Comments
Viewed multiple recent natural avalanches from the Miller Hill ridgeline looking across to the Y Not and Paradise Found runs (WBSkiing app). This is in middle Mary Ellen Gulch in Upper AF Canyon. The images below show a natural cornice fall and some nearby wind slab avalanches that look like they could have run on the most recent PWL judging by their depth and shape.
