It's easy to underestimate the size of an avalanche from a distance. In this video, Bruce Jamieson outlines a method using on-site estimates of size to calibrate the estimates from a distance. March 2022. CC BY-ND

Triggering a persistent slab avalanche from a thin spot is infrequent, insidious and potentially deadly. This 6 minute video outlines the snowpack conditions and mechanics. Intended for intermediate and advanced backcountry recreationists and those interested in avalanche science. Feb 2022. CC BY-ND

An introduction to snow avalanche dynamics and impact. Includes avalanches in motion but no models and almost no math. Intended for anyone interested in avalanche science, early career avalanche practitioners, and Christian Jaedicke's students (perhaps as pre-course material?) Bruce Jamieson and Christian Jaedicke. October 2021.

Interviews with Marc Piché, Penny Goddard, John Buffery, Sylvia Forest and Larry Stanier. 18 October 2021

Having found little published guidance on the optimal number of levels in a rating system, Bruce Jamieson and colleagues use examples, mostly from avalanche and weather forecasting, to identify a basic guideline and several other considerations. 03:40 Matthew MacDonald on AQHI ratings 09:52 Matthew MacDonald on precipitation likelihood ratings 12:11 Pascal Haegeli on the avalanche danger rating 18:53 Jesse Percival on rating skier compaction 21:25 James Floyer on avalanche size ratings in public bulletins

Views on the roles of convexities in human triggered avalanches vary widely. In this educational video intended for intermediate and advanced winter backcountry recreationists, Ron Simenhois and Bruce Jamieson present various perspectives and research on human triggering near convex slopes.
