Assess steep lines for wind slabs before committing.

Winter conditions still exist on high north facing terrain.




Avalanche Summary

Several natural, explosive and skier triggered wind slab avalanches were reported on Sunday. These avalanches were in exposed terrain at treeline and above.

If you have any recent photos or observations, please submit them to the Mountain Information Network, observations are limited in the spring.

Snowpack Summary

On high north facing terrain up to 20 cm of dry snow may be found.  A new crust will likely be found on all other aspects and elevations. This crust will likely become moist throughout the day with rising temperatures and solar input.

Below treeline terrain is snow free or has very low snow cover. Travel conditions are challenging with exposed rocks, stumps, and open creeks.

Terrain and Travel Advice

  • Avoid freshly wind loaded terrain features.
  • Avoid sun exposed slopes, especially if snow surface is moist or wet.
  • Expect shallow snow cover that barely covers ground roughness.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
