While powsurfing in bench-like terrain, avalanches were easily triggered on top of convex rolls with the slightest human input. I suspect they were sliding on surface hoar and/or buried facets. It was spotty as the snow was stable in some places, and very sensitive in other spots. I saw 5 natural avalanches that probably ran during the storm ranging from 30-80ft wide, all on northeast facing slopes between 8000-9500ft. The terrain we were riding was pretty low angle with steep spots in between, and it was predictable where the slabs would be touchy. In bigger terrain with more vertical this depth of slide could do serious damage.
