Comments
AdHa-1, Varden: Isotopic corrections for the RIDDL dates were based on the assumption of a 13C ratio of -25 +/- 2 parts per mil. Ten samples of pottery encrustations were analyzed for their 13C ratios by H. Schwarcz, McMaster University, who found an average ratio of -23.77 per mil (overall range -22.22 to -26.15 per mil). Three of these samples were also dated by RIDDL, and these had ratios averaging 24.46 per mil (overall range -23.04 to -25.79 per mil). These results show good agreement with the ratio assumed by RIDDL, and they suggest that C4 plants did not contribute to the encrustations. See MacDonald (1986: 19-20) for detailed discussion of the dates. Cooper and Savage (1994: 99) summarize the faunal assemblages from this seasonal fishing station. Still's floated sample was dominated by fish bone, 90% of it representing burbot. The surface collection examined by Prevec had higher proportions of bird, reptile, and mammal bone. The site was probably occupied in early spring, principally to obtain the night-spawning burbot, possibly for its oil. Still determined the season of occupation not only from the species present but also by examining fish scales. Artifacts include five bone awl tips.
