Avalanche Summary

A large (size 2) natural slab was reported on Tuesday, failing on a sun-affected slope. Skiers also ski cut a few small wind slabs in wind-affected terrain.

On Sunday, explosive control in the Duffey area produced several large (size 2-2.5) wind slab avalanches that failed on the weak layer below the storm snow.

Snowpack Summary

30 to 50 cm of snow fell during last weekend's storm. This snow is slowly settling and remains dry and powdery due to the cold temperatures. Upper elevations have had some wind-effect and wind slabs may be found near ridgetops.

The accumulated storm snow is sitting on a weak layer that developed in late January. In most areas, this layer consists of a hard slippery crust. However, on shady, upper-elevation slopes, the new snow may be resting on faceted grains or surface hoar.

The mid and lower snowpack is well-settled and bonded with no other layers of concern.
