A brief how-to for common snowpack tests to locate and assess instabilities within the snowpack, presented by Mike Conlan. #ect #extendedcolumntest #rb #rutschblock #pst #propagationsawtest #compressiontest #ct #handsheartest #deeptaptest #dt #crackpropagation #avalancheforecasting Start times of tests in this video are as follows: 1:32 Compression Test 5:06 Deep Tap Test 7:28 Extended Column Test 10:54 Rutschblock Test 14:48 Propagation Saw Test 18:48 Shovel Shear Test 20:49 Hand Shear Test 22:11 Concluding remarks on initiation, propagation, and limitations. The specifications in this video are based on OGRS (Canadian Avalanche Association 2016). See https://vimeo.com/479569510 for the U.S. interpretation of the ECT, which was adopted in Canada in 2024.

Hopefully, this presentation will spark discussion on how to classify avalanche size, especially for big avalanches. Based on a paper presented at the 2014 Geohazards 6 conference in Kingston, Ontario.

An opinion on the much debated question about whether or not to do snowpack instability tests. Includes ECT technique and interpretation. Doug Chabot and Bruce Jamieson #snow #avalanche #snowpacktest #stabilitytest #avalancheforecasting #ect #extendedcolumntest #dougchabot #propagation

A video chat with Iain Stewart-Patterson, May 2021, about intuitive and analytical thinking, trip planning, decision aids and mindsets for recreation in avalanche terrain. #avalancheterrain #backcountryrecreation #heuristic #analytical #intuition #decision-making #iainStewart-Patterson

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 estimates from a distance. March 2022. #avalanchesize #calibration #destructivepotential #size #snow #avalanche

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. #avalanche #size #visualization

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.
