Avalanche Summary
On Saturday small (size 1) storm slabs were reactive to skier traffic, primarily in lee terrain below ridgetops.
Snowpack Summary
Currently, the snowpack structure changes dramatically with elevation and aspect. Light amounts of new snow and extreme southeasterly winds on Saturday scoured windward surfaces and may have created fresh wind slabs much further down slopes than expected. These winds also created cornice growth. Expect these new cornices to be fragile.Below roughly 1900 m, the snowpack is moist and is melting rapidly at lower elevations.
