The Boulder Barricade at Cap a la Baleine, North Shore of Gaspe Peninsula (Quebec): Nature of Boulders, Origin and Significance
Bibliographic record
Abstract
A small (1.5 km long) boulder barricade occurs at Cap a la Baleine on the north shore of Gaspe Peninsula, about 25 km NE of Matane, The boulder barricade is a low ridge at the low tide level formed by a pavement of small to medium size subrounded to rounded clasts of various lithologies. Boulders are closely packed together and compacted into the underlying clay substrate. There are two main groups of boulders. About 40% are Precambrian erratics from the Laurentidian Shield on the north shore of the St. Lawrence estuary, whereas the remaining are from Appalachian lithologies occurring on the south shore of the St. Lawrence, of which 54% are sandstone (graywacke). A few particular indicators are anorthosite, dolostone, quartzite and volcanic erratics. Boulders remaining on the tidal flat surface are a lag from the erosion of a clay diamict, an event which occurred during the Upper Holocene. Originally deposited in the Goldthwait Sea circa 13-13.5 ka, the boulders are most likely iceberg drifted erratics from two sources: the Laurentides Ice Sheet still occupying the St. Lawrence valley, and the Appalachian ice, the front of which corresponding to the present shoreline at the time. Today, the Cap a la Baleine boulder barricade forms a natural wave breaker slowing erosion of the tidal flat.

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.
