Snowpack Summary

Up to 30 cm of new snow has accumulated in the past week. Southwest wind on Sunday will continue to redistribute new snow in wind-exposed areas.

Roughly 40 to 60 cm of snow now overlies a variety of old surfaces, from surface hoar and facets in sheltered terrain, a thin sun crust on south-facing slopes, and firm, previously wind-affected surfaces at higher elevations.

The mid and lower snowpack includes various crust layers from November.

Snow depths at treeline vary from about 60 to 120 cm and decrease dramatically at lower elevations.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Be cautious of buried obstacles, especially below treeline.
