A record of post-glacial moraine deposition and tephra stratigraphy from Otokomi Lake, Rose Basin, Glacier National Park, Montana
Bibliographic record
Abstract
The sedimentary record of Otokomi Lake, Glacier National Park, Montana, was studied to determine the age of an adjacent Crowfoot moraine. The presence of Mt. St. Helens Jy ash near the bottom of the longest percussion core limits drainage basin deglaciation to before 11 400 14C years before present (BP), although 14 100 BP is the estimated basal age of the core. Correlative shifts in loss on ignition, coarse (>1 mm) grain size, magnetic susceptibility, and X-ray gray-scale data at a depth of 185 cm are interpreted to be related to a sedimentary change in Otokomi Lake brought about by the deposition of the adjacent Crowfoot moraine. The estimated age of the moraine is 10 590 BP, which is within the Younger Dryas interval. This information supports the hypothesis that Crowfoot moraines represent a regional western North American response to Younger Dryas cooling.
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.
