Continue to make conservative terrain choices and consider the consequences of a chosen slope avalanching. There is variability in the snowpack throughout the region but what is consistent is that the snowpack is shallower and weaker than average.
Wind slabs will likely still be reactive to rider traffic on west,north and east aspects.
Be aware that wind slabs can step down to deeper layers.
There are 2 concerning weak layers in the top meter of the snowpack. The first is a layer of surface hoar down 20 to 40 buried in early January.
The second is a layer of surface hoar, facets and/or a crust may be found around 40 to 70 cm deep, which is a prime depth for human triggering. both these layers are most concerning at treeline and below.
A weak layer near the base of the snowpack, buried in November, remains a concern despite lack of recent avalanche activity. Human triggering of this layer remains possible, especially in shallow areas with variable snow depths.
On Friday ski cutting produced small wind slabs on west, north and east aspects.
On Thursday a skier was caught in a small avalanche at treeline. This avalanche failed on a layer of facets in the upper snowpack. Check out the MIN for more details. A few other similar sized skier triggered avalanches were reported in the region. These other avalanches failed on facet or surface hoar layers in the upper snowpack.
Please continue to share any observations or photos on the Mountain Information Network.
New wind slabs can likely be found on exposed treeline and alpine terrain on west, north and east facing slopes. As the freezing level falls the surface will develop a crust at lower elevations.
There are 2 concerning weak layers in the top meter of the snowpack. The first is a layer of surface hoar from early january and the second is a layer of surface hoar, facets and a crust from late December. Both these layers are most concerning at treeline. There is also a layer of facets at the bottom of the snowpack that will likely persist for a prolonged period of time.
In General the snowpack is shallow and weak.
