Primary Problem: Persistent Weak Layer
Bottom Line: You can easily trigger wind slab avalanches large enough to bury a person which break below thick drifts of yesterday’s snow, and you can trigger potentially larger persistent slab avalanches that break on weak layers deeper in the snowpack. Persistent slab avalanches can break hundreds of feet wide and can be triggered from lower angle terrain connected to slopes steeper than 30 degrees. Your safest choice is  terrain that is less than 30 degrees steep, and not connected to or below anything steeper.

We received a vague report of a partial burial in the Lionhead area after a snowmobiler unintentionally triggered an avalanche. The slide was reported to a homeowner near the Denny Creek trailhead. The homeowner is friends with several members of Fremont County search and rescue. One of which happened to be with GNFAC Forecasters today.
