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.Â
Along ridgelines, cornices are large and looming. They are very unpredictable and require a large berth if you're travelling above and below.Â
Terrain and Travel
- Avoid slopes when the solar radiation is strong, especially if they have large cornices overhead.
Problems
Cornices
Cornices are large and looming along many ridgelines, and have likely grown with the recent snow and wind. They become increasingly weak when the sun comes out and freezing levels rise. They require a large berth when travelling above and below them.
Aspects: North, North East, East, West, North West.
Elevations: Alpine.
