A presentation from the 2021 Colorado Snow Avalanche Workshop. This video on the risk management practices is a companion to the video How Risky is Ski Cutting by Avalanche Practitioners. Bruce Jamieson collaborated with Karl Birkeland, Mark Vesely, John Stimberis and Mike Sadan. #skicut #skicutting #avalanche #risk #mitigation #riskmanagement #snow #survey #practice #practitioner #avalancheoperation

Highlights from a survey of practitioners on the risk of ski cutting. The video is based on a paper by Bruce Jamieson, Karl Birkeland, Mark Vesely, Ilya Storm and John Stimberis. Risk management practices for ski cutting by practitioners are outlined in companion video: A Toolkit of Common Practices for Operational Ski Cutting. #skicut #skicutting #avalanche #practitioner #risk #riskmanagement #snow #mitigation

During re-construction of a powerline tower in northwest BC in February 1994, six people were stranded in a lunch shack for four nights. The shack was buried by an avalanche on the third night. In this video, two of the stranded, avalanche technician Hector MacKenzie and linesman Trevor James, recount being stranded and its impact on them. Another of the avalanche technicians Scott Flavelle provides some background on the powerline and the terrain it runs through. Recorded in January 2025 then edited.

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.
