Abstract
The Carmacks map area has been partly or extensively glaciated a minimum of four times during the past ca. 1.5 million years. The two oldest, named pre-Reid glaciations occurred prior to the last magnetic reversal (>0.78 Ma BP). The pre-Reid glaciations and subsequent Reid Glaciation were separated by at least two periods of interglacial climate. Interglacial climates were similar to those of today or radically warmer. The Wounded Moose paleosol developed early in this period. Auriferous placers were deposited in the Dawson Range. The glacial ice was less extensive during Reid Glaciation than during the pre-Reid glaciations. During the period between the Reid and McConnell glaciations, the climate warmed to one comparable to the present. The Diversion Creek paleosol developed during this mild interval. The glacial ice cover of the latest (McConnell) glaciation was less extensive than that of the Reid Glaciation. Following the end of the McConnell Glaciation, the Yukon River, and presumably other major streams, incised close to their contemporary levels by the early Holocene. Volcano Mountain erupted around the Pleistocene-Holocene boundary and may have been active during the mid-Holocene. Bedrock is characteristically competent in the study area with the exception of the Carmacks Group. The most significant occurrences of placer gold occur in the Dawson Range. They result from the weathering and transport of lode gold associated with intrusions of the felsic subvolcanic Mount Nansen Group. All existing placer operations either overlie or are topographically downslope from Mount Nansen Group intrusions.

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.
