Primary Problem: Persistent Weak Layer
Bottom Line: Avalanche conditions are dangerous and large, human-triggered avalanches are likely. It remains important to stay diligent with conservative terrain choices and careful route finding. With recent snow and multiple widespread buried weak layers making complex snowpack stability, travel advice is to simply avoid slopes steeper than 30 degrees and flatter runout zones below.

  • From IG on 12/10: "2 slides we triggered remotely in tepee yesterday"

  • From obs: "Dug into the hillside right before going up the creek. Snow pack was 75 cm deep consisting of three layers. Bottom 35cm is obviously faceted, grain size is around 2mm. Very thin ice crust at around 35cm. Upper 35 cm of snow is brand new snow from this current storm, precipitation particles, low density, with minor wind effect. Performed a quick Compression Test and the ice crust layer failed on the second tap." Photo: S. Gralla

  • From IG: “Pine creek today, some small wind slabs and a full depth wet slide off black mountain”

  • From IG: “Pine creek today (10/21), some small wind slabs and a full depth wet slide off black mountain”

  • From obs. "Was out alpine climbing today and observed the north face of Blackmore had slid already."
