Avalanche Summary

We haven't received any reports of avalanche activity on this region.

Please consider sharing your observations to the Mountain Information Network.

Snowpack Summary

Around 15 cm of soft and dry snow may be found in high elevation northerly alpine terrain, with deeper deposits possible in immediate lee features. Elsewhere, a hard melt-freeze crust exists, which will soften with daytime warming.

There are no deeper layers of concern at this time.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.

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.
