Recent snow and wind have made wind slabs that will be most reactive in places they are sitting on a buried crust.
Wind from the southwest and the northeast means that wind slabs can be found on all aspects.
At lower elevations these wind slabs are on a crust, and will be most reactive where the crust is present.
A small ( size 1 ) remotely triggerd avalanche was reported at treeline elevation in this MIN ( Mountain Information Network ).
In general, observations are limited this time of year. Be sure to verify conditions as you go.
If you are getting out in the backcountry, consider making a post on the MIN.
Expect to find soft snow in only the most in sheltered areas, and wind slab on leeward slopes.
Wind has varied in direction over the past few days, expect exposed areas to be generally wind-affected.
A crust is buried from 5 to 40 cm under the new snow. The bond between this crust and the new snow is very poor.
Below ridgetops there is an average snowpack depth of 110 cm. Snowpack depth gradually thins as elevation decreases to around 60 cm at the highway.
Many early season hazards are just below the surface at this elevation.
