The Science Behind Surface Hoar, Part 3

The Science Behind Surface Hoar, Part 3

In Part 3, snow scientists Bruce Jamieson and Simon Horton close out their surface hoar deep-dive by reviewing terrain selection and how professionals track persistent weak layers.


There’s a wonderful bit of wisdom included from guide Marc Piche, along with where and when surface hoar layers can be triggered and trip-planning considerations.

We hope you’ve enjoyed this series on surface hoar. If you’ve ended the series feeling like you want to learn more, we recommend signing up for a professional level avalanche coarse (in the USA here and in Canada here), and read The Avalanche Handbook by David McClung.
