Snowpack Summary
10 to 15 cm of low-density snow sits over a supportive crust. At upper elevations, deeper deposits of wind-loaded snow may exist, up to 30 cm deep. These small wind slabs are trending stubborn, but may still be reactive in isolated high-elevation areas.
The remainder of the snowpack has no layers of concern.Â
The alpine snowpack depth ranges from 70 to 180 cm at White Pass. Snowpack depths decrease with elevation and as you travel inland.
