Avalanche Summary

You could trigger a large and dangerous avalanche if you find a shallow spot and affect a buried weak-layer in the middle or bottom of the snowpack. Likely, trigger points are near the margins of the slab and include shallow buried rocks, convex rollovers, and just below ridgelines. Avalanches will be easier to trigger on shallow westerly and southerly slopes, but larger on northerly and easterly slopes. Avalanches in freshly drifted areas could step down deeper in the snowpack.

You can find safer travel options on wind-sheltered slopes at lower elevations and lower angle slopes without steep overhead hazard.
