This avalanche was triggered by a snowboarder who was able to get off the slab safely. It was a recently formed wind slab about 8-10 inches deep, but the notable thing is how wide it broke. It failed on a thin layer of small facets formed during recent cold clear nights and warm sunny days. Photo: GNFAC

It was a recently formed wind slab about 8-10 inches deep, but the notable thing is how wide it broke which indicates it may have been sitting on a layer of small facets. It occurred on a S aspect near 9700 feet in elevation. Photo: J Losier
