Evidence of An Ice-Dammed Lake and Laurentide Readvance Upper Susquehanna Valley, New York State
Bibliographic record
Abstract
Landforms and well logs document a system of ice-contact and proglacial lakes in the upper Susquehanna valley during Laurentide Ice Sheet retreat from the Appalachian Plateau, central New York State. Recessional moraines formed dams for all lakes, except a newly revealed “Ancestral Goodyear Lake” retained behind an ephemeral ice dam stranded at Colliersville. A prominent dead-ice sink currently occupies the valley floor at the dam site Ancestral Goodyear Lake held a stable lake level at 1360 feet as represented by thick lake sediments perched in water well logs on the valley wall above Goodyear Lake. A deltaic terrace at 1250 feet in the same vicinity marks a second, lower lake strand. In addition, water well logs on the adjacent Portlandville Moraine contain lake sediments bound above and below by ice-contact material deposits thus demonstrating a Laurentide readvance that subsequently dammed the valley to form Glacial Lake Milford as part of the Susquehanna Lake System.

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.
