Crested Butte Avalanche Zone Mapping

Overview

Spatial analysis identifying seasonal avalanche zones in the Crested Butte backcountry. Northeast-facing slopes accumulate wind-loaded snow through fall and become unstable first; southeast-facing slopes destabilize later during spring melt. Hazard layers overlaid on a hillshade base for route-planning context.
