Avalanche Summary

You could trigger an avalanche on steep slopes at upper elevations where a cohesive slab of snow sits above older, weaker snow. You are more likely to impact this weak layer and trigger an avalanche near exposed rocks and on steep convex rolls where the snowpack is more shallow. Northerly and easterly-facing slopes are the most dangerous. Slopes less than about 35 degrees steep offer safer travel options.

As the snowpack continues to weaken, your chances of triggering small Loose Dry avalanches increase. Be prepared for facet sluffs if you travel in steep, constricted terrain at lower elevations.
