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

Compression test technique along with site selection, finding persistent weak layers and recording results. The fractures are classified according to this video https://vimeo.com/30996756

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, December 2020. CC BY-ND

Starting with the likelihood definition and terms in the Conceptual Model of Avalanche Hazard (Statham et al., 2018), Scott Thumlert, Grant Statham and Bruce Jamieson present some ideas for improving avalanche likelihood and how it can be communicated.

An introduction to the tradeoffs that avalanche practitioners make in daily operations. Intended for a wide audience, which proved challenging! Bruce Jamieson, John Stimberis and Larry Stanier, September 2020. CC BY-ND.

A technical video for avalanche practitioners and recreationists interested in avalanche science. The video outlines the formation of faceted layers near melt-freeze crusts, the persistence of these layers as potential failure layers for slab avalanches and some ideas on anticipating the resulting slab avalanches. Bruce Jamieson and Scott Savage, May 2020.

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. May 2020. Catalan and Spanish subtitles by Montse Bacardit. German subtitles by Thomas Exner. CC BY-ND.

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

We explain why we prefer to describe conventional avalanche forecasting as an iterative process or, simply, updating. Bruce Jamieson and Karl Birkeland, July 2020. CC BY-ND.

When salt is added to snow, the snow cools because heat from the snow flows into concentrated salt water around the salt grains. The surprisingly large amount of heat required for melting (i.e. latent heat) contributes to avalanche formation in at least two ways.
