Abstract
Abstract The distribution and pattern of subglacial bedforms provides valuable insights into the configuration and behaviour of former ice sheets and recent work has begun to address the landform assemblages of palaeo‐ice streams. In this paper, we focus on subglacially formed ice stream shear margin moraines; these landforms are thought to form in the shear zone between fast‐flowing stream‐ice and slow‐moving sheet‐ice. Using satellite imagery and aerial photographs, we identify four ice stream shear margin moraines associated with the former M'Clintock Channel Palaeo‐Ice Stream, Victoria Island, Arctic Canada. The moraines range in length from 11 to 22 km, maintain fairly constant widths of around 500 m, and range in height from 10 to 50 m above the surrounding terrain. They are composed of carbonate drift of a similar composition as the ice stream bedforms and have been laid down irrespective of local and regional topography. Two of the moraines display a lateral offset and are thought to reflect minor migrations of the ice stream margin. We explore their possible mode of formation and suggest that they occur when erosion at the ice stream margin provides a surplus of sediment which is ‘smeared out’ in the downstream direction. The identification of other palaeo‐ice stream shear margin moraines has probably been hampered by their interrupted continuity which can only be appreciated at the large scale. It is hoped that the descriptions presented in this paper will help to identify these landforms and increased detection of palaeo‐ice streams will reveal other ice stream shear margin moraines.

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 it
