ABSTRACT
Chindadn bifaces are one of the few diagnostic lithic hallmarks of the terminal Pleistocene in interior Alaska. This paper presents the first regional overview and quantitative technological analysis of bifaces from archaeological sites dating 11,400 calendar years ago and earlier, based on characteristics of reduction, shaping, use, and discard. Overall, finished bifaces are small and extremely thin, with evidence of expedient production and use. Four basal-shape groups are present, falling semi-consistently into four descriptions. Convex-based bifaces appear as a distinct group with teardrop outline, informal reduction techniques, and minimal evidence for utilization. Triangular and subtriangular bifaces, exhibiting diverse reduction characteristics and low rates of hafting wear and breakage, appear to be more generalized point tips designed to conserve raw materials in Beringian climates. Concave-based bifaces show intensive flaking and high rates of haft-element breakage and abrasion, indicating they do not fit within a strict definition of Chindadn biface technology.
Acknowledgements
All work at Healy Lake has been conducted in consultation with the Healy Lake Working Group and would not have been possible without support from Dr. John P. Cook, Thomas E. Gillispie, Robert Sattler, and the Tanana Chiefs Conference. As a mentor to Younie, Tom Gillispie reviewed drafts and volunteered ideas during many long talks, especially about the mechanics and construction of projectile technology. The majority of the sample items was accessed in consultation with the University of Alaska Museum of the North. More recently excavated bifaces were assessed with the aid of Kelly Graf, Charles Holmes, and David Yesner in their research laboratories, and we thank them for their hospitality as well as their shared ideas and insights into Chindadn technology. The authors also thank the editors of the special issue in which this paper appeared (Ashley Smallwood and Heather Smith), as well as the anonymous reviewers who provided important, thoughtful critiques.

Notes
1 Gomez Coutouly (Citation2017) noted that there are two obsidian points from Swan Point CZ3. One is a convex-based Chindadn point that he re-assembled from three fragments, and the other is a non-diagnostic tip fragment (Gomez Coutouly, pers. commun., 2023).
