Abstract

The Tyron Creek assemblage (Hells Canyon) is curated under an agreement with the USFS. The author continues to collaborate with Hackenberger and students to manage and study the collection. A reexamination of the type and distribution of point types confirm the diversity present in dart and arrow size points. Stratigraphic and activity area analysis of House 2 (500-1500 B.P.) illustrate the correspondence of types, which may reflect behavioral mutualism. Metric analysis of four forms represented in an overall sample of 126 points indicate an expected spread of sizes in arrow points. Twenty-six points were selected based on completeness for metric analysis. Corner-Notched points (n=100) dominate in all levels of the house, although Basal-Notched points are common (n=16). Side-Notched points (n=8) also occur in all occupation zones/levels. Nine lithic sources are represented, and both Chalcedony and Chert/Jasper are heat-treated. Red-Glassy Basalt is locally available and common. Obsidian is surprisingly rare given the relative proximity of the Timber Butte source (approx. 400 km).
