From obs: "No details, came upon them while riding and making observations of the terrain. One was North-Northeast, the other was North-Northwest facing. Across the drainage from each other. Also, notice three other small avalanches on a west facing slope, about two miles east of the first two. All five were on slopes well over 30. In the centennial mountains, close to the continental on the Idaho/Montana border."

A rider triggered this avalanche while side-hilling across the bottom of the slope. The rider was able to quickly turn downhill and avoid the slide. No one was caught. Photo: Anonymous

On Sawtelle Peak, Island Park, when the clouds lifted we could see a crown of a snowmobiler triggered slide that occurred yesterday. It broke on the buried surface hoar and facets about 1.5 feet under the surface. Recent snow and wind-loading has created dangerous avalanche conditions. Photo: GNFAC

Snowpit at the Head of Hellroaring Creek on 1/7/24. Note the two stripes of surface hoar in the pit wall.

We measured 16" of low-density snow equaling 0.7" of snow water equivalent at higher elevations in the Centennial Mountains of Island Park, ID. The new snow is sitting on a couple of layers of feathery surface hoar and a weak snowpack. It will not take much wind, settlement, or new snow to push the snowpack to the breaking point.

New snow in Island Park made for beautiful views and heightened avalanche danger as the new snow fell on a snowpack riddled with weak layers. Photo: GNFAC

We snowmobiled up to 9,000' on Sawtelle peak, then skied to dig a couple pits. Our first pit was on an East aspect on a heavily wind loaded slope. The HS was 130cm (or 4.2 feet). There was 8" of new snow equal to 0.85" SWE, sitting over old consolidated snow that made up a slab over soft, weak facets about 50cm off the ground. We had ECTP24 x2 break on the old weak snow....

Went to do maintenance on the Sawtelle Snowfall weather station at 8800 ft just off the Sawtelle Mountain Road. Continuous snowcover starts around 8000 ft. At 8800 ft there is ~20" of snow with a mix of hard crusts and weak facets. These weak layers near the ground will be something to watch once snows again. Photo: GNFAC
