This is an abstract from the "Research, Education, and American Indian Partnerships at the Crow Canyon Archaeological Center" session, at the 88th annual meeting of the Society for American Archaeology. The initial 40 years of research conducted by the Crow Canyon Archaeological Center included several excavation projects that focused on a primary stated research goal of the center: discover why Pueblo peoples completely and permanently vacated the northern San Juan region late in the...
"Tiwanaku VI" revisited: Postcolonialism and Ethnogenesis in the middle Moquegua Valley Province (2015)
The Middle Moquegua Valley was home to between 10,000 and 20,000 Tiwanaku colonists during the Tiwanaku IV and V periods. This paper examines what became of these populations in Tiwanaku’s postcolonial period. Three decades ago, the name "Tiwanaku VI" was briefly proposed to describe Moquegua’s diverse "post-expansive" ceramic styles. Subsequent full coverage survey in the and excavations in the middle valley indicate that after Tiwanaku V settlements, temple, and cemeteries were largely...
Tradition and Transformation during the Middle Horizon to LIP Transition: Visual and Compositional Analyses of Tumilaca and Estuquiña Pottery in the Moquegua Valley, Peru (2018)
In many Andean regions, the shift from the Middle Horizon to the Late Intermediate Period, or LIP, is archaeologically identified by stylistic changes. In the Moquegua valley, southern Peru, LIP (ca. AD 1250-1476) Estuquiña architecture and portable material culture is starkly different from that associated with terminal Middle Horizon (ca. AD 950-1200) Tumilaca populations. Until recently Tumilaca settlements were thought to have been completely abandoned prior to the appearance of Estuquiña...
Transformation and Continuity: Late Tiwanaku to Post Tiwanaku traditions in the Central Valley of Cochabamba (2015)
This paper presents evidence from the Central Valley of Cochabamba, a key peripheral region of the Tiwanaku state. It addresses Tiwanaku expansion, state collapse and post-Tiwanaku transformation and continuity using data from ceramic styles and other material culture traditions. Also presented are new radio-carbon dates from the Central Valley site of Piñami covering Tiwanaku expansion and collapse and how these dates fit into the larger regional context and suggest that Tiwanaku influence...
Transition and Resilience: Commoner Occupation in the Rio Amarillo East Pocket of the Copan Valley during the Postclassic Period (2019)
This is an abstract from the "The Pre-Columbian Cultures of Honduras after AD 900" session, at the 84th annual meeting of the Society for American Archaeology. Recent and ongoing research at residential groups at the sites of Río Amarillo and Quebrada Piedras Negras is providing a better understanding of the lives of commoners and of the population dynamics during the latter part of the Late Classic through the Postclassic Period. These sites share the second-widest pocket of the Copan River...
Using Bayesian Radiocarbon Chronologies in Conjunction with Artifact Inventories to Reconstruct the Timing and Formation of Peri-abandonment Deposits at Baking Pot, Belize (2018)
A variety of functions have been proposed for ‘problematic deposits’ across the Maya lowlands. All of the explanations have archaeological and temporal implications that have rarely been operationalized together to gain better insights into the nature of these deposits. In this presentation, we describe these features as ‘peri-abandonment deposits’, as all proposed explanations imply that the events that led to the formation of the deposits occurred around the time (or after) ceremonial centers...
Variability among the Dead: Population Structure and Inferred Cultural Adaptations to the Changing Environmental and Sociopolitical Landscapes during the Late Moche (AD 650–800) Era in the Jequetepeque Valley, Peru (2018)
Recent bioarchaeological and archaeological research regarding the environmentally influenced demise of the Moche (AD 200 – 800) of the Jequetepeque Valley, Perú, indicates a variety of responses, including population dispersals, political fragmentation, cultural hybridization, and new political alliances with recently arrived foreigners at ceremonial centers. Biodistance analyses suggest that adjacent highland Cajamarca peoples from the adjacent highlands arrived in the Jequetepeque and likely...
Why did they leave? The Wari Withdrawal from Moquegua (2017)
In Moquegua the monumental provincial center of Cerro Baúl was ritually abandoned circa 1050CE. It is at this time that Wari affiliated occupation of the sacred summit ended and production of imperial Wari goods ceased in the region. This evidence does not indicate that the empire collapsed at this time, but instead suggests when Wari officials chose to withdraw from this frontier region. Why did they leave? In this paper we discuss the changing population dynamics in Moquegua at 1050CE and how...
Why the Chimu State of the Northern Coast of Peru Failed: Rapid Expansion Is Not Always Enough (2018)
In the last 1000 years before the arrival of the Spanish in 1532, the expansionist states of the Andean region of Peru—like those of the Old World--appear to have grown incrementally, flourished briefly, and disappeared. Despite intensive study in the 1970’s and since, the inner structure and dynamics of Chimor have eluded archaeologists because there is limited information from European observers and because there are many questions archaeologists have not yet addressed. At its maximum, Chimor...
