Primary Problem: Wind Slab
Bottom Line: Wind slab avalanches are the primary concern through the weekend. They could break under the snow that fell yesterday or in the new snow that is going to fall and be blown around tomorrow and Sunday. Either way, they could easily have enough power to knock you off your feet and into the plethora of rocks and stumps that are still exposed with a thin, early season snowpack.

  • 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.

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.
