Skiers outside of Cooke City triggered this small wet loose avalanche. As the surface snow heats up it looses strength and becomes more susceptible to sliding. Photo KT Miller

An over abundance of wind has created large cornices along the ridgelines. These monsters are growing weak with warming temperatures. Give cornices extra distance alonge the ridgelines and avoid traveling directly beneath them. Photo GNFAC

Snowpack and Avalanche Discussion
Bridger Range Madison Range Gallatin Range
Lionhead area near West Yellowstone Cooke City
Wet avalanches will occur today.
The ice crust is capped with this week's new snow and is a great sliding surface for wet avalanches. This picture was taken in Texas Meadow near Bridger Bowl. The crust here is 1" thick while in Taylor Fork it is 3" thick. In both areas it is supportable. Photo: GNFAC

Doug Chabot stands next to a giant pinwheel he triggered while skiing Texas Meadow north of Bridger Bowl. 5 inches of new snow sitting on a firm ice crust in combination with above freezing temperatures produced perfect conditions for wet snow instabilities. Photo GNFAC

This avalanche was observed on Friday (3/17). It likely broke from a cornice fall, and it triggered a large slab across the steep rocky terrain. Photo: P. Cronin
