Loose snow avalanches, N. Bridgers Loose snow avalanches, N. Bridgers -Mar 26, 2017

Natural loose snow avalanches in the northern Bridger Range after 4-6" of new snow fell. These slides began near rocky outcrops and grew large as they entrained dense new snow. Photo: G. Antonioli

Deep wet loose slide in Beehive Deep wet loose slide in Beehive -Mar 26, 2017

This slide started as a point release and gouged out weak, wet snow to the ground. It likely occurred on Thursday (3/23). Photo: A. Pohl

Wet Slide, Beehive Basin Wet Slide, Beehive Basin -Mar 25, 2017

This large wet slide in Beehive Basin was the result of above freezing temperatures, strong solar input and isothermal snow. The slide started as a point release high in the rocks and soon gouged to the ground. A full isothermal snowpack now exists up to 9,000 ft. which will make this type of avalanche more common once it warms up. Photo GNFAC  

Dry slab avalanches, Cooke City 3/23/17 Dry slab avalanches, Cooke City 3/23/17 -Mar 24, 2017

Skiers outside of Cooke City observed these dry slab avalanches in the north bowl of Abiathar. A layer of graupel is the expected weak layer. This avalanche problem won't be widespread, but it's something to consider when skiing or riding around Cooke City. Photo B. Fredlund 

Wet loose avalanche, Cooke City Wet loose avalanche, Cooke City -Mar 23, 2017

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 

Cornice Fall, Northern Madison Range Cornice Fall, Northern Madison Range -Mar 22, 2017

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 

Ice Crust under the new snow Ice Crust under the new snow -Mar 22, 2017

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

Pinwheels and Point Releases  - Texas Meadow Pinwheels and Point Releases - Texas Meadow -Mar 21, 2017

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
