Avalanche Summary
There was recent (Dec 26) report of a size 3 skier triggered avalanche in the Dogtooth range. Triggered from a thin area on a cross-loaded west facing feature at the upper end of the tree-line elevation, it then stepped down to the early November crust. There are no other observations to report at this time.
Snowpack Summary
New snow combined with wind has formed fresh wind slabs on the surface and/or buried newly formed surface hoar in sheltered, open areas at and below tree line. The mid-pack is reported to be settling well. Recent reports indicate the late November surface hoar, near the middle of the snowpack has been inactive as of late. There has been a recent report of the early November crust, near the base of the snowpack being reactive. It's important to note that professionals are still cautious about these lingering persistent slab problems, however the likelihood of triggering is low. Be wary of steep complex terrain with a shallow snowpack, where triggering a persistent weakness is more likely
