Comments
Noticed this avalanche in Main Days on a northeast aspect at 10,400'. No ski tracks visible. In the upper right of pic 2 you can see another sizable slide in the Banana Belt. Looks like similar timing.
[Forecaster Comment - Thank you for the observation. The avalanche was initially triggered by the helicopter landing at the top of Banana Belt, and that slide sympathetically released the two other avalanches in Main Days.]
