- Comments
- DgRs-2, Tsawwassen: The excavaters distinguish seven zones (A-G), each with its own stratigraphic and cultural sequence. R. Brolly (p.c. 1999) examined the reports from the Beta laboratory and confirmed that the dates on human bones are uncorrected ages. These must be normalized by adding at least 100 years to the mean, but they cannot be precisely corrected for isotopic fractionation in the absence of measured C-13 ratios.
