Two notable SS-N in Slide Canyon and Chablis from yesterday or the day before. Both on SE slopes between 10,300' and 9800' on 37-40deg slopes. Chablis ran to edge of upper bench, and Slide ran around 3,300' vert. Crowns were only 4-12" deep and 200'-300' wide. Both failed above a MF crust with cold dry stellers and some facets on the crust. The most notable thing was I felt two separate collapses as I skinned above the crown in Chablis. SE still seems like its trying to adjust!
