Abstract
North America’s largest oilfield was discovered in 1968 at Prudhoe Bay; it contained over ten billion barrels of recoverable oil about 3000 m beneath the Arctic Coastal Plain. Its development changed Alaska’s economy for ever, and included building the oil pipeline from Prudhoe Bay to Valdez. The haul road alongside the pipeline is still the only road across northern Alaska, and was named the Dalton Highway when it was opened to public access. It crosses the wilderness of the Brooks Range (⇓Fig. 1), and allows completion of a north–south traverse of Alaska, across a broad range of geology and geomorphology; it was the destination for a Geologists’ Association field trip in 1999, when these notes were compiled. Fig. 1. A truck on the Dalton Highway across soliflucted slopes north of the Atigun Pass over the Brooks Range. The two great mountain ranges of Alaska, the Alaska Range in the south and the Brooks Range in the north (⇓Fig. 2), are accumulations of accreted terranes on the convergent plate margins of the Pacific and Arctic Oceans respectively, and both developed major icecaps during the Pleistocene; large glaciers are still fed by Pacific-derived rainfalls on the Alaska Range, but there is none today on the drier Brooks. The intervening Yukon valley and the Arctic Coastal Plain are cold deserts in the mountain rain shadows; they are classic periglacial environments (⇓Ferrians 1994). Their total lack of glaciation throughout the Pleistocene is perhaps most famed for the consequent survival of many rich placer gold deposits, notably in the Klondike valley, just over the border in Canada (⇓Waltham 1995). Fig. 2. Major geomorphological features across Alaska. Permanently frozen ground develops where all the groundwater freezes due to the cooling effect of the air. Continuous permafrost occurs where the mean annual air temperature is lower than about …

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
