This video outlines some general advantages and disadvantages of avalanche decision aids. The advantages and disadvantages are general enough that – I hope – both backcountry recreationists and avalanche practitioners find something useful in this video. This video does not explain how to use any decision aids but does show four decision aids and identify where to find more information on them. #decision #decisionaid #avalanche #uncertainly #avaluator

Photos of 15+ avalanches so you can practice rating their size with the more visual method and compare your rating to ours. Bruce Jamieson, Montse Bacardit, Ethan Greene and Ian Tomm. May 2020

Climate change has been a focus for the avalanche world in recent decades. This presentation summarizes two papers that look at the snowpack and avalanches and how they have changed over the last 30 - 50 years in western Canada. For a 2022 paper by J. Hendrikx and others, search for: The potential impacts of climate change on snow avalanche hazards on the Trans- Canada Highway in Glacier National Park. #snow #avalanche #climatechange #trend #westerncanada #glaciernationalpark #rogerspass

This presentation is based on a paper by Bruce Jamieson and Alan Jones for the 2012 ISSW in Alaska. It reviews risk concepts then summarizes quantitative vulnerability for buildings, people in buildings, people in vehicles and people in the backcountry.

A video to start discussion about whether visualization will help us rate avalanche size on the D-scale. By Bruce Jamieson, Montse Bacardit, Ethan Greene and Ian Tomm.

Technique for the Extended Column Test (ECT) (with comments on site selection and interpretation).

Compression test technique along with site selection and finding weak layers. The fractures are classified according to the video https://vimeo.com/30996756 CC BY-ND #fracturecharacter #compression #test #snowpack #avalanche #nutshell

A cheesy animation of skier triggering. When the bulb of high stress under the skier reaches the weak layer, a crack starts. In this case the crack is long enough to propagate away from the skier, including up the slope. At some point up-slope of the skier, the tensile stress in the slab causes the crown fracture. The slab breaks from the snowpack and slides downslope and, in this example, carrying the skier downslope. Can be downloaded for use in avalanche education. 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. 22 Feb 2022.

Different people often assign a different size to the same avalanche. Considering deposit volume has been proposed to improve the consistency of size ratings. With the 2024 adoption of deposit volume into the scale of destructive potential for avalanches, visualizing deposit volume by how high the deposit would fill a house or hockey rink should improve the consistency of ratings. Thanks to Brendan Martland, Lisa Larson and Tyler Carson for helpful comments.

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.

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
