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.

Cabin Creek
Whumpfing in Cabin Creek
Cabin Creek
Coordinates: 44.8949, -111.2280
Caught: 0 ; Buried: 0

From obs: "We were skiing out of the Cabin Creek cabin over the weekend, mostly in the low angle terrain around Skyline Ridge. Throughout the storm on Saturday and after the clouds cleared on Sunday we experienced consistent whumpfing while breaking trail. Some were larger and some were smaller, usually triggered by the person breaking trail but some of the larger ones were triggered by the second or third skier in the track."

  • We rode into Tepee Basin and saw two recent avalanches on 3/2/24. This one looked like it maybe happened yesterday, on a heavily wind-loaded slope below some cornices, 2-2.5' deep and 250-300' wide. Photo: GNFAC

  • Skiers on 03/02/2024 saw a natural avalanche on an east-facing slope and broke 3-4' deep and 100' wide. This avalanche likely happened in the last 24 hours. Photo: A. Faulkner

     

  • We noted a relatively small avalanche on the wall of Sage Basin that failed naturally within the storm snow. Photo: GNFAC

  • Skiers on 02/22/2024 observed an old avalanche that appeared to of been natural that happened sometime last week near 02/15 -02/16. Photo: H. Bigos-Lowe

  • The skillet slid sometime recently. Based on the snow on top I'm guessing Thursday-Friday last week (Feb 15-16th), but it could have happened up to a week earlier. Broke ~2 ft deep, 150 ft wide, and it was hard to tell how far it ran, but I'm estimating 200 vertical feet. Photo: GNFAC

  • From obs: "We heard numerous large-scale collapses and witnessed the development of propagating tensile fractures on a 20°-25° slope along the skin track.... We skied this location 4 times this week. Each time, we experienced collapsing and fracturing within the snowpack. and stuck to skiing conservative, low-angle lines." Photo: T. Kalakay

  • From email: "A friend and I were riding in lower Tepee today, staying on low angle terrain because of the current avalanche conditions. When side hilling on a 24 degree slope, I saw cracks shoot out approximately 100 feet around me. It was a smaller slope, but things are still pretty sensitive. This was a north facing slope in a valley that shouldn’t have been too wind loaded. " Photo: J. Norlander
