Snow obs Donner Peak

We toured up to Donner Peak and descended down N and NE facing aspects. Along the way we observed intact surface hoar ranging from 2 - 8mm in size. We didn't get observations on any significant solar aspects but the surface hoar. persisted throughout the day on NW - NE aspects. We observed some pockets of windslab on NE aspects that sat below 15cm of newer snow that were still reactive to isolation and ski cuts. Moderate blowing snow was seen in the later portion of the day as the next storm system comes in this evening.
