When travelling in avalanche terrain, avalanche risk is managed by choosing terrain the limits exposure to the existing hazard to an acceptable level while pursuing your activity. While mountain guides have a tremendous amount of practical expertise managing avalanche hazard, there has been very limited academic research on this important topic so far.

Our objective in this research area is to capture and quantitatively describe the risk management expertise of mountain guides to develop tools that make this expertise more easily accessible to avalanche professionals and backcountry recreationists.

  • Ski run classification for mechanized skiing

    What do the daily 'run list' ratings reveal about the operational character of ski runs?

    Objective

    The objective of this study was to explore whether large-scale professional terrain choices as systematically documented in the daily run list ratings by commercial backcountry skiing operations can be used to derive a holistic avalanche terrain classification. To identify similarly managed types of terrain we applied a pattern recognition approach in actual large-scale terrain management decisions of avalanche professionals over the course of multiple winter seasons. Terrain types were subsequently characterized with both topographic and operational attributes to provide a better foundation for the analysis of professional terrain management.

  • Capturing the essence of heli-skiing terrain

    How can we describe the nature of heli-skiing terrain? What are guides’ perception of the hazard, benefits and access barriers of their ski runs and how consistent are these perceptions?

    Objective

    Modern guiding teams at heli-ski operations possess extensive knowledge of the terrain existing in their tenure regions. The deep-rooted experience of these guides is obtained through years of practice, and guides develop a sensitive “feel” for how terrain can be used in response to daily avalanche conditions and to fulfill operational needs. The objective of this project is to develop and examine a framework for describing the nature of skiing terrain in a meaningful way that not only focuses on hazard, but also includes information on operational benefits and barriers to access. The information collected in this study will offer novel insight into how guides perceive their skiing terrain and how consistent these perceptions are. The results will provide important information for team calibration, mentorship of new guides and offer critical context for linking terrain choices to hazard conditions in a meaningful way.
