Primary Problem: Wind Slab
Bottom Line: Wind slab avalanches are the primary problem resulting from increased winds from the west yesterday and this morning. Today winds will increase a bit more and shift to the south. The size, distribution, and sensitivity of these wind slabs will increase throughout the day. Persistent slab avalanches remain on our radar because there is a widespread layer of weak, faceted snow that formed in late January. This layer is buried 1-3 feet deep and seems to have been unreactive in recent days

We saw this today after it happened. Looked like a snowmobile triggered it. I believe it is mostly south facing. Thanks.

Plenty of wind slabs ranging in size on Lionhead ridge and on surrounding slopes. Noticed a few natural slides on the way in, a few more on the way out that were rider triggered. Snow was quite wet by this afternoon @8500’.
