Avalanche Summary

An avalanche was reported around Zupjok on Monday, read the full report here

Whumpfing near Zoa peak was reported on Saturday where there was a slab (stiff snow) over the weak layer. Small skier triggered sluffs were also reported in steep terrain on Saturday.

Snowpack Summary

15 cm of new snow fell on Saturday. This snow is wind-redistributed by northeast winds in the alpine extending well into treeline.

40 to 60 cm deep is a weak layer that was buried at the end of January. In many areas, this layer consists of a hard crust. However, on sheltered, upper-elevation slopes, the new snow may be resting on faceted grains or surface hoar. This layer hasn't produced any recent avalanches, but may be a problem when it snows again.

A crust from December is buried 80 to 120 cm deep and may have facets around it in shallow areas. Otherwise, the lower snowpack is well consolidated.

Terrain and Travel Advice

  • Make observations and continually assess conditions as you travel.
  • 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.

Avalanche Problems

Wind Slabs

Watch for slopes where slab properties exist. It is possible to have avalanches step down to the underlying weak layer.
