Review of <i>Epic Wanderer: David Thompson and the Mapping\nof the Canadian West</i> By D'Arcy Jenish
Bibliographic record
Abstract
David Thompson, often known as "the great mapmaker," spent twenty-five years traveling the entire West and Northwest of North America, covering 75,000 miles by canoe, horseback, and foot, and in the process produced the first comprehensive map of this vast region of about 1.2 million square miles. He then spent many years surveying the new 49th parallel boundary between the United States and Canada.\nD'Arcy Jenish has produced, according to his publisher, the first full-length biography of Thompson-in that previous works have not given much consideration to his early and declining years-and has done a creditable job of following and explaining Thompson's travels in the West. The book describes in some detail how Thompson worked to achieve the precision characteristic of his surveying, the key to which was his innumerable astronomical observations taken with infinite care under often extremely adverse conditions. These allowed Thompson to fix the exact position of thousands of points across the West, which, coupled with his careful running surveys between these points, yielded maps of unprecedented accuracy.\nThe book does not seem to cover much new ground or reveal any new research. There are no new answers to the question of precisely what drove him in 1797 to leave the Hudson's Bay Company and take up with the North West Company, and no new reasons why Thompson suddenly gave up his life in the wilderness in 1812 and started living in the first house of his own as a sedentary farmer and land investor-the latter being what ultimately got him into so much trouble and left him a pauper. And there is nothing new that might explain better why Thompson took so long to reach the mouth of the Columbia in 1810, when his company's-and even his country's-fortunes depended on it. He arrived at the Pacific to find Fort Astoria already built and occupied by the men of Jacob Astor's rival Pacific Fur Company. Has all we are going to uncover about David Thompson already been found?

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.
