- Title
THE OLD WOOD CALIBRATION PROJECT: NEW FINDINGS FOR EPHEMERAL COLORADO ARCHAEOLOGY.

- Abstract
The Old Wood Calibration Project (OWCP) focused on the archaeology of the Fremont in northwestern Colorado and the Utes of west-central Colorado. The project relied on the development and utilization of a new cutting-edge empirical methodology for mitigating the "old wood effect" (Schiffer 1982, 1986; Smiley and Ahlstrom 1998) in radiocarbon and tree-ring dating of ancient pinyon and juniper charcoal. The final report of the OWCP (Baker et al. 2023) has been completed and centers on this new methodology, which is widely applicable and combines both dendrochronology and radiocarbon dating, allowing for mitigation of the old wood problem in various environmental settings. This methodology allows one to overcome the old wood problem and derive correction factors which provide dates and ranges that are far more likely to encompass the date of the targeted archaeological event than those derived by simply radiocarbon dating old wood charcoal as commonly relied upon by archaeologists to determine the ages of components. The OWCP methodology was used to adjust some Fremont dates (ca. AD 800-1400) from the Douglas Creek Arch in northwestern Colorado and to replace early dates (ca. AD 1100) which had been proposed for the entry of the Utes into west-central Colorado.
