Nice, late fall day with temperatures warming up enough to melt snow surfaces on neutral aspects below 3,500ft by afternoon.

We found a breakable rain crust on the surface from Smithbrook TH that extended up to ~4,200ft. Above that it tapered off to soft powder. Around 4,500ft we began receiving some direct feedback in the form of Whumphing. We found the culprit to be a thin layer of faceted grains and/or surface hoar on top of a friable crust, over a thicker layer of very weak, sugary facets. This layer can be attributed to the high pressure spell in November. We found this structure from 4,000ft up, and likely extends to ridgeline but we couldn't verify as we turned around due to obvious poor stability and recent avalanches. Whumphing and cracking became more frequent as we approached our high point at 4,800ft. We verified that the slides we saw were failing on this weakness with a profile, then skiied carefully through the thin cover and forest back to the road.
Layer Depth/Date: 12"
Comments: May turn into a persistent slab problem with more snow.
