Primary Problem: Wet Snow
Bottom Line: Daily forecasts are done for the season, but avalanches will continue. Remain diligent with your snowpack assessments and route-finding, and adapt your decision-making to changing conditions. On Monday and Tuesday, wet snow avalanches are likely. The snow is unstable on a spectrum, from when the upper few inches of the snowpack are wet and slushy to the entire snowpack being unsupportable. Avoid steep slopes and runout zones where these scenarios are present. Beginning Tuesday night, as snow returns to the area, watch for signs of instability within the new and wind-drifted snow, such as shooting cracks, and dig down until you find a supportable crust to test for instability above this level. Avoid steep slopes where you find instability.

Relevant Avalanche Activity

Northern Madison
Taylor Fork
Remotely triggered, wet slab avalanche in the Taylor Fork
Incident details include images
Taylor Fork
WS-AMr-R2-D2-O
Elevation: 8,600
Aspect: E
Coordinates: 45.0607, -111.2720
Caught: 0 ; Buried: 0

From IG: A group of riders noted very wet snow west of Cabin Creek and Southwest of the Taylor Fork. They were sinking to the ground where it was unconsolidated. The group remotely triggered a wet slab avalanche from the ridge top. There were shooting cracks that connected their location to the avalanche. This is an interesting of persistent weak layer and wet snow avalanche problems.

  • On 2/18/24 near Buck Ridge and Muddy Creek we saw at least eight recent avalanches that occurred at various times over the last 1-3 days, natural and/or remote triggered by riders. A group in the parking lot mentioned seeing many slides actively happen in this area on Friday 2/16. Most were 2-3' deep hard slabs, ranging from 50'-500' wide. Photo: GNFAC

  • An avalanche we either triggered from 750-800 feet away or it broke naturally. This avalanche happened when we were riding near the larger of the two avalanches from yesterday, on the south side of Cedar Mtn. It was a wind-loaded slope, actively loading. The avalanche was ~130' wide with 100' of 4-12" deep new snow/wind slab and 30' wide broke almost 3 feet deep on weak snow near the ground. Photo: GNFAC

  • From BSSP on 2/17/24: "Midafternoon we received another report of a skier triggered avalanche in the Lone Lake Circe, specifically The Mullet. The reporting party contacted several ski patrollers via cell phone and confirmed that nobody was injured or had taken the full ride. This avalanche failed near the ground on a high elevation NW facing slope with the weight of a single skier with an estimated size of HS-ASu-R3-D2.5-O."

The Last Word

We began our daily forecasts on December 7. 130 daily forecasts and 464 reported avalanches later, we wrapped up our daily forecasting season on April 14th. While avalanches remain a concern until the snow is in the rivers, read our SEASON SUMMARY to look back at the heart of the 2023-24 avalanche year.

Additionally, please join us in congratulating Doug Chabot on his retirement from the GNFAC after 29 years of forecasting and 25 years as the center’s director. Thank you for everything, Doug!
