EA-IRMS and the isotope ecology from faunal remains at the Slocan Narrows site, Upper Columbia River area, interior Pacific Northwest

Summary

Isotope ecological signatures can add to the overall understanding of terrestrial and aquatic species’ diets that are present at an archaeological site. In this paper we analyze fauna specimens from across the breadth of species found at the Slocan Narrows site, an aboriginal pithouse village occupied from 3,100 cal BP to the late 18th century in the Upper Columbia River area of the interior Pacific Northwest. We utilize EA-IRMS to measure δN, δC, and δO isotope ratios to obtain an understanding of the dietary ecological landscape of the local habitat at Slocan Narrows. Fauna specimens used in this study come from well documented pithouses dating to 1065 cal BP, 533 cal BP, and 405 cal BP, providing a temporal examination of the isotope ecology of the site through the later phases of the village occupation.
