Chronology, Culture, and Climate: A Radiometric Re-evaluation of Late Prehistoric Occupations at Cape Denbigh, Alaska
Bibliographic record
Abstract
This paper presents new data about the chronological placement of two archaeological sites at Cape Denbigh, Norton Sound, Alaska and others along the Kobuk River, Alaska.Direct radiometric dates on arrowpoints and harpoon heads indicate that selected type specimens are not always reliable temporal indicators for late prehistoric sequences in northwest Alaska and Arctic Canada.In the future new fieldwork and direct dating of artifacts and associated sediments will be necessary in order to refine culture-history sequences, evaluate the utility of artifact types as chronological indicators, and to examine the relationship between past culture change and environmental change in coastal Alaska. The Kobuk River Sequence and the Arctic Woodland CultureIn 1952 J. Louis Giddings published the results of his 1941 and 1947 archaeological and dendrochronological investigations along the Kobuk River (see Nash 2000 for a summary).Although he located over 24 archaeological sites, and reported

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
