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.

  • We triggered this small avalanche on a steep windloaded rollover on an otherwise mellow slope. This avalanche was 15-20' wide, 8" deep, and ran for about 30-40 vertical feet. The skier easily skied away from the slide and was not caught. Photo: GNFAC

  • On my drive to Cooke City I saw old slab avalanches in YNP near Mammoth and on Abiathar and Ampitheater among other places. These appeared to have happened earlier in the week.

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!
