Abstract
Northeast Manitoba is mantled by glacial and post-glacial sediments, with scarce bedrock outcrops. Past ice-flow reconstructions in northern Manitoba suggest that the region has been covered at least twice by ice from the Keewatin sector, and at least three times by ice from the Labradorean sector (Dredge et al., 1986; Klassen, 1986; Dredge and Thorleifson, 1987; Boulton and Clark, 1990; Dredge et al., 1990; Dredge and Nixon, 1992; Kaszycki et al., 2008). This map builds on previous 1:250,000 surficial mapping completed in the 1980's (Dredge and Nixon, 1981, 1982). The northern part of the study area is characterized by extensive swaths of bouldery drumlinized and pristine (non-drumlinized) Rogen moraine ridges alternating with swaths of streamlined terrain. The remaining area is characterized by bedrock topography draped by a mix of till blankets and till veneers. Long, large eskers are present throughout the area, at roughly 18 km intervals. Where the eskers are located below approximately 200 m asl, they have been partially eroded by lacustrine and/or marine waters. Below 150 m asl, the eskers exist as washed, low-lying sand and gravel blankets rather than ridges. A mix of organic blankets and marine sediment is present in the eastern portion of the study area, predominantly below150 m asl. The study area has, in part, been wave-washed by either or both the postglacial Tyrrell Sea and Glacial Lake Agassiz or other smaller disconnected glacial lakes. The marine limit in the study area is around 180 m asl. Field data were obtained by helicopter-assisted ground-truthing in 2009 and 2010. Further description of map units, with photos, can be found in Trommelen and Ross (2009) and Trommelen et al. (2010). Field data are available in McCurdy, M.W, et al. (2011).

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.
