Abstract
Iowan Marietta (" Etta" ) Schaal poses in her wolverine parka, surrounded by three dogs and mining equipment, near Magnet Gulch in the Yukon.I n 1911, David F. Schaal donated an eight-foot mammoth tusk to the State Historical Museum.He had found it a decade earlier in the deep, gold-bearing gravel deposits of Magnet Gulch, near Dawson City in the Yukon.The museum displayed the tusk in the typical fashion of the day-in a "cabinet of cu riosities," showing the artifact for its own sake, but with no in terpretation to reveal its larger significance or context, and no story to capture our imagination.Nearly a century later, the museum again displayed Schaal7s tusk, in its "Mammoth: Witness to Change" exhibit.A museum visitor named Mabel Hudson, of West Des Moines, spotted the tusk and realized that it was the one donated by her father.She invited me to lunch and showed me her mother's photo albums and the following text, "Account of Trip to Yukon Territory."Here was the story behind the tusk.In 1900 Fred Schaal of Seattle had convinced his brother David, then of Polk City, Iowa, to travel with him to the Yukon.The next year David's wife, Marietta ("Etta") Schaal, and Fred's wife, Franc, joined their husbands in the goldfields.Thanks to Etta's words and photos (which she took with a small box camera), we see their Yukon adventure through the eyes of a 26-year-old Iowa woman. -Bill Johnson, museum curatorDavid F. Schaal holds the tusk-the left incisor-of a wooly mammoth, next to more tusks and bones found in the Schaal diggings.Mammoth remains, which in the Yukon date back 30,000 years, are also found in river and glacial deposits in Iowa.See the Schaal tusk in the " Mammoth: Witness to Change" exhibit in the State Historical Building, Des Moines.

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.
