January 31, 2019 View this post on Instagram Incredible day in the #FRange with @bald32. We put in a big survey of the terrain post active weather the past week. Red flags observed today included active wind loading from moderate outflow northerly winds (as seen in the pluming off peaks in some of these photos) and some very concerning stability test results related to faceting around buried rain and melt-freeze crusts mid snowpack (more details on that in a follow up post). We observed a few recent D1 wind slabs on westerly aspects, a few recent D1 loose snow avalanches (sluffs) on steep northerly terrain, and a few older (48+hr) and larger (D2) persistent slabs that likely failed during stormy weather earlier in the weak when they became overloaded by new #snow and wind. There are definitely DEADLY PERSISTENT SLABS LURKING. Terrain management is the name of the game. Stay tuned for more on the current state of the #snowpack as the weekend approaches. #FRangeLove #Randoism #CelebrateCreation #EarthEcstasy A post shared by Anchorage Avalanche Center (@anchorage_avalanche_center) on Jan 31, 2019 at 7:57pm PST View this post on Instagram Upper Rabbit Creek and South Fork Campbell Creek stability tests today provide further evidence of serious persistent slab #avalanche concerns related to nasty persistent weak layers: significantly faceted snow around a buried rain crust mid #snowpack and depth hoar near the ground.
