Surface hoar and graupel at Stanford Rock

I observed graupel fall ~5pm 3/19 at my house in Alpine Meadows at 6450'.  This morning in Ward Canyon near the homes, graupel was on the streets and driveways.  I also observed it a lower elevations along the skin track.  In some places graupel was intermixed with surface hoar.

Significant surface hoar was along most of the skin track.  Photo is at 8000 ft on north aspect.  Yesterday, I saw surface hoar on Lakeview Chair, so it has formed the last two nights.
