L’évolution du lac proglaciaire Memphrémagog, sud du Québec
Bibliographic record
Abstract
Lors de la déglaciation finale des Appalaches, le lac proglaciaire Memphremagog a inondé les vallées situées immédiatement à l'est des monts Sutton. Le lac a d'abord occupé le nord du Vermont, tout près de la frontière internationale. Il a ensuite envahi, au Québec, les vallées du lac Memphrémagog actuel, de la rivière Missisquoi et, enfin, du Saint-François. Une étude détaillée des dépôts sur le versant est du bassin du Memphrémagog permet de reconstituer l'évolution du lac proglaciaire et, par conséquent, celle du retrait glaciaire. Huit phases lacustres se sont succédé entre les altitudes de 365 m et 165 m. L'une d'elles, la phase Va, contribue à redéfinir la position du front associé à la moraine de Cherry-River. Au cours de cette évolution, la déglaciation s'est faite de deux manières. Durant les phases I à Va, la glace, encore active, formait un lobe appuyé sur le versant est. Par la suite, le front a reculé plus au nord; la glace est devenue stagnante et s'est morcellée, isolant ainsi de petites calottes dans les vallées du lac Magog et de la rivière Massawippi.

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.
