Primary Problem: Wind-Drifted Snow
Bottom Line: New snow and wind-loading are the main avalanche concerns today. They are creating instability in the upper 1+ foot of the snowpack, and the weaker, faceted snow near the ground is more difficult to trigger, but not impossible. Rocks sticking out in starting zones indicate shallow areas where a person could trigger a large and deadly slide. Today is a day of active loading and the snowpack will be most sensitive to triggering, both naturally and by people. Dangerous avalanche conditions are back. Be careful getting near avalanche terrain and be especially mindful of terrain traps.

  • Skiers a few days ago saw several deep natural avalanches near the head of Swan Creek. These avalanches broke 2-5' deep, 2000' wide, and ran "full track". The exact date of when these avalanches happened is unknown but they likely happened over a week ago in the first few days of March. Photo: S. Reinsel

  • Riders saw a large crack in the snow near the Cabin Creek Cabin in the S. Madison Range. This is a red flag for unstable conditions. Anonymous

  • Photo and observation from 01/20

    From obs: "Large roller balls were observed in avalanche terrain on a SE aspect at 8,300'. Alongside this observation, rather wet, sticky snow was observed throughout the tour, causing multiple glopping incidents on our skins." Photo: E. Webb

  • 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."
