| Mass movements are a widespread and frequently destructive occurrence in high-relief
landscapes including northwest Wyoming's Teton Range. Since critical human infrastructure
often co-occurs within these landscapes, landslide inventory maps serve as foundational datasets
for assessing hazards and risks posed by future events. Here we use a 2014 LiDAR elevation
dataset to produce a novel landslide inventory geodatabase encompassing ~1040 mass
movements throughout Grand Teton National Park. Our diverse inventory serves as the basis of a
geostatistical investigation exploring the extent to which various topographic domains and
substrate lithologies contribute to variations in landslide occurrence and type. We find that mass
movements occur in unique topographic and lithologic settings, and that slope and lithology
provide the strongest predictors of the spatial distribution of the different types. These statistical
findings provide a foundation for future susceptibility analyses and advance our understanding of
where and how mass movements occur in other landslide-prone regions.
