Pushing Boundaries in Southwestern Archaeology draws together the proceedings from the sixteenth biennial Southwest Symposium. In exploring the conference theme, contributors consider topics ranging from the resuscitation of archaeomagnetic dating to the issue of Athapaskan origins, from collections-based studies of social identity, foodways, and obsidian trade to the origins of a rock art tradition and the challenges of a deeply buried archaeological record. The first of the volume’s four sections examines the status, history, and prospects of Bears Ears National Monument, the broader regulatory and political boundaries that complicate the nature and integrity of the archaeological record, and the cultural contexts and legal stakes of archaeological inquiry. The second section focuses on chronological “big data” in the context of pre-Columbian history and the potential and limits of what can be empirically derived from chronometric analysis of the past. The chapters in the third section advocate for advancing collections-based research, focusing on the vast and often untapped research potential of archives, previously excavated museum collections, and legacy data. The final section examines the permeable boundaries involved in Plains-Pueblo interactions, obvious in the archaeological record but long in need of analysis, interpretation, and explanation.

Since the 1960s, large-scale cultural resource management projects have revealed the former presence of extensive and varied Basketmaker III populations across the entire northern Southwest. These discoveries have resulted in a greatly expanded view of the BMIII period (A.D. 550-750) which immediately proceeds the Pueblo phase. Particularly noteworthy are findings of Basketmaker remains under those of later periods and in sites with open settings, as opposed to the more classic Basketmaker cave and rock shelter sites. Foundations of Anasazi Culture explores this new evidence in search of further understanding of Anasazi development. Several chapters address the BMII-BMIII transition, including the initial production and use of pottery, greater reliance on agriculture, and the construction of increasingly elaborate structures. Other chapters move beyond the transitional period to discuss key elements of the Anasazi lifeway, including the use of gray-, red-, and white-ware ceramics, pit structures, storage cists, surface rooms, full dependence on agriculture, and varying degrees of social specialization and differentiation. A number of contributions address one or more of these issues as they occur at specific sites. Other contributors consider the material culture of the period in terms of common elements in architecture, ceramics, lithic technology, and decorative media. This major synthesis of recent work on BMIII sites on the Colorado Plateau will be useful to anyone with an interest in the earliest days of Anasazi civilization.
