No
Avalanche Type:
Soft Slab
Size:
Size 1: Relatively harmless to people
Elevation:
Upper
Aspect:
N
Comments:
Lots of surface slides that were sort of a mix of wind slab, dry loose, and wet loose. Some propagated ~20 feet.

Signs of Unstable Snow

None reported

Observations

Snow started out dry around 10am but got quite wet by 1pm due to fog and warming temps.

Triggered a few small 1-4in deep wind slabs, but it was sometimes hard to differentiate sluffing from soft slab. In any case, these slides entrained a lot of snow even if the initial slab was quite small, ran hundreds of feet, and reached D1.5. Enough to knock you off your feet or potentially bury in a terrain trap.
