Avalanche Summary

Fresh wind-drifted snow on weaker, faceted snow increases your chance of triggering an avalanche. Avalanches triggered near the surface could step down to weak snow layers at the ground. Avalanches breaking on weak snow near the ground will produce the largest slides. Avoid slopes steeper than about 30 degrees with about 10 inches of drifted snow, or places with a smooth, pillowy appearance and areas that feel hard and sound hollow.

If you see shooting cracks, hear 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.
