Primary Problem: Wind Slab
Bottom Line: Human-triggered avalanches are likely on wind-loaded slopes today. Recent snow was drifted into thicker and stiffer slabs which have been easy to trigger, and will remain reactive for at least another day. Avoid slopes steeper than 30 degrees that have recent wind-loading. Seek out slopes sheltered from wind, and consider smaller slopes with clean runouts that minimize the potential size and consequences of a slide. Carefully evaluate the snowpack for recent wind-loading and buried weak layers before getting onto steeper slopes.

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’.
