Notes
A skier triggered a low angled slope (29-30 deg). It was new snow that failed on a layer of graupel. Crown was 6” to 2’ at its deepest. Broke 400’ wide, maybe 200’ vert. The skier triggered the slide on descent and was not aware of the avalanche until he stopped at the bottom of the run. Skier had a partner, rescue gear and was not caught.
