- Comments
- KdDq-7, Tanfield: This is a midden, 46-53 cm deep, all but the top 10 cm below the sod permanently frozen. It covers an estimated 102 sq m of which 7.5 sq m was excavated. There were no apparent stratigraphic layers, and the midden apparently represents a brief occupation. From its elevation and artifact typology it belongs early in the Dorset sequence. Maxwell notes that the interpretation of this site has been problematical. He considered M-1528 to be 200-350 years too late but suggested that an average of its result with that of P-698 on the same sample yielded a satisfactory age. By the time GSC-820 was submitted, he had concluded that Tanfield was coeval with one of the Nanook site components but differed in season of occupation, Tanfield in the summer, Nanook in late autumn and winter. GaK-1280, from the earliest part of the midden, should have been earlier than P-698, and contamination was suspected. Note, however, that GaK-1280 dated terrestrial carbon, and all of the other samples are from marine organisms.
