Avalanche Summary
No recent avalanches have been reported. However, we currently have very limited observations. If you have been out, please submit any observations to the Mountain Information Network MIN.
Snowpack Summary
Recent reports suggest there is an average of 60-120 cm of snow in the alpine. This decreases dramatically with elevation where the primary hazards are rocks, stumps, and open creeks. We currently have very limited snowpack observations, so it is critical to supplement this information with your own observations.5-15 cm of recent snow is sitting on a crust that was formed during a temperature inversion that happened last week. Surface hoar (weak, feathery crystals) that formed during last week's dry period were likely melted by warm temperatures, but may have been preserved on sheltered, north facing slopes at treeline elevations. Expect to find an early season crust near the bottom of the snowpack in many areas.
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.
