Comments
Group triggered in a shallow snowpack(50cm) area on a broad rib feature from uptrack. Whumpf felt, slope adjacent remoted 150m away. Impressive propogation and dry slab ran fast and far, shaking and breaking few small trees. Est 3-4m in confined runout deposit. Fracture Line profile showed avg HS of 100-120cm. Failure plane is facets on top of the October crust. Mod Compression results on this layer with a sudden planar fracture character. Slab is well settled 1F resistance new and old storm snow.
