We were able to run a pair of C14 dates on materials from Deering as part of the WALRUS project. I just got the results back today. I have to share the calibrated dates with the folks in Deering first. They were kind enough to let me include the samples, which were found during the monitoring work we did there late last summer, in the WALRUS studies.
They were found together in a fairly thin organic layer (likely midden) in the wall of one of the trenches. Very little walrus has been found there, so we were lucky.
