Observed this avalanche on the east face of Cameahwait in the southern Flathead Range from Hwy 2 on Jan 15th at 1100. But suspect it ran sometime on the 12th/13th. Looks like a possible cornice trigger and likely that it stepped down to some persistent weak layer. Debris ran at least to 6500 ft (estimated) until it disappears out bottom of photo.
