Avalanche Summary
Recent snowfall and strong winds built thick, dangerous slabs of snow on most slopes. Avalanches can break in the storm snow or they can step down into deeper weak snow layers on west through north, to southeast-facing slopes. You might trigger an avalanche from a long distance away or below a slope if you find a spot where the snowpack is thin near exposed rocks or margins of the slab. Avalanches triggered from a deeper, wind-drifted area could grow much wider and run much farther than you anticipate – resulting in a deadly avalanche. If you see shooting cracks or hear audible collapses, move to slopes around 30 degrees without steeper terrain overhead for safer travel options.
