None reported

Observations

Saw the large reported crown off Roosevelt and one party headed up near it towards holy diver. Found widespread weakness on nw aspects, 1 about 6 inch down and another about 6 inches. Approx 2 feet down was a graupel layer. We could collapse the whole slab on acute kick turns. We bailed from original plan and skied cupcake which was pretty wind affected and Bryant's which remained sheltered. Photos showing the 2 distinct slabs and then the cohesive deep slab. No slab was highly reactive, required a fair amount of force and didn't propagate. Snow seemed to bridge laterally well but given the large crowns nearby decided it wasn't logical, and the snow was of poor quality anyway.
