The landslide was initiated in a succession of sub-horizontal competent mafic basalts (Endako Formation) capping weaker felsic volcanic and volcaniclastic rocks (Ootsa Lake Group) of Eocene age. Several landslides have been observed in similar volcanic successions worldwide including in southern British Columbia. Some common characteristics of these landslides are: structurally undisturbed; horizontal to sub-horizontal bedding; curved head scarp; steep joints; debris consists of intact blocks; volcaniclastics containing smectite (expandable clay mineral); fossils and lignite within the volcaniclastics. The Sutherland landslide is one of many large landslides that have occurred in recent years in northern British Columbia. At least eight other large landslides have been triggered in volcanic rocks within the Nechako plateau.

How this classification was reachedexpand
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.
