A skier in Hyalite observed several day-old wind slab avalanche near the top of Flanders, and noted "small rolls above the glade and up to ridgeline were still cracking under the weight of a skier." Another reminder that recently wind-loaded pockets are reactive throughout the advisory area. Photo: G. Antonioli
