Avalanche Summary

The avalanche danger is slowly trending down, but you can still trigger a large, dangerous slide on northerly and east-facing slopes near and above treeline. Winds drifted the most snow onto those slopes forming cohesive slabs of snow on top of weaker snow layers. Triggering an avalanche in a wind-loaded area can break wider than you expect, and take the entire season’s snowpack with it. Place an extra buffer between you and suspect slopes as you could trigger a slide from below a slope or from a distance. Avoid places that look filled-in or rounded, and retreat to slopes less than about 30 degrees if you see cracking in the snow, hear rumbling collapses, or see recent avalanches.
