Snowpack Summary

Surface: Lingering isolated wind slabs above 2000 m where snow remains dry. At treeline and below (2000 m and lower) the snowpack has a frozen surface crust.

Mid- and Lower-snowpack: Below the most recent snow the layers are well-settled. There may be some weaker layers but it seems thick frozen crusts are effectively capping them.

Snowpack depths are roughly 150 cm cm at treeline and tapers rapidly below 1500 m. This is about 60% of an average year.

Weather Summary

Wednesday Night: Trace of new snow. Clearing. Cooling with alpine temps around -5 to -10 C. Light westerly wind.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.

Problems

Wind Slabs
