Unsure on the exact location, aspect, and elevation. The published data is fairly accurate. Based on the characteristics and similar activity occurring on the same day, we are calling this a persistent slab avalanche that likely failed on facets or a facet+crust combo buried below the storm snow from the past week. From the observers' report: "We were playing on a 200-300 yard north-facing steeper area with a large runout and triggered an avalanche. Multiple people had been riding up and down the slope for 15-30 minutes. It was around 2:00 and the snow was heavier in this area. We did not go up to the crown, but it appears to have broken deeper below multiple storm layers. We did not see any other avalanche activity. The crown was approximately 100-150’ wide and looked to be 2-3’ deep and ran out 100-150 yards." 4/10 weak layer strongly suspected.
