Snowpack Summary
20-30cm of snow over the long weekend will create fresh wind slabs. These new wind slabs will sit over a thin and variable snowpack. Nov 10- Treeline snow depths 5-20cm.
Avoid wind loaded pockets in leeward areas and near ridgetop.
Many open crevasses are hidden by thin bridges of wind-blown snow. Roping up, diligent probing, and experience are critical for glacier travel.
