Snowpack

Snowpack: The snow from December storms has faceted into .7 to .1 mm, fist hard facets on all aspects. This layer is uniform and about 25 to 30 cm thick on East to North to West aspects, and sits over larger depth hoar grains on NE to NW aspects. On southerly aspects, the facets surround or are capped by one or two melt-freeze crusts. On steep, due south, the crust is >10 cm thick and generally goes to or near to the ground; lower angled south has a crust/facet sandwich. On SE and SW aspects, the surface crust thins towards a fragile, soft crust that is <1cm thick. Long story short, there are concerning persistent weak layers at the snow surface on all but due south BTL here…this will be the 12/23 interface. This layer isn’t as large-grained and fragile as the 12/6 layer, but it will certainly cause issues, and it spans more aspects than the 12/6 layer.
