The compilation of 343 989 seismic shothole drillers' logs from continental Northwest Territories and northern Yukon, in database and GIS formats, provides a large new source of lithostratigraphic data. Use of this previously disregarded data has enabled reconstructions and models of potential granular aggregate resources, massive and ground ice occurrences, geohazards, muskeg and drift thicknesses, and till facies. This information can be readily utilized to improve the efficiency and focus of environmental assessments, address issues of weathered zone static inferences for seismic exploration, better identify potential geohazards, and support the sustainable design and development of regional infrastructure.

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.
