Well, we finally fulfilled the recipe for a slab avalanche. Observed some natural activity in Dutches today. SS-N-R2-D2.5-O/G in High Dutch path overnight last night. Also sympathetic releases on each side of the main path, all in pockets that face NE. Sometime around noon today SS-N-R1-D2-O/G in the goalpost area just south of conehead, with another sympathetic pocket release to the south. Impressive continuity of the weak layer and slab as evidenced by the sympathetic releases. First pics are of the overnight release, last pic is the noontime release.
