Provenance and 3D Geometric Morphometry of a Large Obsidian Biface Cache from Central Oregon—Preliminary Perspectives

Summary

This is an abstract from the "SAA 2024: Individual Abstracts" session, at the 89th annual meeting of the Society for American Archaeology.

Caches of stone tools offer unique opportunities to study lithic technology crafting at extremely short temporal scales. We created digital 3D models of 378 obsidian bifaces from a cache located in central Oregon (35DS751) and submitted them for x-ray fluorescence and geometric lithic morphometric research (GLiMR) analyses. The raw materials from this cache were from local eruptive sources. In this poster, we explore ways in which 3D scanning and geometric morphometry can be used to extend traditional lithic tool studies of technological design and lithic production sequences.
