Snowpack Summary
A thin suncrust was evident in valley bottoms today and solar aspects to 2200m.
Continued snow transport today. All open areas at treeline and alpine have wind slabs. These look plump and likely triggerable in steep convex terrain. Cornices have also grown with the wind and warmer afternoon temperatures. With slab growth, the Feb 14th layer is now down 60-80cm, and maybe up to 100cm in wind loaded areas. Despite the wind, below tree line areas, or very sheltered treeline areas have nice settled powder snow offering good skiing/riding.
