After a dry first three weeks of January, and limited snowfall through Oct, Nov, and Dec, the underlying snowpack was very weak and faceted. Approximately 30" of snow and 2.5" SWE fell between Jan 22-30. A three day period of sustained 25-35 mph southerly winds occurred mid-week, in between storm systems. It was reported to me that this avalanche was snowmobile triggered. I don't know the actual date but it was between Jan 26-29.
