Triggered this pocket sympathetically from below while on an up track I rarely use, beneath the cliffs of Holy Mole. I was skinning on lower angle terrain, in sparse trees, below this steep rollover. I had skied Holy Toledo, which was generally scoured, so I was surprised by the depth of the slab but in the photo you can barely see the erratic winds loading snow (graupel) over the convexity. I suspect this avalanche ran on the 28th's rain/rime crust.

Forecaster Comments: I happened to be traveling though the area with Rick shortly after, and we went up to the crown. We got a small collapse directly beneath us as we traveled across the debris. Evelyn Lees

Forecaster comment: The bed surface had so drifted in that we couldn't tell if the slide had occurred yesterday or today - it was actually only about an hour previous. Strangely, the new pooled snow/drifted snow cracked. Evelyn Lees

Forecaster Comment: In the area of the crown I looked at, the weak layer was about 4 inches (10 cm) below the Dec 28 rain crust, in a band of very weak facets. Evelyn Lees
