Snowpack Summary

Warm temperatures to the mountain top combined with the strong spring sun has made most snow surfaces moist, except on the true North facing alpine slopes. With some overnight cooling, a melt-freeze crust may form on most aspects and elevations. Isolated pockets of wind slab may linger in the alpine just below ridgelines. 

Along ridgelines, cornices are large and looming. They are very unpredictable and require a large berth if you're travelling above and below. 

Terrain and Travel

  • Avoid slopes when the solar radiation is strong, especially if they have large cornices overhead.

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.
