Authorities are warning of high avalanche dangers in northwestern Montana’s Swan mountains.
The Flathead Avalanche Center said Monday that recent heavy snowfalls in the mountains east of Bigfork increased the possibility of human-triggered and natural avalanches.
The center says the risk is most acute above 6,000 feet in elevation.
Avalanche advisories also have been issued around Whitefish, the Flathead Range, southern Glacier National Park and areas north and west of Yellowstone National Park.
That includes the Bridger, Madison and Gallatin mountain ranges and the mountains around Cooke City.
