Avalanche Summary

No recent avalanches have been reported.

Please consider submitting your observations to the Mountain Information Network.

Snowpack Summary

10 to 20 cm of soft snow is covering a hard crust. At upper elevations, this newer snow has been blown by moderate winds, creating wind slabs on lee north and west facing slopes.

Depending on how much new snow falls during the storm on Saturday, these slabs may remain rider-triggerable for a few days.

The mid and lower snowpack are not concerning at this time, and are made up of various hard layers and crusts.

Terrain and Travel Advice

  • A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
  • Be careful as you transition into wind-affected terrain.
