Snowpack Summary

Around 15 to 30 cm of snow since Saturday rests on a hard melt-freeze crust. Recent south to west wind may have blown the snow into lee terrain features in wind-exposed terrain at high elevations.

A couple weak layers of surface hoar and/or faceted grains associated with a crust from late January and mid February may be found 40 to 60 cm deep.

The remainder of the snowpack is strong.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Use ridges or ribs to avoid areas of wind-loaded snow.
