Snowpack Summary

Strong SW winds with extreme gusts contributing to Windslab development on Thursday. These new Windslabs sit over 10-15 cm of faceted powder in the alpine and at treeline. Surface snow below treeline is mostly unaffected by wind. The midpack is generally strong in thick snowpack locations, and is bridging weak basal facets.
