Reconnaissance surficial geology, Pelly Lake, Nunavut, NTS 66-F north
Bibliographic record
Abstract
Preliminary surficial geology studies, through aerial photograph interpretation and limited legacy data, were undertaken in the north half of the Pelly Lake map area. Widespread streamlined till blanket, hummocky till, till veneer and ridged till which may exhibit small transverse ridges locally, are common across the map area. Drumlinoids and crag-and-tails record a regional north-northwestward ice flow during the last glaciation, with local crosscutting age relationships. Rare morainal ridges indicate recessional or stagnant ice-marginal positions. Northward trending meltwater corridors consist of glaciofluvial sediments, zones of scoured bedrock, lags of till veneer and areas of ridged till. Isolated glacial lakes of variable extent were formed by ponding of meltwater, and some fine-grained glacial lake sediments are now characterized by shallow thermokarst lakes. Previous levels of Pelly and Garry lakes are estimated on ice-contact deltas at 190-200 m a.s.l. Active eolian activity can occur adjacent to rivers and lakes, associated with glaciofluvial sediments.

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.
