Avalanche triggered just on leeward side of subtle cross-slope rib. While travelling and probing I felt a subtle density change within underlying storm snow, stoped and dug a test pit: ECTP6 27cm down under subtle denser layer of wind deposited snow. Stomp with ski a few feet further out from rib resulted in crack propogating across slope. 8-12" crown propogated ~75' out across slope. R2-D2. Couldn't tell how far avalanche ran as it went out of site over convexity.
I didn't find concerning snowpack structure or signs of instability anywhere before this point on my ascent today, besides the obvious heads-up of snow blowing that kept me keenly alert and on the look-out.
Periodic snowfall reaching S1-2 throughout day, W winds with moderate gusts in exposed areas below tree line and above. ~3-4"+ new snow from last night / today in sheltered areas, wind filled in skin track and other tracks where exposed quickly.
