A Light In The Dark: Luminescence Dating Intermountain Ware Ceramics From Four Archaeological Sites In Northwestern Wyoming, Carlie J. Ideker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The chronology of high-altitude archaeological sites in northwestern Wyoming is poorly understood due to limited reliable age constraints. While temporally diagnostic artifacts provide relative age control, fluctuations in atmospheric radiocarbon produce radiocarbon age results with multiple calibrated age-range intercepts that prove difficult to interpret. Age overestimates associated with the 'old wood' problem can be especially prominent at high-altitude sites where cold and semi-arid environments promote the presence of long-living trees and prolong the preservation of organic material. Moreover, regional droughts coupled with a pine beetle epidemic have resulted in increasing wildfire frequency and intensities that serve both as a benefit …
