A Comparison of Changing Reduction Sequences of Obsidian from the Grandad Site in the Central Sierra, California

Summary

This is an abstract from the "SAA 2023: Individual Abstracts" session, at the 88th annual meeting of the Society for American Archaeology.

This is an investigation of obsidian chipping waste from the Grandad site, located in the Central Sierra near Mariposa, California based on point types found in deposits that have shown evidence of continuous occupation from 9000 BP to European contact. We searched for evidence of a changing reduction sequence from biface blank characteristics of large dart points to a flake-based reduction sequence characteristic of arrow points. We also examined the changing amounts of cortex on the obsidian flakes with depths that may reflect changes in how the obsidian arrived at the site.
