Precontact Native Copper Innovation in British Columbia
Bibliographic record
Abstract
Copper has figured prominently in discussions of social complexity among Northwest Coast Cultures. Coppers, shield-like sheets of copper variable in size, were a form of lineage wealth displayed, gifted, or ritually destroyed at potlatches; and copper artifacts have been recovered from human burials. The former use of copper is well-documented ethnographically and historically while the latter phenomenon is less well understood. This paper provides an overview of the occurrence of copper in precontact archaeological contexts in British Columbia using published and unpublished literature. Our investigation is framed within a Behavioral Archaeology approach that elicits ideas on copper innovation and all that it entailed. We find that copper is rare in precontact contexts from a province-wide perspective; there was likely more than one instance of native copper innovation; and contrary to previous suggestions, the copper-rich Dene region of south-central Alaska and southwestern Yukon cannot account for most of the precontact examples of copper use in the province. We offer some hypotheses to explain the precontact distribution of copper in BC, including both local invention and diffusion, not in an attempt to deliver the final verdict on this topic, but rather, to stimulate additional research.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
