Les pentes raides de la vallée de la rivière du nord – Étude de versants-échantillons
Bibliographic record
Abstract
The author recently made a detailed investigation of the talus accumulations which mantle the steep slopes of the valley of the rivière du Nord, in the Laurentide hills, 45 miles north of Montréal, Québec. In postglacial times the lower section of the valley was occupied by an arm of the Champlain sea, and thick deposits of sand and clay were laid down in this estuary. The writer describes the various types of contacts which exist between the Champlain sea deposits and the talus accumulations — for example, certain talus slopes were completely covered by marine sediments and remain « fossilized » ; others have been stripped of their cover of unconsolidated materials and are consequently described as « exhumed ». The writer has also attempted to distinguish between those talus accumulations which antedate the Champlain incursion and those which postdate it. Most of the talus slopes appear to have formed immediately prior to or during the Champlain period, but a few have developed, at least in part, since that time. Frost-shattering (gelifraction) is the principal process contributing to the formation of these talus accumulations at the present time, although landslides also play an important role. The writer wonders whether these talus slopes of the valley of the rivière du Nord should not be classified as periglacial landforms.

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.
