Continental/Cordilleran ice interactions: a dominant cause of westward super‐elevation of the last glacial maximum continental ice limit in southwestern Alberta, Canada
Bibliographic record
Abstract
In southwestern Alberta, Canada, a westward‐rising last‐glacial‐maximum continental ice limit has been identified. This limit is defined by the upper elevation of Canadian Shield erratics deposited by last‐glacial‐maximum continental ice along the flanks of prominent ridges and buttes within the region. The interpolation between ice‐limit data points has produced two distinct slope profiles: 2.9 m/km to the east, and 4.2 m/km to the west of Mokowan Butte. Three hypotheses are proposed to explain this westward rise of the last‐glacial‐maxi ‐mum continental ice limit: (1) regional tectonic uplift, (2) glacioisostatic uplift, and (3) continental ice‐flow convergence due to topographic obstacles and interaction with montane ice. Inferred long‐term rates of tectonic uplift and glacioisostati c modelling show that these two mechanisms account for less than 25% of the observed absolute elevation increase of the limit between the Del Bonita uplands and Cloudy Ridge in southwestern Alberta. The remaining rise in elevation of the continental ice‐sheet margin in this region is thought to result from continental ice‐flow convergence due to the combined effects of the regional topography and interaction with montane glaciers to the west. The steeper rise in the former continental ice surface west of Mokowan Butte can be explained by the tographic obstruction and interaction with montane glaciers in the area of the Rocky Mountain front.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
