“…To identify meaningful patterns between avalanche hazard and terrain choices numerically, it is critical to encode the nature of the available ski runs in a concise, but insightful way. Avalanche terrain research in the context of backcountry recreation has traditionally primarily focused on standard terrain characteristics such as slope incline, slope shape, elevation, aspect, and vegetation density (e.g., Hendrikx et al, 2016;Thumlert and Haegeli, 2018). More recently, Harvey et al (2018) developed a more sophisticated approach that combines an automated identification of potential avalanche release areas with avalanche simulations using RAMMS::EXTENDED (Bartelt et al, 2012;Bartelt et al, 2016) and fall simulations to develop thematic avalanche terrain maps that identify potential avalanche release areas, remote triggering of avalanches, possible runout zones, and the potential of being seriously injured or deeply buried by small or medium-sized avalanches.…”
