Dangerous wind slabs above Marion Lake

We found sensitive storm slab, loose snow, and wind slab instabilities large enough to injure or bury you, mostly at upper elevations.

• 2" to 4" of new snow.  Light winds with strong gusts, mostly from the southwest. Blowing snow at times.
• In wind protected mid and upper elevations, we skier triggered numerous shallow storm slabs and sluffs (2" to 4" thick) that broke on low-density snow at the start of the storm. These ran up to 700 vertical feet and entrained enough snow to bury or injure someone in a terrain trap (D1 to D1.5). We also saw a similar natural slab avalanche.  
• We skier triggered several thicker wind slabs (6" to 24" thick) on cross-loaded SE aspects above 6000', D1 to D2 in size.  We observed shooting cracks and one large collapse in wind drifted snow, failing on low-density storm layers.
