- Comments
- FlUa-4, Bluejackets Creek: Extensive shell midden deposits 0.3-2.4 m deep. The assemblage includes retouched basalt flakes, large crude pebble choppers, boulder spall scrapers, various pecked and ground-stone artifacts, abrasive stones, ground slate, and worked bone. The latter appear to correlate with middle to late periods of the Prince Rupert Harbour sequence (MacDonald 1969). S-676 is an acceptable date. Sutherland comments on S-935 and S-936 that the results agree with previous dates. She considers the dates on human bones to be somewhat too early, possibly due to contamination from white glue used to harden the bones for removal from the site. Chisholm (1986: 144) reports 13C ratios for six burials from this site, three of them dated. The latter three dates are normalized with their measured ratios. Among the six ratios, two are outliers in relation to the whole coastal region, and the other four yield an average ratio of -14.4 parts per mil (Chisholm, 1986: 104).
