Minimally Invasive High-Resolution Investigation of Site Form and Disturbance at Rat Island (AhGx-7), Cootes Paradise, Ontario
Bibliographic record
Abstract
This paper presents a reinvestigation of archaeological material at Rat Island (AhGx-7), a proposed Princess Point period site in Cootes Paradise, Ontario, Canada. Applying a minimally invasive coring and augering strategy paired with soil properties and high-resolution multi-element chemical evaluation, we established that a low rise on the landscape, previously attributed to Princess Point or Woodland period occupation, is instead associated with the a.d. 1830s construction of the Desjardins Canal. Comparing the distribution of anthropogenically associated chemicals across Rat Island, our results suggest that the portion of the Island impacted by canal construction likely contained the most intense evidence for human occupation. Furthermore, the distributions of chemicals across undisturbed portions of Rat Island fail to support previously postulated settlement patterning models, suggesting instead a location of variable and potentially ephemeral occupation. This study establishes the utility of core and auger sampling and Itrax™ multi-element analysis when seeking to understand site formation, presenting an alternative to more time-consuming excavation strategies.

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.
