At least on high north-facing slopes. There's 2' of snow where I skied today in the Sawtooths, and that's not going anywhere soon.
With fall arriving at 2 pm, the first part of our tour was in summer. I've never skied so much new snow in the summer. Felt more like winter at times.
Some pics to give you an idea of the coverage:
Needless to say, I wouldn't plan on going into the high country for the next week without skis or snowshoes.
