Snowpack Summary

The storm snow from earlier in the week has been redistributed by winds to form alpine windslabs. More recently, the warm temperatures have also promoted settling of the treeline snowpack. At the moment windslabs are the main concern, especially considering the variety of surfaces below. Facets and crusts tend to be the deeper layers right now. As for depths, the stations are showing about 40cm at treeline and more in wind loaded areas.

Problems

Wind Slabs
