Avalanche Summary

Strong northerly winds wreaked havoc on upper elevation slopes forming hard slabs of snow on top of weak, collapsible snow layers. Avoid slopes steeper than about 35 degrees with a smooth, pillowy appearance or where the snow sounds hollow like a drum. An avalanche triggered from a wind-drifted area or cross-loaded terrain feature could step down into deeper weak layers producing a larger, more dangerous avalanche.

If you see shooting cracks, hear loud collapses, or transition from soft to harder snow, choose an alternative route or different slope. Below treeline areas without steep overhead hazards offer safer travel options.
