Primary Problem: Wet Snow
Bottom Line: Warm temperatures, wind-loading, and the possibility of rain and snow later in the week will drive avalanche problems. Wet snow avalanches will be the primary concern on most slopes. Get on to the snow early in the day when surface-level crusts are supportable and get off when the crust breaks down and more than the upper few inches of snow become slushy and wet. Relatively small wind-slab avalanches are possible on upper-elevation slopes that remain shady and cool. If the upper snowpack is dry, dig down and back off steep objectives if you find instability in your tests, observe shooting cracks or indications of fresh wind-loading. Reevaluate conditions when a mix of rain and snow moves into the area on Thursday and Friday.

  • Saw what looked like a wet slab avalanche from the road along the Madison River.  Roughly north facing slope at 7500'.

  • 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

  • A small avalanche was seen in Black Bear Canyon on 01/14. This was a recent avalanche that happened today or yesterday 01/13.

  • 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."
