Variability In The Debitage Of The Early Holocene Lithic Assemblages Of The Sanders (45kt315) Site, Alexis Dyson
Variability In The Debitage Of The Early Holocene Lithic Assemblages Of The Sanders (45kt315) Site, Alexis Dyson
All Master's Theses
This thesis applies an analytic strategy based on a Darwinian evolutionary theoretical framework to measure variation in the cost and performance of stone tool manufacture and use at the Sanders (45KT315) site over time. Using this model, this thesis identified the selective conditions present in the technological organization of stone tool assemblages at the Sanders site. These conditions were identified by measuring variability in the debitage using mutually exclusive paradigmatic classifications. The classifications measure technological, functional, and raw tool stone material property dimensions. This thesis identifies the extent that debitage could be used to address variability between the Lower Lithic …
Paleoflood Record Reconstruction At An Archaeological Site On The Owyhee River, Southeastern Oregon, Stephanie Louise Vandal
Paleoflood Record Reconstruction At An Archaeological Site On The Owyhee River, Southeastern Oregon, Stephanie Louise Vandal
All Master's Theses
The magnitude and frequency of late Holocene floods on the Owyhee River in southeastern Oregon were reconstructed from fine-grained flood deposits at three sites in the river canyon. The stratigraphy at the Birch Creek study site (BCSS) preserves a record of seven to nine large floods from the last 2800 years. Two additional study sites, the Iron Gate and Waterwheel, within a 5-km reach of the BCSS, showed 18-26 floods from the late Holocene to 1993 A.D. and 17-22 floods from 8600 B.P. to 1993 A.D., respectively. Hydrologic Engineering Center-River Analysis System modeling of the 1993 flood and several paleofloods …
