YUKON EXPLORATION AND GEOLOGY 2004 247 Case study of Donjek debris flow, southwest Yukon
Bibliographic record
Abstract
A high-magnitude debris flow occurred in late summer 2000 from tightly folded sedimentary rocks in a steep 2.66 km2 basin in the remote Donjek River valley of southwest Yukon. The debris flow deposited at least 206 344 m3 of material, with a peak discharge on the order of 1000 m3/s. No evidence of any previous events of this magnitude was found at the site. The headscarp is aligned with the strike of a west-plunging overturned syncline in heavily weathered Upper Paleozoic to Upper Triassic argillite, interbedded siltstone and argillite, and thinly bedded limestone. Tree-ring analysis on two white spruce killed by the debris flow indicate that the debris flow occurred in July to early-mid August 2000. The heaviest monthly total precipitation on record (1967-2003) for August occurred in 2000 and most likely played a role in slope failure. The volume and peak discharge estimated are the largest reported from a debris flow occurring in the last 100 years in the St. Elias Mountains. RÉSUMÉ
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
