The consort pebble chert quarry site (EkOr-8) and the role of chert pebbles in pre-contact sites on the Canadian plains
Bibliographic record
Abstract
The Consort Pebble Chert Quarry site (EkOr-8) is a Pre-Contact quarry site located south of the Village of Consort, Alberta. Despite knowledge of the site's existence by local area farmers, it was only in 1999 that it was first recorded as an archaeological site. It is described as a large area dominated by the presence of marked depressions that vary in size from less than a metre in depth and diameter to well over three metres in depth and diameter as well as an abundance of chert pebbles on the ground surface. Originally believed to be an example of meteorite impacts, the site was explored by geologists from the University of Calgary. Further visits by provincial archaeologists resulted in numerous theories as to the cause of the depression features and the purpose of the site. No archaeological investigation was undertaken prior to the summer of 2006.No diagnostic artifacts were recovered from within the site area; however, a possible temporal indicator to site usage may be indicated based on the discovery of a Duncan projectile point in a site immediately to the south of the Consort Pebble Chert Quarry. An abundance of lithic artifacts were uncovered as results of the shovel test program undertaken by the author during the summer of 2006. The majority of these lithic artifacts were derived from the abundant lithic material within the site area known as pebble chert. No other non-lithic artifacts were found during the course of this excavation. Shovel tests were used to provide an indication of the subsurface stratigraphy at the site. No evidence of cultural strata was found and the subsurface deposits present reflect a history of glacial landscapes. A number of glacial phenomena are the likely causes of the depression features. The presence of pebble chert on the ground surface; however, did make this area an attractive location for collecting unmodified lithic material in order to fashion stone tools. The existence of numerous artifacts made from pebble chert at the site indicates that past cultural groups had visited and collected from the area. An overview of archaeological sites on the Canadian Plains demonstrates that pebble chert is a valuable lithic material that was used in a wide variety of archaeological sites throughout the Pre-Contact era.

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.
