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.

  • From IG message: “Rode the banana today.. lots of fast moving sluff. Had a mid elevation pocket pop. New snow seemed to have bonded well, the spot that did pop had formed into 12” slab below rock face.”

  • We toured up to Flanders Mtn and saw a big, deep 2-6' deep avalanche that broke 300-500' wide in weak snow at the bottom of the snowpack. It broke across two separate start zones and included a lower angle ridge (still around 30 degrees) in between that slid. E-NE aspect at 9,800'. HS-N-R3-D3-O.  Photo: GNFAC

  • Two skiers were ascending a northeast-facing avalanche path on the northernmost ridgeline of Mount Blackmore around 1 PM when they triggered a large, dry slab avalanche that failed 3 feet deep, 150 feet wide, and ran 500 feet vertical. Debris piled up 4-8 feet deep and broke a number of mature trees. Photo: GNFAC

  • My partner and I were approaching Responsible FamilyMan via Avalanche Gulch early yesterday morning (3/18), and once we broke through the trees into the runout zone, we stumbled across a pretty large wet avalanche debris field.

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.
