Physiography and Tertiary base levels in the southern Interior Plateau and adjacent areas, southwestern British Columbia
Bibliographic record
Abstract
Geomorphology, valley-fill geology, and drainage anomalies indicate that a suite of early Tertiary and older valleys occurs in the study area. Eocene relief and base level of the North Thompson River valley were the same as today,1000m and400mrespectively.The valley predates the middle Eocene. TheThompson River from Kamloops to Martel follows the trend of a broad Eocene valley and is inset 125 to 350 m below the sub-Eocene unconformity. The Thompson River valley from Martel to Lytton and the Nicola, Nahatlatch, and Stein river valleys define a branching, north-flowing drainage pattern that post dates the Eocene Fraser Fault. The Nicola Lake valley is probably Paleocene to Eocene. A former drainage divide existed along the Fraser River valley between Anderson River and Hell's Gate. Base level was about 500 m higher in the Miocene than in the Eocene.

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.
