Recreational Observation


Dec. 15, 2016, 10 a.m. PST

Weather: Cold!

Snowpack: The 12/8 interface is easily discernible, visually in pit walls, as well as in tests. It is generally down about 35 - 50cm, depending on aspect and elevation. Over the past few days, it has been unreactive to ski testing and has not produced results in column tests on a variety of aspects. Grain type seems to be mostly DF's overlying small faceted grains. Many skiers have travelled steep terrain in the Above and Near Treeline zones over the past week with no signs of instability at the 12/8 interface. It is worth noting that there is little to no travel by backcountry skiers happening below approximately 4000' due to lack of snow. Of concern is the potential return to zonal flow and normal temps. after the weekend. Snow surfaces at all elevations and most aspects throughout the area are very weak. Depending on aspect, it is a mixed bag of small SH, large DF's, NSF's and very weak crusts. Incredible skiing, for now...

Area Description: WA Pass Environs

Avalanches: No recent activity observed, other than skier and solar initiated Dry Loose and very small, isolated WindSlab on 12/14 that was reactive to ski cuts. Older WindSlab that formed on 12/10 in the alpine is buried and unreactive to skiers.
