Avalanche Summary
No new avalanches have been reported in the region. However, we currently have very limited observations. If you have been out, please submit any observations to the Mountain Information Network MIN.
Snowpack Summary
Approximately 5-10 cm of new snow sits on top of a widespread layer of weak, feathery surface hoar crystals. The new snow has been redistributed by recent southerly winds. A mixed layer melt-freeze crusts and sugary facets buried late October can be found at the base of the snowpack at treeline and in the alpine. Snowpack depths taper quickly as elevation decreases. Snow depths below tree line are generally below the threshold depth to produce avalanches.
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.
