The Early Holocene-aged Component at the Jay Creek Ridge Site, Middle Susitna River Valley, Alaska

ABSTRACT The Jay Creek Ridge site is an early Holocene stratified site located in the Middle Susitna River Valley in central Alaska. Two components, the Lower and Upper, were defined through several years of testing and excavation in the 1980s (1982–1983 and 1986). Accelerator mass spectrometry dating of the Lower Component indicates the site is around 11,000 calibrated years before present, placing it among the oldest upland sites in the central Alaska Range.
