Comments
This storm slab avalanche appeared to have happened this morning during high PI rates triggered by a natural cornice drop. The crown was around 10 inches deep and about 300ft wide taking the whole skiers right side of the bowl out. The debris didn’t quite make it to the flats before it petered out. Big enough to take you for a ride but not big enough for a full burial in my opinion. The weak layer was the light density snow from last weekend which survived the heat due to its more northerly aspect than the right side of the bowl. There was also a smaller slide on the far skiers right corner  which goes into a narrow notch though the trees, same depth and maybe 30ft wide
