Snow Profile Comments
Snow pit dug on a similar aspect and elevation ~400' adjacent to the avalanche in a more heavily treed area with less wind-deposited snow.
Comments
No tracks entering the slope. Potentially a remote trigger yesterday (Dec 1st) by one of the many passing riders on their way to the summit. Although this avalanche location is the obvious and frequent starting zone for the area, it is important to note that the snowpack is still very shallow in these lower elevation areas, with plenty of nasty logs and rocks to get hung up on.
Below the ridge line and within wind-sheltered trees, the new snow is not propagating much farther than the length of the ski. On the slopes we skied today it was possible to produce ski-width slabs on small test slopes but nothing more.
