Primary Problem: Wind Slab
Bottom Line: The snowpack is thin, but we are heading in the right direction, with 5-10” of new snow falling in our latest storm. Wind slab avalanches are the primary concern. Avoid steep slopes with signs of instability, which include recent avalanches, shooting cracks, collapsing (whumphing), stiffening of the snow surface or visual cues of drifting. Avoidance should be our objective because getting captured in an avalanche of any size will likely result in traumatic injuries. To reduce the consequences of a mistake, carry rescue gear, practice with it and follow safe travel protocols in and around avalanche terrain.

  • Cracking in recent hard wind slab

    From e-mail: "Photo attached from near top of hyalite peak, 11/2. Cracking in recent hard wind slab, I had to really jump hard to make this. Walked on many other hard slabs that were well bonded. Highly variable snowpack. I think you'd be most likely to get into trouble by popping out a small hard slab pocket like this and getting magic carpeted into some thinly covered terrain." Photo: B.

    From obs: "1-3 mm faceting in front of the Montage. Clear skys and mid 20 temps"

The Last Word

Read accident reports from previous early-season accidents before you venture to the snowy hills. This accident report from October 2012 in the northern Bridger Range, and this report from the tragic fatality six years ago in early October are reminders of the potential consequences of even a small avalanche.
