An inside look at how people trigger slab avalanches

This video outlines - for a wide audience - the current understanding of how rider-triggered and natural avalanches start. Bruce Jamieson, Karl Birkeland and Ron Simenhois, January 2023. CC BY-ND.

Is slab tension a condition that makes rider-triggered avalanches more likely?

Is slab tension a condition that makes rider-triggered avalanches more likely?

Slab tension means different things to different avalanche practitioners (survey summer 2022). In this (controversial?) 21 minute video, Bruce Jamieson, Karl Birkeland, Grant Statham and Scott Thumlert summarize some common perceptions about slab tension, then review the role of slab tension in the modern understanding of dry slab avalanche release.
Estimating avalanche size - from far and near

Estimating avalanche size - from far and near

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

Triggering a persistent slab avalanche from a thin spot

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 intro to snow avalanche dynamics and impact

An intro to snow avalanche dynamics and impact

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.

Iain Stewart-Patterson on intuition and making decisions for recreation in avalanche terrain

From 3 to 30. How many levels should a rating have?

From 3 to 30. How many levels should a rating have?

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

It's convex. Should I avoid it?

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.
