Bottom Line: Spring weather can be highly variable and create a mix of avalanche problems to watch out for. Snow conditions and snow stability can change drastically from day to day or hour to hour. Anticipate rapid change and plan accordingly. Plenty of snowfall over the winter with more spring snow to come makes avalanches possible into summer.

  • From obs 5/23/24: "Toured to the top of PK during today’s storm. Snow was very wet and heavy. We saw no other slides or signs of instability on the way up. Coming down skiers right of flippers, all 3 of us caused small slides and cracking within the new snow. I triggered the largest slide, which was 6-8” deep and 12’ wide." Photo: T. Jordan

  • On 5/4/24 Skiers triggered large wet loose slides on the Fin near Cooke City

  • 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

  • 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."
