Snow surface

Crazy snow storm last night.... 12" low density snow in the DOT weather station parking lot but only 6-7" on the ridge. We are quite sure that this is true despite the winds. There was minor to moderate wind effect on Seattle Ridge but looking across to Magnum and Sunburst it seemed they got less snow and more wind - scoured ridges.


Storm snow seems to have bonded well with preexisting surface at treeline and below.

Lower elevations - 1,900': Bottom 4-6" of snowpack has patches of weak snow near the ground

Top of treeline - 2,300': Weak layer of facets and buried surface hoar from Nov 16th. This layer was 18" below the surface. See video
