Comments
This slide in Days Fork in the Banana Belt looks to have occurred 12/24 from new wind and snow load. It has similar characteristics to another slide in Main Days just to the south. Northeast-facing slope at 10,400'. You can see both slides in Pic 2.
[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.]
