Primary Problem: Wind Slab
Bottom Line: Fresh wind slabs are the main avalanche problem especially by Sunday when strong winds should blow from the west. Early-season avalanches may not bury you, but they will hurt playing pinball with you through the rocks and stumps. Hunters should be especially cautious since they often travel alone and without avalanche rescue gear. Avoid steep slopes with snow deeper than your ankles.

  • 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.
