A surface crust has made for generally safe avalanche conditions.It's good practice to still carefully evaluate your line and the snowpack before committing to high consequence terrain.

Avalanche Summary

A few small (size 1) wet loose avalanches occurred on Monday, no recent avalanches have been reported.

Field observations have been very limited, if you head into the backcountry please consider submitting your observations to the MIN.

Snowpack Summary

A dusting of snow may be found sitting on a thick and widespread melt-freeze crust. This crust may soften and melt on lower elevation slopes and on sunny slopes if the sun comes out for periods of the day. High-elevation northerly alpine slopes may still have dry snow.

Cornices are large this time of year and may become weak with daytime warming. They should generally be avoided.

Otherwise, the snowpack is generally strong and well-bonded.

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Make observations and assess conditions continually as you travel.
  • A crust on the surface will help bind the snow together, but may make for tough travel conditions.
