The Gallatin National Forest Avalanche Center has issued a backcountry avalanche warning for the southern Gallatin Range, southern Madison Range and Lionhead area near West Yellowstone.Officials say heavy snowfall and strong winds are creating unstable conditions. The avalanche danger is rated high on all slopes and backcountry travel in avalanche terrain is not recommended.
Most areas picked up 4 to 6 inches of snow from Sunday morning to Monday morning, while the Cooke City area saw 8 inches of snow fall. Snow was expected to continue accumulating on Monday.
The center says recent heavy snow is resting on two distinct weak layers of snow, leading to natural avalanches that are large and destructive. Source
