Snowpack Summary
Up to 5cm of snow covers a widespread layer of surface hoar above a crust that extends all the way to ridge crest. The curst is effectively "capping" the snowpack and doing a good job of protecting the buried weak layers bellow. However, I suspect that the mid-January surface hoar layer could still produce an avalanche if given a large enough trigger in the right spot. It can be found down about 1m in the alpine and 50-60cm at treeline. The mid-December crust/facet/surface hoar weakness may persist in the mid to lower snowpack at higher elevations.
