We've had two dust events this week and dust is finally evident in the snowpack. The dust events occurred on Wednesday with the frontal passage and yesterday and today with the southerly flow. It appeared to me that the more substantive dust loading of the snowpack occurred on Wednesday at Alta as the dust was most evident where the new snow from Wednesday night had been skied off. Hand pits confirmed that the dust was concentrated near the bottom of the new snow layer.

Despite the strong winds, emissions from major sources in southern Utah appear to have been fairly limited yesterday and today. Thus, the dust concentrations were fairly low. I suspect the land surface is just not ready to go yet this year. Perhaps in a couple of weeks, although I'd prefer to keep the spring as dust free as possible.
