Avalanche Summary

We haven't received any reports of recent avalanche activity.

Please consider sharing your observations to the Mountain Information Network.

Snowpack Summary

Around 5 to 10 cm of soft snow overlies a hard melt-freeze crust above 1200 m on northerly aspects. The crust is on the surface on sun-exposed slopes and below 1200 m. The crust will transition to moist snow with daytime warming and freeze back into a crust overnight.

Cornices are large and looming at this time of year.

Terrain and Travel Advice

  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
