Snowpack: I saw 5-12mm SH between 9,400′ and 11,400- today on open an gladed NW-E slopes, irrespective of previous snow surfaces. It had grown on old tracks, on old wind crusts on windward features, groomers and undisturbed pow surfaces with impunity. Certainly widespread on the shady side of the compass near and below TL.
