We toured up Green Butte ridge to observe the winds and look for signs of lingering wind slabs. Snow surfaces are a mixed bag of textures, including packed sastrugi, sticky butter, and smooth melt-freeze. The strong wind has blown dirt and tree debris across the surface of the snow. Despite the strong winds, the temperatures were warm and melting the upper snowpack. Smooth spring-like conditions were found on protected southerly aspects.
