This year has been relatively dust free. I haven't been up in the Cottonwoods for a while, but reports suggest that the snowpack is relatively clean and that was the case in April when I last made turns. Yesterday, however, we saw some wind-blown dust over the Salt Lake Valley, with some obscuration of the visibility both in the pre- and post-frontal environment.
The lack of dust events is good for skiers. It makes for better spring skiing, but also a longer ski season since it results in a longer duration of snow cover in the mountains. Dirty snow is darker and absorbs more sun than clean snow, resulting in a faster snowmelt.
