This recent avalanche failed on a heavily wind-loaded slope in Sage Basin along the ridgeline. It may have initiated as a cornice fall or a wind-slab, but it broke down to deeply buried facets. Even though it was a small slope, the slide had enough power to knock down a tree and piled debris deeply at the bottom of the slope. Photo: GNFAC

Bridger Range, 2021-02-28

There was 6' of snow off the ridge in the Bridger Range on an east facing slope. The top 2 feet were recent wind drifting that broke clean in our stability test which indicated unstable conditions (ECTP18). We expect similar conditions and instability with wind-loaded slops throughout our forecast area. Photo: GNFAC

Bridger Range, 2021-02-28

In the last 24 hours (2/28) 12" of low density powder and 40-50 mph west wind made it easy to trigger wind-drifted snow. Alex kicked these drifts which cracked and moved. We expect similar conditions and instability with wind-loaded slops throughout our forecast area. Photo: GNFAC

Northern Gallatin, 2021-02-28

On Mt Ellis (2/27/21) the snowpack has 20-40cm of depth hoar and facets at the bottom. Stability tests took a lot of force to collapse this layer, but it propagated (broke across the whole column) every time once initiated. This is a poor snowpack structure that makes large avalanche possible to trigger if you hit the wrong spot on a slope. Photo: GNFAC
