In sintesi

Watch for stiff, wind-loaded snow in open terrain and below ridge crests.

The best riding will be in sheltered terrain at upper elevations, the biggest challenge will be getting to it.

    Strong winds will impact loose snow in open treeline features and at higher elevations. Watch for stiff, wind-loaded snow on ribs and gullies, especially where it sits over a weak, sugary layer near the base of the snowpack.

Avalanche Summary

No new avalanches reported. If you are out and about in the mountains, please consider posting your observations to the MIN.

Snowpack Summary

Isolated flurries and wind have produced a variable snowpack. At upper elevations, winds have exposed rocks and left dense wind slabs in open terrain; softer snow is found in sheltered and lower elevation locations. This overlies a crust that formed in mid-November, buried 30-50 cm deep. The lower snowpack consists of multiple crusts, and in some areas, a layer of weak, sugary facets can be found near the ground.

Total snowpack depths range from 30 to 100 cm, tapering quickly at lower elevations.

In many areas, especially below treeline, there is not enough snow to smooth out surface roughness or reach the threshold needed for avalanches.

Terrain and Travel Advice

  • Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
  • Watch for areas of hard wind slab on alpine features.
  • Be cautious of buried obstacles, especially below treeline.
