Human-Centered Avalanche Susceptibility Mapping, Lindsey L. Rotche

Geography ETDs

With backcountry winter travel increasing in popularity, the importance of accessible avalanche safety information is crucial. Widely accessible avalanche backcountry maps use slope shading to show where avalanches are likely to start. Instead of focusing on the hazard of an avalanche starting in a specific location, this project shifted the cartographic emphasis of avalanche susceptibility maps to show risk to a human traveling in the terrain. I developed a methodology to incorporate possible avalanche runouts, terrain traps, and connected slopes while reducing false certainty of the visualization. To provide a more comprehensive representation of susceptible terrain, I integrated aspect, distance …
