Seven snowmobilers were playing on a slope when one person triggered this slide, but was not caught. This avalanche happened on Saturday, Jan 7 in Cabin Creek. Although it was not very deep, the debris ran into a terrain trap. Photo: J. Noorlander

Snowpack and Avalanche Discussion
The Bridger, Madison and southern Gallatin Ranges, the Lionhead area near West Yellowstone and the mountains around Cooke City:
As the weather changes so does the layering and structure of the snowpack. Without any snow events over the past week, the snowpack is slowly adjusting to last week's storm, helping improve stability. However the pack still resembles a house of cards; one wrong move and it could all come crashing down. A near miss in Cabin Creek outside of West Yellowstone on Saturday was a poignant reminder of just how unstable conditions are.
