Chilkat Pass Zone: Noticed D1-2 R2 surface wind slab avalanches on steep walls above the glacier SE-E-NE-aspects 5,000-6,000'. Fresh 100' wide pocket a few inches deep ran 800' from 5,800 - 5,000' over a ski track traverse on a 45-degree SE-aspect slope.

Good riding quality above 2000ft in the Ripinsky, Jones Gap, and 3920 / 7-mile saddle areas today. Toured multiple aspects in multiple basins and only found one area of clear red flags: some cracking/sliding of recently wind loaded soft slab in one pocket. As a result, there were more wind loaded areas that we avoided. Backed…
