Avalanche Summary
No recent avalanches have been reported in the region.
Snowpack Summary
5 to 15 cm of recent snow overlies a widespread crust at treeline and below. At the highest elevations, the snow buried old wind affected surfaces.
The mid and lower snowpack are generally well consolidated, and likely still moist from the recent rain. Conditions remain rugged at lower elevations, with a shallow snowpack.
