Avalanche Summary

New snow and easterly winds increase avalanche danger at upper elevations. You can trigger avalanches in wind-drifted snow on steep slopes, especially below ridgelines and in cross-loaded gullies.

Look for cracking in the drifted snow as a sign that the new snow is stiff enough to avalanche. Head to wind-sheltered terrain or slopes less than 35 degrees in steepness for safer travel.
