Notes

From obs: "Natural wind slab, likely triggered by cornice fall in the last day or two, on a NE aspect at 8500’. Propagated ~150’ wide and ran probably 300’. Slab thickness seemed to be 18-24” at the thickest. No sign of stepping down deeper into facets in the snowpack, although adjacent to this slide there was evidence of an older slide (previous to recent storm cycle) that failed deeper in the snowpack."
