Avalanche Summary

On Friday and Saturday, numerous natural as well as skier- and explosive-triggered wind slabs were reported size 1-2. Most were in reverse-loaded lees of ridgetop on west to southwest aspects at alpine and treeline elevations.

Snowpack Summary

New snow falls with wind over generally soft, faceted and/or moderately wind-affected surfaces.

A right-side-up upper snowpack appears to be bonding well to a crust buried 70 to 100 cm deep. The mid and lower snowpack is generally well-settled and bonded with no deeper concerns.
