General Comments

Saw the flanks of a recent hard slab release south of Snow Canyon today. The winds were blowing a little and it was snowing lightly, yet the crown looked very clean. We were several hundred feet away from it, so I am guessing at the details. Looks like it may have stepped down below the MLK crust in places. Intentionally initiated several fast and long running sloughs in new snow on an east facing slope. Saw evidence of natural sloughing, very fresh, on east facing steep slopes. Poor visibility limited photo quality.

Long running sloughs.

Hand pits indicated moderate adhesion of a slab sitting on the frost layer above the MLK crust.
