Snowpack Summary
The valley bottom is still challenging travel due to the minimal amounts of snow. At 2200m, there is about 100cm of snow at the most, of which the bottom 60cm is comprised of facets. . Somewhere around 2350m, the snowpack increases a bit and has a supportive midpack. This midpack was mostly formed by the numerous winds slabs that have bonded over the last few weeks. The wind has been blowing strong from the West for three days, depositing a solid wind slab on the surface in most of the alpine. Please watch the bulletin closely over the next few days as the forecast snow on Friday and Saturday will most likely increase the avalanche danger to High.
