Looks like the first 12” or so down there was on the more moist/dense side before winds backed to 020? Beyond that, I’m not going to pretend to know what it’s like to experience 4”/hr with a 40-50kt wind. I would think in theory the dendritic structure takes a mechanical beating, but when it’s snowing that hard I can imagine it almost accumulating too fast for the wind to entirely mess with.
But I’m up in CAD land where the snow prefers to fall and land gently. I had barely any wind in my 34” in 12hrs in Dec 2020. I think you could’ve sneezed on the pack and knocked it down 5”.
