Comments
We did several hasty pits and could not find any density inversions within the storm snow, but on a wind-exposed slope at 9,500', we were able to get cracking in the 15-30 cm thick soft wind slab, where the adjacent slope had already avalanched. The recent storm snow had bonded well to the old snow surface, and we could not find any faceting from the layer of near-surface facets on mid and upper-elevation northerly slopes that were buried on Tuesday.
We traveled with a Considerable danger mindset, and avoided steeper terrain, especially in areas that were wind-loaded.
