Abstract
Electrical resistivity measurements in northern Wisconsin show the presence of a large high-conductivity anomaly in the crust. The anomaly, which we refer to as the Flambeau Anomaly, is approximately 20 km wide, lies roughly along 46°N latitude, and extends east of 91°W longitude for more than 100 km. Detailed airborne electromagnetic surveys over parts of the anomaly show that the anomalous region consists of four to six roughly parallel conductive formations. Core samples from these formations indicate that graphite, sulfides, and iron formation are the principle conductive materials causing the anomaly. Numerical analysis of resistivity soundings surrounding the Flambeau Anomaly indicates the following layered earth crustal structure: (1) a surficial cover of 0 to 100 m thickness has a resistivity of a few hundred ohm meters; (2) a second layer has a resistivity of a few thousand ohm meters and a thickness of 5 to 10 km; (3) a third layer has a resistivity of greater than 105 ohm m; (4) at depths of 15 to 25 km the resistivity decreases to the order of 1000 ohm m. Our model of the Flambeau Anomaly consists of five thin vertical half plane conductors. Numerical modeling indicates that the conductors extend to a depth of the order of 10 km. The Flambeau Anomaly appears to be a major structural feature in the southern extension of the Canadian Shield.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
