A lithic analysis of the Jackson site (DiMe-17) in southwestern Manitoba
Bibliographic record
Abstract
The Jackson site (DiMe-17) is a Late Precontact site located in the Lauder Sand Hills of southwestern Manitoba. Primarily a bison kill and processing locale for Vickers focus people, this winter occupation has a calibrated radiocarbon date range between A.D. 1427 and A.D. 1683. Although a small Blackduck component was evident in the southwest corner of the site, the Vickers focus occupation was the dominant presence at this site and is the focus of this thesis. Archaeological investigations between 1994 and 1997 yielded a sample from 36 one square metres excavation units and 67 shovel tests pits. As part of an extensive investigation of Plains Woodland occupation of the region over the past 1200 years, excavation of the site served to provide additional information about Vickers focus occupation within the Makotchi-Ded Dontipi locale. This study offers a lithic analysis that encompasses the debitage and tools with an emphasis on the spatial distribution of the lithic materials. This seeks to assess the validity of the proposed activity areas at the Jackson site. The lithic analysis verified the presence of habitation and kill areas. Lithics from the east-central part of the site indicated processing activities as opposed to a large midden area associated with faunal processing as initially proposed in earlier studies. Late Side-notched projectile point types dominate the assemblage from the site. Plains and Prairie Side-notched point styles are affiliated with the Mortlach phase, Central Plains Tradition, Mississippian Tradition, and Middle Missouri Tradition. The Vickers focus people may have interacted and exchanged lithic materials with these groups. The Vickers focus people utilized exotic (Knife River flint, Tongue River silicified sediment, obsidian) as well as local materials (chalcedony, chert) to manufacture their tools.

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.
