Third Thursday Food for Thought Presentation – “An Embarrassment of Riches: Tree-Ring Dating and the (Mis-)Interpretation of Southwestern Archaeology”

August 15 @ 7:00 pm - 8:30 pm

On Thursday, August 15, 2024, join Old Pueblo Archaeology Center’s “Third Thursday Food for Thought” Zoom online program featuring the presentation “An Embarrassment of Riches: Tree-Ring Dating and the (Mis-)Interpretation of Southwestern Archaeology” by archaeologist Stephen E. Nash, PhD. This free online presentation will be held from 7:00-8:00 p.m. (ARIZONA/Mountain Standard Time – (same as Pacific Daylight Time).

In December 1929, National Geographic Magazine published new tree-ring dates for a small, select group of archaeological sites in the American Southwest. For the first time ever, archaeologists then knew how old those sites actually were, but the annually resolved dates often proved difficult to interpret when compared to other archaeological data, which cannot be as finely resolved with respect to dating and time.  Ever since then, however, southwestern archaeologists have been blessed with an incredibly rich, and still growing, database of calendar-year tree-ring dates to guide their analyses. Unfortunately, our interpretations often play fast and loose with the underlying data, and our interpretations may not be as reasonable as we might think. In this presentation, Dr. Stephen E. Nash will examine the history of southwestern archaeological tree-ring dating to explore what might, or might not, be reasonable to infer from large sets of tree-ring dates.
