These three avalanches appeared to happen on Thursday and to this point have gone unreported. See Photos 1 and 2: Elevator Shaft/Mt. Millicent, NE. This appeared to be triggered by a Snowboarder as he/she cut across the top part of the Chute. The slide was approximately 500 feet wide and ran at least 800 feet. See Photos 3 and 4: Martha's Bowl, NNW. This was a Natural and it went wall to wall, 750 feet wide and ran 350 feet. See Photo 5: Pioneer Main Chute. This appeared to human triggered and the only crown visible was the right flank, yet the debris was obviously indicating at least a D1.5. All of these slides appeared to match the activity and Avalanche Problem Type observed over the past 24 hours. And these all appear to likely have a Persistent Weak Layer issue directly above the previously formed pre-storm m/f crust.
