Avalanche Summary
On Thursday, numerous loose dry avalanches up to size 1 were reported on all aspects at treeline and above. Two skier triggered slabs were also reported on a steep southwest aspect at 1800 m. These failed at a crust interface 20-25 cm down producing size 1 avalanches. Check out this recent MIN report from GIN Peak.
Snowpack Summary
Up to 10 cm of new snow sits above a variety of old snow surfaces including firm wind slabs, sun crust on steep solar aspects, surface hoar and faceted crystal in sheltered areas. The recent low-density snow will likely have a poor bond to the previous snow surfaces and sluff easily from steeper terrain features. The lower snowpack is generally strong and settled.
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.
