Avalanche Summary

No new or recent avalanches have been reported, however there are very few field observations coming from this forecast area.

If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

Roughly 5-10 cm of new snow fell in the region in the early week. It added to an existing skiff of snow atop a widespread crust presently found at or near the surface below 1400 m. South facing slopes are generally scoured.

The snowpack is generally shallow and faceted (weak, sugary) with multiple crusts in the mid snowpack. Pockets of deeper, wind-loaded snow may be found near ridges, gully features, and established avalanche paths.

Average snowpack depths at treeline are roughly 20 to 80 cm.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Expect shallow snow cover that barely covers ground roughness.
  • Avalanche danger is often elevated in alpine gullies where snow has accumulated.

Problems

Wind Slabs

An icon showing Wind Slabs

Light new snow amounts and variable winds likely formed small wind slabs across a range of aspects. Older, harder, more stubborn wind slabs in gullies likely sit on weak, faceted basal snow.

Aspects: All aspects.

Elevations: Alpine.
