Quick Observation
Toured in Red Sky/Unawah to sniff out some early season turns.
Snowpack around 6000' generally in the 2-3ft range; above 6500', varying from wind scoured to 4ft+
Surface hoar developement occuring in shaded, sheltered basins-5mm
Sustained SW winds from 20-30mph in the higher terrain. Active windloading on leeward (E) aspects. Spindrift/windloading evident on most peaks in the area as well.
We skiied a W aspect and found crossloading in gullies and draws. Small soft slabs (1-2") were very reactive in ski cuts and continued to run and entrain low density surface snow, creating loose, dry avalanches that could easily knock a rider down.
Overall; recent cold weather wreaking havoc on the thin snowpack which was generally stable, albeit weak.
