed to account for the final migrations from the Northern San Juan region: the Great Drought (A.D. 1276–;1299), the advent of the Little Ice Age (ca. A.D. 1200), and a prolonged period of climatic irregularity that began in the thirteenth century (ca. A.D. 1250–;1450). Second, it characterizes environmental variability for the A.D. 900–;1300 interval. Finally, it su…
Evaluating Tree-Ring Interpretations at Walpi Pueblo, Arizona
The availability both of documentary data on the history of the Hopi pueblo of Walpi and of tree-ring dates from the village provides a rare opportunity to evaluate tree-ring interpretations in the light of independent chronological evidence. Three major events in the history of the community are reflected in the village's overall tree-ring date distribution: the initial settlement around A.D. 1400 of the site of Koechaptevela, located on the fla…

La 2298
Tree-ring dates from Tapacito Ruin (LA 2298), the earliest securely dated Navajo pueblito, have played a central role in the interpretation of the Gobernador phase of Navajo history. Although previous research provided general parameters for the site occupation, the lack of provenience data for many of the tree-ring specimens left several questions unanswered. Research conducted in 1990 confirms the early occupation of the pueblito and offers sug…
The Sheep and Goat Corral
The recent growth of interest in Navajo archaeology suffers from the lack of an analytical foundation comparable to that which structures research on the prehistoric populations of the Southwest. Observations on the data potential of the ubiquitous sheep and goat corral are offered as a contribution to the effort to develop such a basis for Navajo archaeology. These corrals provide information on site function, site chronology, duration of site u…

Desert Dendrochronology
Archaeological tree-ring dating in the Southwestern deserts has been thwarted by the absence of the conditions necessary for dendrochronological dating: the recovery from prehistoric sites of a sufficiently large number of potentially datable charcoal samples and the existence of local master tree- ring chronologies that extend back into the prehistoric period. Recent archaeological collection and tree-ring chronology building have altered this s…
The View From the North
I was asked to evaluate Mogollon from the perspective of the Colorado Plateau. Historically, Mogollon was disengaged from the original Basketmaker-Pueblo paradigm of Southwestern prehistory only with difficulty. In these days of Mogollon Conferences, we tend to forget that many eminent scholars vigorously resisted the concept of Mogollon. Many considered it to be Anasazi either diluted or enriched by contact with the Hohokam. Haury, Martin, and t…

Effects of Subject-Generated and Experimenter-Supplied Associations at Time of Storage on Free Recall of High and Low Verbal Associators
Undergraduates were classified on the basis of the average number of associations they could produce in response to a standard set of verbal units (associative ability). 28 high and 28 low associators instructed to make an association (subject-generated) to each verbal unit (CVCVC) of a list of to-be-recalled units did not differ in recall. High associators supplied with an association (experimenter-supplied) to each verbal unit of the same list …

The Colorado Plateaus: Cultural Dynamics and Paleoenvironment
Convergent archeological, geological, palynological, dendrochronological, and radiometric data provide a paleoenvironmental record for the American Southwest at a level of detail and time resolution not previously achieved. Many prehistoric cultural and demographic changes on the Colorado Plateaus coincided with environmental fluctuations defined by precisely dated geoclimatic and bioclimatic indicators. These coincidences support the interpretat…
