It was extremely windy today. Large plumes of blowing snow were streaming from the upper mountain. Snow surfaces are a mixed bag of textures. Below treeline host breakable melt-freeze crusts in protected areas. Firm supportable surfaces dominate as well as chalky previously wind-transported snow. Near and above treeline terrain is very wind affected and largely scoured. Firm windboard and sculpted sastrugi features exist on the remaining ribbons.
