Snowpack
North facing at the base of the Spider Face on the Sultan. 11600' Hard bed surface dirt layer with fresh snow on top. The fracture was probably a soft slab just below rocks
Avalanche
The narrowest part of the lower couloir had slid to the dirt layer. Just when it ended and the apron began I slowed down and pulled to the side to catch my breath. I saw the crack and turned right back on tho the bed surface. A pocket pulled out as a 2-3 foot crown about 100' across. It ran maybe 400 feet down the apron and came to a stop. I observed it while standing on hard dirty snow off to the side of but just below the crown.
