Avalanche Summary

No new observed or reported today

Snowpack Summary

Valley bottom is a typical spring snowpack with several crusts offering good travel. At about 2250m the crusts start to peter out and the snow pack feels much more wintery. On south aspects the crusts continue much higher, but on the more polar aspects the crusts eventually give way to a well settled snow pack with isolated windslabs in immediate lee areas.

Terrain and Travel

  • Recent wind has varied in direction so watch for wind slabs on all aspects.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
