Abstract
The surficial geology of the Nechako River map area (NTS 93F) depicts the distribution of unconsolidated glacial and nonglacial sediments and landforms. This A-series map was compiled, modified and generalized from previously published open files produced by the Geological Survey of Canada and the British Columbia Geological Survey. The map shows a variety of units of glacial and non-glacial origin. From oldest to youngest, the units on the map include bedrock and till and, glaciofluvial, glaciolacustrine, colluvial, alluvial, organic, and anthropogenic deposits. Till is the most areally extensive surficial deposit in the map area. It consists of a poorly sorted sediment directly deposited by glaciers, containing boulder- to pebble-sized clasts in a matrix of sand, silt, and clay. Glaciofluvial deposits generally consist of sand and gravel which can represent aggregate resources, but their quality for such usage depends on the sediment sorting and the induration of the clast lithologies. Glaciolacustrine deposits are composed of well sorted fine sand, silt, and clay. These sediments were deposited in former glacial lakes that developed at the end of the last glaciation when the drainage was blocked by decaying ice masses. Colluvial deposits represent sediments reworked by mass-wasting processes in steep terrain. Alluvial deposits (sediments of modern streams) are present along all streams in the region but only in the larger ones are such deposits extensive enough to be mapped. Organic deposits accumulate in poorly drained depressions in sediments and bedrock. They are particularly abundant in regions underlain by impermeable till, in valleys with underfit streams, and within low-gradient meltwater channels. Anthropogenic deposits, consisting of sediments reworked by human activities, were only mapped at the Kenney Dam site. A variety of glacial and non-glacial landforms are represented on the map. They provide and indication of the glacial and non-glacial history of the region. More details on the surficial geology and ice-flow history of the region is provided as marginal notes on the map.

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.
