Abstract
Regional Quaternary mapping and stratigraphic and sedimentological studies were undertaken in the Glenlyon map area (NTS 105 L), with stratigraphic studies extending westward into the Carmacks map area (NTS 115-I). Surficial sediments were divided into 23 units, which range from Early Pleistocene to Holocene. Evidence exists for at least three glaciations: pre-Reid (Early Pleistocene), Reid (Middle Pleistocene), and McConnell (Late Wisconsinan). Deposits of the Pre-Reid glaciation(s) have a very subdued surface morphology. The Reid Glaciation was less extensive and has better preserved landforms. Organic beds of Middle Wisconsinan age were identified, and insect macrofossils and pollen indicate forested conditions at 36 000-37 000 BP. Landforms and sediments of the McConnell Glaciation are well preserved, allowing for better reconstruction of conditions than the previous glaciations. The stratigraphic record suggests that rivers aggraded and an oscillation in the location of the ice front occurred during glacial advance. At glacial maximum, the Selwyn and Cassiar lobes of the Cordilleran Ice Sheet affected the area, with topography strongly controlling ice flow. Because of aridity, local cirques in the Glenlyon Range supported only small glaciers that did not contribute to the Selwyn Lobe. At the end of the McConnell Glaciation, the retreat of glaciers was very rapid, with the ice sheet downwasting and stagnating in place. Many small lake basins developed in the Pelly River valley and large thicknesses of sediment were deposited on top of stagnant ice. Sediments were derived from the active ice margin, stagnant ice, marginal streams, and recently deglaciated valley sides.

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.
