Avalanche Summary

No new avalanches were reported on Saturday.

NOTE: Observations are currently very limited in this region.

Snowpack Summary

Up to 10 cm of recent snow may be found at upper elevations. This snow overlies a robust crust everywhere except northerly aspects at upper elevations. Recent westerly wind may have formed small wind slabs on lee aspects at upper elevations.

Most terrain has undergone strong melt-freeze cycles, creating a strong, well bonded snowpack. The one exception could be northerly aspects at upper elevations, where deeply buried weak layers may still be present.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Carefully evaluate big and steep terrain features before committing to them.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.

Problems

Cornices

Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.
