A structural investigation of the Hope Slide, British Columbia, using terrestrial photogrammetry and rock mass characterization
Bibliographic record
Abstract
On the 9th January 1965, from the southwestern slope of Johnson ridge, 150 km west of Vancouver, approximately 15 km from Hope along the BC Highway 3, a 44 million m3 rock slide fell in two separate events, between 4 am and 7 am (VON SACKEN, 1991); the movement assumed the behavior of a rock avalanche. The sliding mass fell down, filling the Outram Lake, destroying and burying several km of the BC highway 3, sweeping away and killing four people, which were unfortunately never found. As a result of the slide, the valley floor was raised of about 70 m with respect to the original topography. Hope Slide represents the major historical rock avalanche in Canada.\nThis work summarizes the results of a geological, structural and geomorphological survey of Hope Slide, obtained with long-range terrestrial digital photogrammetry (TDP) which allows, through the elaboration of pairs of images, the building of tridimensional models of the object.

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.
