Snowpack Summary
A light amount of new snow has added to heavily wind-affected surfaces from last week's strong northerly winds.
On south and west facing slopes up to 1400 m a surface crust from spring sunshine can be found, while other aspects hold dry snow. The mid-snowpack is generally strong, overlying weak basal facets at the base of the snowpack.Â
Terrain and Travel
- Pay attention to cornices and give them a wide berth when traveling on or below ridges.
Problems
Cornices
Cornices may be weak and reactive to human triggers. They are a significant hazard alone, and may produce large slab avalanches as they fall onto the slope below. Cornice falls are more likely as temperatures warm each day, or when strong sunshine is present.
Aspects: All aspects.
Elevations: Alpine.
