We've had no reports from the upper elevations of the Provo area mountains but extrapolate that mid and upper elevation snow structure is poor and potentially unstable on steep northwest to easterly facing slopes. The Thanksgiving storms are now a thick slab overlying weak old snow from October and this structure continue to cause avalanches in the Salt lake mountains. Extra caution is warranted in steep shady terrain.
The video below (link) further illustrates our primary avalanche problem.
It will take patience while allowing time for this layer to heal, and this layer may become increasingly active later this weekend with an additional load of snow and wind. Remember, existing tracks on a slope are zero indication of stability. For now, I am avoiding all steep northerly aspects.
