Avalanche Summary
No recent avalanches have been reported, but observations are limited this time of year. If you do head into the backcountry please submit a MIN report!
Snowpack Summary
The upper snowpack has been heavily wind affected, with hard wind slabs found on all aspects. Sustained cold temperatures have likely softened the snow surface in wind-sheltered terrain. Roughly 70 to 90 cm can be found at treeline in White Pass. Upwards of 100 cm may exist in wind-loaded areas. The lower snowpack consists of soft, sugary facets and a crust near ground level.
