Prehistoric Intertidal Fish Traps from Central Southeast Alaska
Bibliographic record
Abstract
Quatre sites archeologiques situes dans la zone intertidale pres de Petersburg, au sud-est d'Alaska, sont decrits et compares ici afin d'elucider la fonction de ces sites et leur structures. Les sites de Sandy Beach, Woody Island, McDonald Arm, et Blind Slough contiennent des alignements de roches et de pieux en bois qui representent les restes d'engins de peche. Chaque structure inclut deux ailes qui guident le poisson vers un enclos circulaire ou cordiforme. Il est probable que plusieurs especes de poisson, incluant le saumon, ont ete exploites. Cette technologie fut utilisee pendant plusieurs siecles, entre 1300 et 2100 ans avant aujourd'hui. Des centaines de sites intertidaux avec des alignements de roches et de pieux en bois ont ete identifies dans les etats d'Oregon et Washington, en Colombie Britannique, et dans le sud-est d'Alaska, mais tres peu retiennent les vestiges d'un enclos ou parc. Les sites de Petersburg permettent une analyse plus detaille de la technologie de peche prehistorique dans l'aire culturelle de la Cote Nord-Ouest, et pourraient expliquer comment les alignements de roches et de pieux en bois fonctionnait dans les autres sites ou seulement les ailes sont preservees.

How this classification was reachedexpand
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.
