Origin and Late Pleistocene to early Holocene activity of the Albany Pine Bush dune field, New York, northeastern USA
Bibliographic record
Abstract
Well-preserved stabilized parabolic dunes occur in the Albany Pine Bush (APB), New York State, northeastern USA. This area was glaciated by the Laurentide Ice Sheet (LIS) and subsequently inundated by glacial Lake Albany until ∼ 13.0 ka. Glaciofluvial and glaciolacustrine deposits provided source sediments for dunes, which migrated towards the east-southeast. This integrated study addresses the morphology, grain mineralogy and micromorphology, stratigraphy, and chronology of a stabilized parabolic dune in the APB. The dune was active from 12.5–11.0 ka and was formed from locally-derived fluvial sediments that are slightly older (ca. 13.3–12.5 ka). The dune sands and underlying fluvial sediments are both texturally and mineralogically similar. Micromorphological analyses indicate that the dune quartz grains exhibit few characteristics typical of eolian transport, but inherently retain features of subaqueous origin. Consequently, both the distance and the duration of eolian transport during dune construction were very short. Dune stabilization coincided with the end of the Younger Dryas coeval with a forest transition from spruce ( Picea ) to pine-oak ( Pinus-Quercus ). The well-preserved morphology of dunes, and an absence of paleosols and stratigraphic truncations, all support dune stability throughout the Holocene, even with recurrent wildfire to which the local ecology has adapted.

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.
