Avalanche Summary

On Wednesday, there was a widespread avalanche cycle. With natural and human-triggered avalanches reported up to size 3.
Snowpack Summary
40 to 50 cm of snow has fallen this week, with some areas in the west receiving up to 70 cm. This soft snow is being redistributed by a west-southwest wind in the alpine and open treeline.
A surface hoar layer formed in early December is now buried 50 to 90 cm and is most prevalent between 1700 to 2200 m. So far, this layer hasn't been reactive, but it's worth keeping on your radar.
