Avalanche Details

Skier 1 triggered a soft slab ~50 feet wide about 8-12" deep on the common SW slope of Sunburst about 2 turns in. Debris was very soft but was able to carry momentum and run to the valley floor through drainages. Skiers 2 and 3 were easily able to trigger additional pieces of slab adjacent to the first slide, but group skied on bed material there after.
