#SoFo obs today: nasty remote triggered persistent slab in Swiss Bowl today. Triggered from valley flats and ripped out the entire #snowpack from about half the bowl (HS-ASr-D2.5-R3-O failing on depth hoar near ground). Observed recent D2 natural persistent slabs from #snow yesterday and #wind today. Considerable #avalanche danger exists.
