South Face of Lone Peak avalanche South Face of Lone Peak avalanche -Dec 8, 2016

The Big Sky Ski Patrol triggered this avalanche on the south face of Lone Peak with minimal explosives. It broke 3-4' deep on facets at the ground and propagated 1200' wide. This instability also exists in the backcountry. Photo: Big Sky Ski Patrol

Middle Basin snowpack Middle Basin snowpack -Dec 6, 2016

At 9,000 feet in Middle Basin/Beehive there's 2 feet of snow. Facets near the ground are breaking in some stability tests. This week's cold weather will likely allow the facets to grow bigger. Photo: A. Whitmore

Natural Avalanche at Bridger Natural Avalanche at Bridger -Dec 4, 2016

This natural avalanche occured after last Thursday's storm and appears to have failed on a layer of weak facets near the ground. It is on the south boundary of Bridger ski area, on the shoulder of Mundy's Bowl. The ski area is closed, there is no avalanche control, and a backcountry snowpack exists across the mountain.

Triggered an avalanche up Hyalite Triggered an avalanche up Hyalite -Dec 3, 2016

On my way up the Mummy 3 gully I triggered this slide on a wind-loaded pocket: 2 feet deep, 50 feet wide, 50 feet long. For climbers, small avalanches can be deadly because they push us off cliffs. Photo: Chabot/GNFAC

Wind slabs cracking Wind slabs cracking -Dec 3, 2016

Up Hyalite, on my way to climb Mummy 3, I got a wind drift to crack. Cracking is a classic sign of instability. We went higher, foolishly thinking we were through the worst of it when we triggeed a small avalanche. Photo: Chabot/GNFAC

Small avalanche Bridger Bowl - 2 December 16 Small avalanche Bridger Bowl - 2 December 16 -Dec 3, 2016

Numerous avalanches were observed in and around Bridger Bowl on Friday. Most slides were confined to the storm snow, but a few stepped down to older layers. These small slides are good reminders that larger avalanches are possible in larger terrain. Photo BBSP 

Small avalanche in Bridger Bowl Small avalanche in Bridger Bowl -Dec 2, 2016

Bridger Bowl has a backcountry snowpack. The ski area is closed, there is no avalanche control and normal backcountry precaution is necessary. Small avalanches are signs that bigger avalanches are likely. Nearby, the Apron avalanched naturally in pre-dawn hours. Photo: Bridger Bowl Ski Patrol
